[0002] FPC stands for "Flexible Printed Circuit Board." It's a printed circuit board with circuit patterns fabricated onto a flexible substrate, typically made from flexible materials such as polyimide and polyester. FPCs are widely used in consumer electronics, medical devices, automotive electronics, and industrial applications. FPC plasma cleaning equipment is a device specifically designed to clean the surface of FPCs, removing dust and impurities to facilitate subsequent wafer bonding.

[0003] After searching, Chinese patent announcement number: CN218168059U discloses a loading and unloading device for FPC plasma cleaning. By providing ventilation holes on the carrier clamp body, workers can directly place the carrier clamp body into the plasma cleaning machine for cleaning. Compared with the original method of manually removing each carrier board and placing it into the plasma cleaning machine for cleaning, this utility model greatly increases efficiency, while reducing the possibility of contamination caused by human touch and the risk of scratching the FPC of the camera module.

[0004] Although the above device aligns the notches at both ends of the carrier clamp body and the carrier clamp body to form a docking connection, thereby reducing the possibility of contamination caused by human touch and the risk of scratching the FPC of the camera module when the carrier is transferred, there is no connection mechanism between the two carrier clamps during the clamping process of transferring the carrier from one carrier clamp to another by using a push rod. It is easy to cause the two carrier clamps to shift when pushing the carrier, resulting in the inability to transfer the carrier smoothly. Therefore, an FPC board plasma cleaning device is proposed to solve the above problems. Utility Model Content

The inside of the cleaning jig 1 and the carrier clamp 2 are both provided with placement components, and the number is multiple. The placement components in the cleaning jig 1 and the carrier clamp 2 are of the same height, which is used to cooperate with the placement and transfer of the placement plate 6. The placement component includes a placement frame 5 and the number is two. The two placement frames 5 are symmetrically arranged, and a placement plate 6 is movably connected between the two placement frames 5 to cooperate with the placement of the FPC board.

[0034] like Figure 3 - Figure 4As shown, the connecting assembly 4 includes a rotating seat 41 for cooperating with the connection of various components. The rotating seat 41 is rotatably connected to the carrier clamp 2. The rear part of the rotating seat 41 is provided with a connecting rod 42 for cooperating with the connection with the limit block 3. The rear part of the connecting rod 42 passes through the limit block 3 and is movably connected thereto. The rear part of the connecting rod 42 is provided with a limiting member 43 for cooperating with the limitation of the connecting assembly 4 for front and rear limitation. The limiting member 43 is movably connected to the limit block 3 for limitation in the up, down, left and right directions. The rotating seat 41 includes a circular plate 411 for cooperating with the connection of various components. The side of the circular plate 411 close to the carrier clamp 2 is fixedly connected to a rotating block 412 for cooperating with the connection between the rotating seat 41 and the carrier clamp 2. The side of the circular plate 411 away from the carrier clamp 2 is fixedly connected to a connecting block 413 for cooperating with the connection of the connecting rod 42.

When the cleaning jig 1 is docked with the carrier clamp 2, insert the rear end of the connecting rod 42 into the limit opening 31, and then rotate the connecting rod 42 so that it drives the limit sleeve 432 to be sleeved on the outside of the limit block 3 through the vertical plate 431 fixed thereto, thereby fixing the connecting component 4 and the limit block 3, and fixing the cleaning jig 1 and the carrier clamp 2. Then, use a push rod or other pushing tool to push the placement plate 6 in the carrier clamp 2 toward the cleaning jig 1, so that both sides of the placement plate 6 are removed from the placement frame 5 in the carrier clamp 2. Slide it into the placement frame 5 of the cleaning jig 1. When the placement plate 6 is transferred, immediately rotate the connecting rod 42 again so that it drives the limit sleeve 432 to rotate to the left or right through the vertical plate 431, thereby disengaging the limit sleeve 432 from the limit block 3, and then pull the carrier clamp 2 to disengage the connecting rod 42 from the limit opening 31. Then, the cleaning jig 1 can be placed in the plasma cleaning equipment, and the FPC board on the placement plate 6 is cleaned by plasma gas. When the cleaning is completed, the cleaning jig 1 and the carrier clamp 2 are connected together through the above operation, and then the cleaned placement plate 6 is pushed from the cleaning jig 1 to the carrier clamp 2 by the pushing tool, and then the connecting rod 42 is rotated to disengage the connecting component 4 from the limit block 3.
