Problems solved by technology
[0003] However, in the above-mentioned transmission device that drives the conveyor belt through the stepping motor, when transmitting the circuit board, there are many parts that need to participate in friction to transmit the circuit board, which has high energy consumption, and the friction is easy to generate heat, and the temperature of the stepping motor is high when it is working. , the whole mechanism runs slowly, the response speed is not ideal, the stability is not high, and the positioning accuracy is low
As customers have higher and higher requirements for detection accuracy of detection equipment, the existing detection transmission device has been difficult to meet the needs of customers

The invention discloses a transmission device for double-surface detection of a circuit board. The transmission device comprises a fixing plate, wherein a stator is arranged on one side of the fixing plate; a rotor which moves relative to the stator is arranged on one side of the stator; a moving plate is arranged on the rotor; the moving plate is connected with a driving mechanism used for jacking the circuit board; swinging pneumatic grippers used for clamping and overturning the circuit board are arranged on the driving mechanism; during detection operation, the circuit board is clamped by the pneumatic grippers, the rotor controls the moving plate to drive the driving mechanism to move, and the circuit board is transmitted; and when the circuit board needs to be overturned, the driving mechanism jacks the circuit board to a certain height, the swinging pneumatic grippers overturn the circuit board by 180 degrees, and the double-surface detection of the circuit board is achieved. According to the transmission device, the driving mechanism is arranged on the rotor, the swinging pneumatic grippers can perform stable and accurate linear and reciprocating motion, the entire motion process is friction-free, the locating accuracy is high, and the transmission device has the characteristics of high accelerated speed and low power consumption, and can well adapt to detection operation of the circuit board.
Description
technical field [0001] The invention relates to the technical field of circuit board detection, in particular to a transmission device for double-sided detection of circuit boards. Background technique [0002] Such as figure 1 As shown, the existing circuit board detection transmission device is mainly composed of stepper motor 34, conveyor belt 48, belt pulley 4, sensor 57, tension pulley 64, vertical motion plate 45 and some parts. The rotary motion is converted into linear motion by the conveyor belt 48 and the pulley 4; the tested circuit board 10 is placed on the conveyor belt 48, and through the friction between the circuit board 10 on the conveyor belt 48 and the conveyor belt 48, the conveyor belt 48 drives the circuit board 10 to move together. linear motion. The angular displacement is controlled by controlling the number of pulses of the stepping motor 48, so as to achieve the purpose of accurate positioning. [0003] However, in the above-mentioned transmissi...
