Description

Technical Field

[0001] This utility model relates to the field of FPC boards, and in particular to a centrifugal washing device for FPC boards. Background Technology

[0002] FPC board, short for Flexible Printed Circuit Board, is a type of circuit board made using flexible materials. Compared with traditional rigid circuit boards, FPC boards have higher flexibility and are suitable for applications with limited space or requiring dynamic bending. FPC board centrifugal washing equipment is a device used to clean flexible printed circuit boards. Because FPC boards are usually quite delicate and fragile, special care is needed during the cleaning process to avoid damaging the circuit or affecting its performance. During the centrifugal washing process, a water washing fixing device is needed to fix and protect the FPC board to ensure its stability during cleaning.

[0003] A search revealed Chinese Patent Publication No. CN216540084U, which discloses a centrifugal washing and fixing device for a camera module. The device includes a left cleaning clamp and a right cleaning clamp, which are symmetrical. The left cleaning clamp comprises a left cleaning clamp strip and a left limiting block. The left cleaning clamp strip has vertical adjustment holes and a circular hole. The left limiting block has a circular hole at a position corresponding to the vertical adjustment hole on the left cleaning clamp strip, and the left limiting block also has vertical adjustment holes at positions corresponding to the circular holes on the left cleaning clamp strip. The left limiting block and the left cleaning clamp strip are fixedly connected together using screws and nuts through the vertical adjustment holes and the circular holes. This invention is suitable for cleaning and fixing camera modules of different heights.

[0004] The aforementioned device, while capable of vertical adjustment through the interaction between the cleaning clamp and the limiting block, is suitable for cleaning and fixing different types of camera modules. However, it requires the cooperation of multiple bolts with the vertical adjustment holes on the cleaning clamp. Since a centrifugal washing machine typically has multiple cleaning clamps fixed to its centrifugal disc, each clamp requires adjustment of multiple bolts, which are located on the side. This makes adjustment time-consuming, labor-intensive, inconvenient, and impractical. Therefore, a centrifugal washing device for FPC boards is proposed to solve these problems.

The limiting rods 12 pass through the clamping plate 22 and are slidably connected to it.

[0035] like Figure 4 - Figure 6As shown, the top of the carrier plate 3 has a limiting groove 31, the shape of which can be changed according to the actual shape of the FPC board during production. The front, rear, left and right sides of the bottom of the carrier plate 3 are fixedly connected with fixing sleeves 32, which are used to cooperate in the connection between the carrier plate 3 and the base plate 4. The upper part of the fixing sleeve 32 has an auxiliary groove 321, which is used to cooperate in the connection of the connecting component 5. The lower part of the auxiliary groove 321 is provided with an inclined annular surface 322, which is used to cooperate in the limiting of the ball 55 to cooperate in the fixation between the carrier plate 3 and the base plate 4.

[0036] Furthermore, the connecting assembly 5 includes a push plate 51 for pushing the control rod 52. The front and rear parts of the push plate 51 are provided with limiting members for cooperating with the fixed sleeve 32 to connect the carrier plate 3 and the base plate 4. The limiting members include the control rod 52 for controlling and limiting the movement of the ball 55. The control rod 52 is fixedly connected to the push plate 51. An auxiliary sleeve 53 is slidably connected to the outside of the control rod 52 for cooperating and connecting various components. The auxiliary sleeve 53 passes through the fixed sleeve 32 and is movably connected to it. A spring 54 is provided between the control rod 52 and the auxiliary sleeve 53 for cooperating with the movement and reset of the control rod 52. The upper left and right sides of the auxiliary sleeve 53 are movably connected with the ball 55 for cooperating with the fixation between the connecting assembly 5 and the fixed sleeve 32.

[0037] Furthermore, the control lever 52 includes a main lever 521, which is used to connect various components. A push ring 522 is fixedly connected to the middle of the outer wall of the main lever 521, which is used to cooperate with the push spring 54. A frustum block 523 is fixedly connected to the top of the main lever 521, and its inclined surface is used to cooperate with the retraction of the ball 55. A cylinder 524 is fixedly connected to the top of the frustum block 523, which is also used to cooperate with the retraction of the ball 55. A push block 525 is fixedly connected to the upper part of the cylinder 524, which is used to push out the ball 55 and fix the ball 55. An installation cavity 531 is opened in the middle of the inner wall of the auxiliary sleeve 53, which is used to cooperate with the installation of the spring 54. The push ring 522 is slidably connected to it. The upper and lower ends of the spring 54 are fixedly connected to the installation cavity 531 and the push ring 522, respectively. Connection ports 532 are opened on the upper left and right sides of the auxiliary sleeve 53. The ball 55 cannot be disengaged from the connection port 532. The ball 55 is movably connected to the connection port 532.

[0038] Specifically, the bottom surface of the base plate 4 is provided with a groove 41 on both the left and right sides, which is used to cooperate with the use of the button plate 51. The button plate 51 is slidably connected to it. The top front and rear front parts of the groove 41 are provided with a fixing opening 42, which is used to cooperate with the connection of the limiting member. The auxiliary sleeve 53 is fixedly connected to it. The upper part of the fixing opening 42 is provided with a connecting groove 43, which is used to cooperate with the connection of the fixing sleeve 32. The fixing sleeve 32 is movably connected to it.

[0039] Working principle: In use, first, fix the FPC board to be cleaned in the limiting groove 31 on the carrier plate 3. Then, align the fixing sleeve 32 at the bottom of the carrier plate 3 with the connecting groove 43 on the base plate 4. At the same time, press the carrier plate 3 towards the base plate 4 and press the press plate 51 towards the carrier plate 3. At this time, the press plate will push the two control rods 52 to move towards the carrier plate 3. The push ring 522 on the main rod 521 will then compress the spring 54 and push the frustum block 523 and the connected cylinder 524 and push block 525 upward, thereby causing the ball 55 in the connection port 532 to move towards the inside of the auxiliary sleeve 53, causing the ball 55 to retract into the auxiliary sleeve 53. At this time, the carrier plate 3 will be pressed against the base plate 4, and the fixing sleeve 32 will be fully pressed into the connecting groove 43. Then, release the press plate 51. At this time, the spring 54 will lose pressure and push the push ring 522 to reset. The push ring 522 will then drive the main rod 521, the frustum block 523, the cylinder 524, and so on. Push block 525 resets. As push block 525 moves downward, it pushes two balls 55 outward from the connection port 532, causing a portion of the balls 55 to protrude from the connection port 532. Simultaneously, push block 525 fixes the position of the two balls 55. At this time, the balls 55 are held in place by the inclined annular surface 322 in the auxiliary groove 321, thus fixing the connecting assembly 5 to the fixing sleeve 32. The carrier plate 3 is then fixed to the base plate 4. The fixed limiting mechanism is then inserted into the placement groove 11 on the two brackets 1. According to the thickness of the limiting mechanism, screw 21 is rotated to drive clamping plate 22 to fix the limiting mechanism. Then, the centrifuge can be turned on to centrifuge and wash the FPC board. After washing, simply rotate screw 21 in the opposite direction to loosen clamping plate 22 and then press the button 51 again to control the balls 55 to retract back into the auxiliary sleeve 53, thus separating the carrier plate 3 from the base plate 4.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
