In other embodiments, the upper surface of the lower module 1 is further provided with at least one proximity switch 16 for detecting the position of the circulation tool. Thereby judging whether the current circulation tool position is aligned or not and confirming whether circulation tools exist on the lower module 1 or not. In this embodiment, the positioning pin 15 and the proximity switch 16 are provided at the same time.

Considering the structure of the shell part, the adhesive-back coating is generally performed on the flexible material to perform the lamination, in order to ensure a good bonding effect, the adhesive-back is generally activated by hot pressing, specifically, referring to fig. 4, the press working apparatus 100 further includes a plurality of heating structures 4, the plurality of heating structures 4 are correspondingly disposed on the periphery of the press working structure 21, each heating structure 4 includes a heating rod and a temperature control device that are electrically connected, so as to locally heat the press working structure 21, control the heating rod to continue heating when the temperature does not meet the working condition, and control the heating rod to stop heating when the temperature meets the requirement, specifically, two heating rods are disposed on each sliding portion 212, and each heating rod corresponds to a temperature sensing line to serve as the temperature control device.
