[0026] In this embodiment, a working chassis is also included, in which a workbench is installed, and the pressing device 1, the plastic cap feeding device 2 and the screw feeding device 3 are all installed on the workbench; the working chassis uses an aluminum profile structure, which greatly reduces the cost of the device and is sufficient to meet the use requirements of the device. The device is provided with two feeding mechanisms, one for feeding the plastic caps and the other for feeding the screws. The pressing device 1 is integrated to realize fully automatic pressing of plastic caps, which basically does not require human intervention, thereby improving overall work efficiency.

[0027] In this embodiment, the X-axis translation mechanism 12 of the pressing device 1 is driven by a closed-loop stepping and synchronous belt. The synchronous belt uses the S3M specification, the synchronous wheel uses 25 teeth, the lead is equivalent to 75MM, and the maximum speed of the equipment can reach 1000mm / s; and the Z-axis lifting mechanism 13 is driven by a servo motor and a screw rod to drive the pressing mechanism to lift and lower, and then press the plastic cap. The pressing mechanism uses vacuum adsorption to complete the material removal. A first pressure rod 17 is provided in the middle of the vacuum suction nozzle 18 to press the plastic cap onto the screw rod.

[0028] During operation, the plastic cap and the screw are manually placed in the plastic cap feeding device 2 and the screw feeding device 3 respectively. The plastic cap feeding device 2 and the screw feeding device 3 feed the plastic cap and the screw to the feeding position and the pressing position respectively. Then, the pressing mechanism moves to the feeding position, sucks the plastic cap through the vacuum suction nozzle 18, and then moves to the pressing position to press the plastic cap onto the screw.

[0029] In one embodiment, a first slide rail is also installed on one side of the first lifting seat 14 in the vertical direction, and a first slider is also slidably connected to the first slide rail; the first fixed block 16 is fixedly connected to the lower part of one side of the first lifting seat 14, and a first through hole is also opened on the first fixed block 16; the first lifting block 15 is L-shaped, and the L-shaped vertical end of the first lifting block 15 is arranged through the first through hole and connected to the first slider; the L-shaped horizontal end of the first lifting block 15 is arranged below the first fixed block 16, and the vacuum nozzle 18 is installed at the bottom of the L-shaped horizontal end of the first lifting block 15.
