[0027] like Figure 1 and Figure 2As shown, the utility model proposes a colloid pressing device 10 for pressing colloids on a circuit board. The colloid pressing device 10 may include at least one colloid pressing unit. Moreover, the colloid pressing unit may include a mounting seat 100, a lifting drive mechanism 200 disposed on the mounting seat 100, a pressing block mechanism 300 slidably disposed on the mounting seat 100 and connected to the lifting drive mechanism 200, and a pressure detection structure 400 disposed on the pressing block mechanism 300, and the pressure detection structure 400 is connected to the lifting drive mechanism 200. The lifting drive mechanism 200 can drive the pressing block mechanism 300 to move up and down, so that the pressing block mechanism 300 can press the colloid to be pressed, and during the pressing, the pressure detection structure 400 can also detect the pressure applied to the colloid by the pressing block mechanism 300, so as to adjust the pressure applied to the pressing block mechanism 300 by the lifting drive mechanism 200.

[0029] When a pressing machine is needed to press the colloid (such as pressure-sensitive adhesive or heat-sensitive adhesive) of electronic components or circuit boards, the lifting drive mechanism 200 on the mounting seat 100 can drive the connecting block 310 of the pressing block mechanism 300 that is slidably connected to the mounting seat 100 to move up and down, which can drive the pressing block structure 320 that is slidably connected to the connecting block 310 to move up and down, so that the pressing block structure 320 gradually approaches the colloid to apply pressure to it; and in the process of applying pressure, the pressure applied to the pressing block structure 320 can be detected by the pressure detection structure 400 arranged between the connecting block 310 and the pressing block structure 320, so that the pressure applied to the colloid by the pressing block structure 320 can be detected.

[0035] Further, one of the pressing main block 322 and the connecting block 310 has a connecting groove 312, and the other has a connecting protrusion 3222, the connecting protrusion 3222 is slidably connected to the side wall of the connecting groove 312, and the pressure detection structure 400 is arranged between the groove bottom surface of the connecting groove 312 and the top surface of the connecting protrusion 3222.
