The fixing frame is assembled from multiple components, making it easier to manufacture, repair, and replace, as well as to connect different plug-in rods 161. Specifically, worn components such as the driven pulley 162 or plug-in rod 161 can be replaced by simply removing the mounting block, or a plug-in rod 161 of a different specification can be replaced by removing and replacing the mounting block.

[0037] In this embodiment, the mounting block 114 is located on one side of the first plate body 111, and the plug-in rod 161 is rotatably connected to the mounting block 114 through the driven pulley 162.

[0044] Please refer to Figure 2 In this embodiment, the connecting rod assembly 14 includes a driving rod 141 , a first connecting rod 142 , and a supporting member 143 .

[0045] One end of the driving rod 141 is fixedly connected to the output end of the first driving member 12, and the other end of the driving rod 141 is rotatably connected to the first connecting rod 142. The end of the first connecting rod 142 away from the driving rod 141 is rotatably connected to the plug-in rod 161. The support member 143 is located between the driving rod 141 and the plug-in rod 161, and one end of the support member 143 is rotatably connected to the first connecting rod 142. The first driving member 12 drives the driving rod 141 to rotate, and the driving rod 141 can drive the first connecting rod 142 to rise and fall and rotate, thereby driving the plug-in rod 161 to rise and fall. The cooperation of the support rod 143, the first connecting rod 142, and the connecting block 164 can enable the plug-in rod 161 to be raised and lowered quickly, efficiently, and stably.

[0046] Among them, the first connecting rod 142 in this embodiment is connected to the plug-in rod 161 through the second connecting rod 144, one end of the second connecting rod 144 is rotatably connected to the first connecting rod 142, and the other end of the second connecting rod 144 is provided with a connecting groove, and a locking block 145 is provided in the connecting groove, and a locking hole is provided on the locking block 145.

The bottom frame member 115 is fixedly connected to the bottom surface of the first plate body 111, and the mounting block 114 is fixedly connected to the side of the bottom frame member 115. The bottom frame member 115 facilitates the compact direct-connected high-speed vertical plug-in head device to be firmly set on the plug-in machine, and at the same time, different bottom frame members 115 can be set to adapt to installation applications on different plug-in machines.

[0049] Please refer to Figure 1 In this embodiment, a first sensor 172 and a second sensor 174 are mounted on the cam rod 151. A first sensor 171 for sensing the first sensor 172 and a second sensor 173 for sensing the second sensor 174 are mounted on the fixed frame. The first sensor 171 provides feedback indicating that the first driving member 12 has reached its designated position, while the second sensor 173 provides feedback indicating that the second driving member 13 has reached its designated position.

[0050] The first sensing member 172 and the second sensing member 174 can be rotated on the cam rod 151 to a desired position, and then fixed on the cam rod 151 by tightening screws, for example.

[0051] The working principle of this utility model is as follows: When a circuit board moves below the insertion rod 161 and requires insertion, the first drive member 12 first activates and drives the insertion rod 161 downward via the connecting rod assembly 14. During this process, the cam assembly 15 rotates accordingly as the insertion rod 161 descends. When the sensor 171 detects that the insertion rod 161 has descended to a preset position, the first drive member 12 stops, and the second drive member 13 activates and drives the insertion rod 161 further downward via the cam assembly 15, completing the insertion of the circuit board. During this process, the connecting rod assembly 14 also rotates accordingly as the insertion rod 161 descends.

[0052] After the plug-in is completed, the second driving member 13 and the first driving member 12 work in sequence to drive the plug-in rod 161 to rise and reset.

[0053] This completes the plug-in process of the compact, direct-connected, high-speed vertical plug-in head device of the preferred embodiment.

[0054] A compact direct-connected high-speed vertical plug-in head device in this preferred embodiment drives the plug-in rod to move up and down towards or away from the circuit board by setting a first driving member in combination with a connecting rod assembly, and at the same time drives the plug-in rod to move up and down into the plug-in by combining a second driving member with a cam assembly, which can perform high-precision and stable plug-in, with high-speed and high efficiency and good plug-in effect.
