[0035] a profiled carrier 4, the profiled carrier 4 includes a base 41 and a guide plate 42, the base 41 is connected to the moving platform 3, two slots are symmetrically opened at the top of the base 41; the guide plate 42 is of a concave-shaped structure, including a main body part and plug-in parts vertically connected to both ends of the main body part, the guide plate 42 is plugged into the slots through the plug-in parts, and a receiving groove is formed between the main body part and the base 41, and a profiled through hole 421 communicating with the receiving groove is opened on the main body part.

[0036] Working process: In the initial state, the moving platform 3 is located on one side away from the pressing component 2. First, place the product with the PCB board to be installed on the fixed position on the base 41 (the fixed position is between the two slots), and then insert the guiding plate 42 into the slots of the base 41. At this time, the product is located in the accommodating groove formed between the guiding plate 42 and the base 41 and corresponds to the position of the profiling through hole 421. Then, place the PCB board into the profiling through hole 421 (the shape of the profiling through hole 421 corresponds to the shape of the PCB board). Next, control the second driving source 31 to drive the moving platform 3 to move below the pressing platform 22 (at this time, the position of the first pressing head 23 corresponds to the position of the PCB board). The first driving source 24 drives the pressing platform 22 to move downward. The first pressing head 23 at the bottom of the pressing platform 22 gradually approaches the PCB board and finally presses the PCB board onto the product. After the pressing is in place, the first driving source 24 performs pressure holding according to the time set by the time-delay relay 25.
