Description

Technical Field

[0001] The utility model belongs to the technical field of automatic insertion in display panels, and particularly relates to an elastic clamping device and a PCB board clamping device. Background Art

[0002] During the production process of a display panel, it is necessary to perform lighting detection on it. Usually, the display panel PCB board (printed circuit board) is electrically connected to a signal generator to achieve the purpose of lighting. The PCB board has FPC (flexible printed circuit) and FFC (flexible flat cable) docking interfaces. During detection, the FPC and FFC need to be automatically inserted into the connectors of the PCB board. Since the opening sizes of the PCB board connectors and the docking of the FPC and FFC are small, if the incoming PCB board is loose and not firmly clamped, it is easy to cause the insertion failure of the FPC and FFC, affecting the product yield.

[0003] Currently, in automatic insertion equipment, the PCB board is mainly fixed by the adsorption of the suction cups on the carrier table. There is still the problem that the PCB board is not firmly clamped, which affects the subsequent insertion process and the insertion yield of the product. At the same time, to avoid damaging the product during the clamping process, there is an urgent need for a clamping device that can firmly clamp the PCB board to solve the above-mentioned technical defects. Summary of the Utility Model

[0004] The purpose of the utility model is to solve all or part of the above problems, and provides an elastic clamping device and a PCB board clamping device. The technical solution of the utility model is as follows: During the process of approaching and clamping the PCB board, the elastic clamping device compresses the spring for buffering to avoid damage to the equipment and the product. The PCB board is placed on the adsorption carrier table, and the PCB board is jointly clamped by the adsorption carrier table and the elastic clamping device, integrating two structures of vacuum adsorption and clamping, making the clamping of the PCB board more reliable and stable, ensuring that the PCB board will not move in the Z direction and the XY direction during the automatic board insertion process, and improving the insertion success rate.

[0005] The utility model provides an elastic clamping device, which includes a pressing module and a base. The pressing module includes a PCB board positioning pressing block and an elastic moving component. The PCB board positioning pressing block is fixedly connected to the elastic moving component. A guiding shaft is provided in the base, and the elastic moving component is sleeved outside the guiding shaft and connected to the base. By clamping the PCB board with the elastic clamping device, the stability of the PCB board during the automatic insertion process is ensured, and the insertion success rate of the product is improved.

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

[0007] The end of the PCB board positioning press block is equipped with a pitch adjustment device to adjust the inclination angle of the PCB board positioning press block, which is convenient for adjusting the angle of the PCB board positioning press block according to different specifications and sizes of the PCB board, and avoiding damage to the PCB board during the clamping process.

[0008] The front end of the PCB board positioning press block is wedge-shaped, which is convenient for fixing the PCB board.

[0009] The PCB board positioning press block is made of stainless steel material, which has the characteristics of corrosion resistance and high strength, and is easy to maintain.

[0010] The elastic moving component includes a compression spring and a moving slider. One end of the compression spring abuts against the base, and the other end abuts against the moving slider. When the PCB board positioning press block contacts the PCB board, the compression spring can be compressed for buffering, driving the movement of the moving slider.

[0011] A groove is provided at the top of the base. The elastic moving component drives the PCB board positioning press block to slide along the guide shaft within the length range of the groove. When the PCB board positioning press block approaches the PCB board, the elastic moving component drives the PCB board positioning press block to move for buffering, avoiding damage to the equipment and the PCB board caused by collision.

[0012] A PCB board clamping device includes the elastic clamping device, and also includes a base, an adsorption stage, a first track and a second track. The elastic clamping device is fixedly installed on the base, and the base is installed on the first track through a slider; the adsorption stage is installed on the second track through a slider. The PCB board is placed on the adsorption stage 2 by two methods of adsorption and clamping to ensure the stability of the PCB board during the insertion process and ensure the insertion success rate.

[0013] A cylinder is connected under the elastic clamping device. The cylinder drives the elastic clamping device to move through the first track, approach the adsorption stage to clamp the PCB board, and cooperate with the adsorption stage to clamp the PCB board.

[0014] One or more elastic clamping devices are installed on the first track. For different specifications and sizes of the PCB board, the number of elastic clamping devices can be adjusted to facilitate the process.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: a compression spring is provided in the elastic clamping device, and the compression spring can be compressed for buffering when the PCB board positioning press block contacts the PCB board, avoiding damage to the product and the equipment; the PCB board clamping device integrates two structures of the elastic clamping device and the adsorption stage, and fixes the PCB board by two methods of vacuum adsorption and elastic clamping, ensuring that the PCB board will not move in the Z direction and the XY direction during the automatic board insertion process, and the PCB board is clamped more firmly, improving the product yield.

According to the size specification of the PCB board, the pitching angle of the PCB board positioning press block 111 is adjusted to reduce equipment and product damage.

[0027] The front end of the PCB board positioning press block 111 is wedge-shaped for facilitating the fixation of the PCB board; at the same time, the PCB board positioning press block 111 is made of stainless steel material, which has the characteristics of corrosion resistance and high strength and is easy to maintain.
