Press fixture

A press fixture, comprising:

• a carrier board,
• a power unit and a pressing unit attached on the carrier board and arranged at a certain distance with each other;
• a retractable unit and a pushing block, one end of the retractable unit being fixedly connected to the power unit and another end of the retractable unit being fixedly connected to the pushing block;
• wherein the power unit drives the retractable unit to retract so that the retractable unit brings the pushing block to move between the power unit and the pressing unit, for pressing a first piece to be pressed and a second piece to be pressed located between the pushing block and the pressing unit;
• wherein the press fixture further comprising a sensing unit and a power control unit;
• wherein the sensing unit comprises a transmitter module and a receiver module, the transmitter module is embedded into the carrier board between the power unit and the pressing unit, and the receiver module is connected with the power unit and is arranged opposite to the transmitter module;
• the receiver module receives a signal from the transmitter module when the retractable unit retracts to expose the transmitter module;
• the receiver module is in communication with the power control unit, and the power control unit is in communication with the power unit;
• wherein the pressing unit comprises a pressing module and a yielding module, when the retractable unit extends to press the first and the second pieces to be pressed, the pressing module of the pressing unit and the second piece to be pressed are pressed together, and a gap is formed between the yielding module of the pressing unit and the first piece to be pressed;
• wherein the pressing module comprises a pressing area and a non-pressing area such that, while the pressing module is used for pressing the second piece to be pressed comprising a pressable portion and a non-pressable portion, when the retractable unit extends to press the first and second pieces to be pressed, the pressing area of the pressing module and the pressable portion of the second piece to be pressed are pressed against each other, and the non-pressing area of the pressing module and the non-pressable portion of the second piece to be pressed have a gap formed therebetween;
• wherein the press fixture further comprises a positioning post which, upon placement of the first piece to be pressed and the second piece to be pressed, aligns the pressing area of the pressing module with the pressable portion of the second piece to be pressed, and aligns the non-pressing area of the pressing module with the non-pressable portion of the second piece to be pressed.
