Technical Field

[0001] The invention relates to the technical field of automatic screw machines, in particular to an automatic screw machine for producing fire-fighting lighting emergency power supplies. Background Art

[0002] The fire emergency power supply can provide power for lamps when the mains power is disconnected. It is widely used in various fire emergency lighting fixtures. The fire emergency power supply is connected to the lamp, mostly by placing the power cord of the lamp on the terminal block of the circuit board in the fire emergency power supply box and fixing it with wiring screws.

[0003] In the process of installing the circuit board, many screws need to be installed on the circuit board to fix the circuit board.

[0018] 1. When the second tank chain drive assembly in the present invention is working, it drives the jig fixing table to move in the front and rear directions on the longitudinal slide rail, which is convenient for the movement of the workbench. The first tank chain drive assembly can drive the Z-axis drive box to move on the horizontal defense line, and the Z-axis slide rail, slide seat, fixed seat, chuck seat and screwdriver move synchronously with the Z-axis drive box on the transverse slide rail to adjust the horizontal position of the screwdriver.

[0019] 2. In the present invention, the positioning of the workpiece is completed by the positioning pin, and then the clamping assembly is actuated to achieve the top clamping and limiting of the workpiece, thereby completing the fixation of the workpiece and preventing the workpiece from shifting during the screw driving process and affecting the subsequent screw positioning accuracy. When the clamping assembly is working, the telescopic cylinder extends outward, which can drive the articulated seat to move upward, thereby pushing the driving rod upward under the action of the connecting plate, thereby driving the pressing plate to rotate downward through the lever action of the clamping frame relative to the rotating shaft, thereby prompting the pressing plate to press on the surface of the workpiece, thereby achieving the clamping and limiting effect on the workpiece.

[0020] 3. When the clamping assembly of the present invention performs the clamping operation, the pressure air bag is squeezed to cause the gas inside the pressure air bag to be introduced into the positioning rubber sleeve through the air guide tube, so that the positioning rubber sleeve can expand, and the filling and clamping of the positioning hole on the circuit board is completed, ensuring that the circuit board will not shake after being positioned by the positioning rubber sleeve, thereby improving the installation stability of the screw; when the clamping assembly releases the clamping operation, the gas on the workbench can be sucked into the slag collecting tray through the cleaning hole, and at the same time, the dust, particles and impurities on the circuit board and at the corresponding positions of the cleaning hole will fall into the slag collecting tray under the adsorption effect of the gas, causing the dust, particles and impurities to be collected in the slag collecting tray, and the gas will be introduced into the pressure air bag along the air pipe, causing the pressure air bag to expand and reset, thereby completing the cleaning of the circuit board and improving the cleanliness.
