Technical Field

[0001] This utility model relates to the field of keyboard manufacturing technology, specifically to a flexible FPC flip module suitable for detecting the light effect of backlit keyboards. Background Technology

[0002] A keyboard is a device for inputting instructions and data to operate computer equipment. It also refers to a set of function keys arranged by a system to operate a machine or device. A keyboard is also part of keyboard musical instruments, and can refer to musical instruments that use keyboards, such as pianos, digital pianos, or electronic keyboards. Keyboards are helpful for practicing typing. The keyboard is the most commonly used and primary input device. Through the keyboard, English letters, Chinese characters, numbers, punctuation marks, etc., can be input into the computer, thereby issuing commands and inputting data. There are also keyboards with various shortcut keys. Over time, independent products with various shortcut functions have gradually appeared on the market, sold separately with dedicated drivers and configuration software, allowing for personalized operation on compatible computers.

[0003] During keyboard assembly, the produced flexible FPC circuit board needs to be flipped for inspection to determine its light effect and whether the product is qualified. However, the existing flipping device uses a robotic arm to hold the flexible FPC circuit board, which can easily cause the flexible FPC circuit board to break or bend excessively during flipping. Therefore, there is an urgent need for a flexible FPC flipping module suitable for backlit keyboard light effect inspection to overcome the above defects. Summary of the Invention

[0004] The purpose of this invention is to provide a flexible FPC flip module suitable for backlit keyboard light effect detection, which has the advantages of easy flipping and good clamping effect, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flexible FPC flip module suitable for backlit keyboard light effect detection, comprising a base, a lifting assembly, a flip assembly, a damping limiting assembly, and an electrostatic chuck. The lifting assemblies are all located on both sides of the top of the base, the flip assembly is located inside the lifting assembly, the damping limiting assembly is located on the left side of the flip assembly, and the electrostatic chuck is located at the bottom of the damping limiting assembly, with a total of three chucks. The lifting assembly includes a fixed rod, a positioning groove, a first cylinder, a limiting seat, a positioning slide rod, and a mounting block. The flip assembly includes a mounting plate, a second cylinder, a slide groove, a rack, a gear, and a slider.

[0007] Furthermore, the bottom of the first cylinder extends through the inner cavity of the positioning groove and is fixedly connected to the top of the limiting seat. The positioning slide rod slides in the inner cavity of the limiting seat, and the bottom of the positioning slide rod is fixedly connected to the top of the base. An installation block is fixedly installed on the relatively close side of the limiting seat.

[0008] Furthermore, the connecting rods slide around the perimeter inside the positioning block, the connecting plate is fixedly installed on the top of the connecting rod, the pressure plate is fixedly installed on the bottom of the connecting rod, and the top of the electrostatic chuck is fixedly connected to the bottom of the pressure plate.

[0009] Furthermore, a spring is sleeved on the surface of the connecting rod, a groove is provided inside the mounting block on the right side, a slider is slidably connected inside the groove, and a toothed rod is fixedly installed on the left side of the slider.

[0013] This invention increases the stability of the overall device by setting a base, adjusts the position of the flipping component and the damping limiting component vertically by setting a lifting component, flips the damping limiting component by setting the flipping component, and dampens the electrostatic chuck by setting the damping limiting component, so that the electrostatic chuck can better adhere and fix with the flexible FPC circuit board. In use, the first cylinder is opened, which drives the limiting seat to move downward, so that the mounting block moves the flipping component, the damping limiting component, and the electrostatic chuck downward. After moving to the designated position, the electrostatic chuck adheres to the flexible FPC circuit board. At the same time as pressing down, the positioning block drives the spring and the damper to move downward, so that the electrostatic chuck adheres to the flexible FPC circuit board. The flexible FPC circuit board is precisely bonded. After bonding, the flexible FPC circuit is fixed by the electrostatic chuck. After fixing, the first cylinder drives the limit seat to move upward, causing the flipping component, damping limit component, electrostatic chuck and flexible FPC circuit to move upward. After moving to the designated position, the second cylinder is opened. The second cylinder drives the rack to move, and the rack causes the gear to drive the positioning block to rotate, thereby flipping the electrostatic chuck and flexible FPC circuit. It has the advantages of convenient flipping and good clamping effect. It solves the problem that the existing flipping device is used by a robot arm, which is prone to breakage or excessive bending of the flexible FPC circuit board during flipping.

[0021] More specifically, by setting the damping limiting component 4 to dampen the electrostatic chuck 5, the electrostatic chuck 5 can better adhere and fix to the flexible FPC circuit board. During use, the first cylinder 23 is opened, which drives the limiting seat 24 downwards. This causes the mounting block 26 to move the flipping component 3, the damping limiting component 4, and the electrostatic chuck 5 downwards. After moving to the designated position, the electrostatic chuck 5 adheres to the flexible FPC circuit board. Simultaneously, the positioning block 45 drives the spring 42 and the damper 46 downwards, thereby ensuring that the electrostatic chuck 5 adheres to the flexible FPC circuit board. The C-circuit board is precisely bonded. After bonding, the flexible FPC circuit is fixed by the electrostatic chuck 5.

[0023] In some embodiments, the bottom of the first cylinder 23 extends through the inner cavity of the positioning groove 22 and is fixedly connected to the top of the limiting seat 24. The positioning slide rod 25 slides in the inner cavity of the limiting seat 24, and the bottom of the positioning slide rod 25 is fixedly connected to the top of the base 1.
