In one embodiment, the positioning device further comprises: a heating assembly; the heating assembly includes: the device comprises a sliding seat, a heat conducting block arranged on the sliding seat and a transverse moving driver connected with the sliding seat; the transverse moving driver is used for driving the sliding seat to move so as to adjust the distance between the heat conducting block and the positioning plate. The heating assembly is arranged aiming at the condition that the workpiece needs to be heated when in pressing and positioning. When the pressing arm presses and positions the workpiece, the transverse moving driver drives the sliding seat to move towards the workpiece placed on the positioning plate, the heat conducting block is made to contact with the workpiece, and heat is generated by the heat conducting block and is transmitted to the workpiece.
In one embodiment, the heating assembly further comprises: the connecting rod is hinged on the mounting seat; one end of the connecting rod is hinged with the sliding seat, and the other end of the connecting rod is hinged with the transverse moving driver. The crank driving structure is formed among the mounting seat, the connecting rod, the sliding seat and the transverse moving driver by utilizing the mounting seat and the connecting rod, so that the relative position between the transverse moving driver and the sliding seat is adjusted, and the mounting compactness among all parts of equipment is improved.
In one embodiment, the heating assembly further comprises: a second position sensor connected to the slide; the second position sensor is used for detecting the distance between the sliding seat and the mounting seat so as to judge whether the sliding seat slides to a preset heating position. When the second position sensor detects that the sliding seat reaches the preset heating position, a brake electric signal can be sent to the transverse moving driver, and therefore automatic operation is achieved.
