Description

Technical Field

[0001] The invention belongs to the technical field of automatic plug-in, and in particular relates to a PCB board clamping device and a clamping method provided with an elastic clamping device. Background Art

[0002] During the production process of display panels, they need to be lit up for testing, which is usually achieved by electrically connecting the display panel PCB (printed circuit board) to a signal generator. The PCB has FPC (flexible printed circuit board) and FFC (flexible flat cable) docking interfaces. During testing, the FPC and FFC need to be automatically plugged into the connector of the PCB. Since the opening size of the PCB connector and the FPC and FFC docking is small, if the PCB material is loose and not firmly clamped, it is easy to cause the FPC and FFC to fail to plug in, affecting the product yield.

[0003] At present, in automatic plug-in equipment, PCB boards are mainly fixed by the adsorption effect of the suction cups on the carrier. There is still the problem of loose clamping of the PCB boards, which affects the subsequent plug-in process and the plug-in yield of the product. At the same time, it avoids damage to the product during the clamping process. There is an urgent need for a clamping device and method that can firmly clamp the PCB boards to solve the above-mentioned technical defects. Summary of the invention

[0004] The purpose of the present invention is to solve all or part of the above problems, and to provide a PCB board clamping device and a clamping method provided with an elastic clamping device. The technical solution of the present invention is as follows: a compression spring is provided in the elastic clamping device, which compresses and buffers the PCB board during the process of clamping the PCB board, thereby avoiding damage to the equipment and products; the PCB board is placed on an adsorption carrier, and the PCB board is clamped by the adsorption carrier and the elastic clamping device, integrating the two structures of vacuum adsorption and clamping, so that the PCB board is clamped more firmly and stably, ensuring that the PCB board will not move in the Z direction and XY direction during the automatic board insertion process, thereby improving the success rate of plugging.

[0005] The present invention provides an elastic clamping device, comprising a pressing module and a base, wherein the pressing module comprises a pressing component and an elastic moving component, wherein the pressing component is fixedly connected to the elastic moving component; a guide structure is provided in the base, wherein the elastic moving component is sleeved outside the guide structure and connected to the base; and the elastic clamping device is connected to a cylinder, wherein the cylinder drives the elastic clamping device to move. The elastic clamping component is driven to move by the cylinder to clamp the PCB board, thereby ensuring the stability of the PCB board during the automatic plug-in process and improving the success rate of product plug-in.

[0006] The pressing component is located outside the base, and the elastic moving component is located inside the base. The elastic moving component can drive the PCB board pressing block to move.

[0007] A pitch adjustment device is installed at the end of the pressing assembly to adjust the tilt angle of the pressing assembly, which is convenient for adjusting the tilt angle according to different specifications and sizes of PCB boards to avoid damage to the PCB boards during the clamping process; the pressing assembly is made of stainless steel material, which has the characteristics of corrosion resistance and high strength and is easy to maintain. At the same time, the front end of the pressing assembly is wedge-shaped, which is convenient for fixing the PCB board.

[0008] The elastic moving component includes a compression module and a moving slider, one end of the compression module abuts against the base, and the other end abuts against the moving slider. The compression module can compress and buffer in the process of approaching and clamping the PCB board, driving the moving slider to move.

[0009] The compression module is a compression spring, and the movable slider is driven to move by the compression and rebound of the compression spring.

[0010] A groove is provided on the top of the base, and the elastic moving component drives the pressing component to slide along the guide shaft within the length range of the groove. When the PCB board pressing block approaches the PCB board, the elastic moving component drives the PCB board pressing block to move for buffering, thereby avoiding damage to the equipment and the PCB board caused by collision.

[0011] A PCB board clamping device comprises an elastic clamping device, a base, an adsorption platform, a first track and a second track, wherein the elastic clamping device is fixedly mounted on the base, the base is mounted on the first track via a slider, and the adsorption platform is mounted on the second track via a slider. The PCB board is placed on the adsorption platform 2 and is adsorbed and clamped to ensure the stability of the PCB board during the plug-in process and the plug-in success rate.

[0012] One or more elastic clamping devices are installed on the first track. For different specifications and sizes of PCB boards, the number of the elastic clamping devices can be adjusted to facilitate the process.

[0013] A clamping method using a PCB board clamping device, using the PCB board clamping device for clamping, comprising the following steps: S1: placing the PCB board on the adsorption platform; S2: the adsorption platform adsorbs the PCB board; S3: the cylinder moves to drive the elastic clamping component to approach the PCB board, the pressing component clamps the PCB board, and when the pressing component contacts the PCB board, the compression spring can be compressed for buffering.

[0014] The pressing component can adjust the pitch angle through the pitch adjustment device according to the specifications of the PCB board. When the pitch adjustment device is pushed down, the front end of the pressing component is tilted up; when the pitch adjustment device is pulled up, the front end of the pressing component is pressed down.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: a compression spring is provided in the elastic clamping device, and when the PCB board pressing block contacts the PCB board, the compression spring can be compressed and buffered to avoid damage to the product and equipment; at the same time, the PCB board clamping device integrates two structures, the elastic clamping device and the adsorption carrier, and fixes the PCB board by vacuum adsorption and elastic clamping, ensuring that the PCB board will not move in the Z direction and the XY direction in the automatic board insertion line process, and the PCB board is clamped more firmly, thereby improving the product yield.
