DETAILED DESCRIPTION

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1-Figure 4 As shown, a truss assembly of a loading and unloading robot includes a connecting arm 211 and a truss connecting plate 212 arranged below the connecting arm 211 and connected to the connecting arm 211, a motion connecting assembly 214 is connected below the truss connecting plate 212 via at least one transverse connecting bar 213, at least one longitudinal connecting bar 215 is connected below the motion connecting assembly 214 via a truss structure connecting assembly 23, and a plurality of pressure plate robots 216 are connected to the sides of the longitudinal connecting bar 215 via the truss structure connecting assembly 23.

[0017] In this embodiment, at least one of the transverse connecting strips 213 is provided with an air storage chamber therein.

[0018] In this embodiment, the motion connection assembly 214 includes a motion connection plate 2144 and a connecting rod 2141 arranged below the motion connection plate 2144, and a compression spring 2142 is sleeved on the connecting rod 2141. The end of the connecting rod 2141 away from the motion connection plate 2144 is connected to the truss structure connection assembly 23 through a transition connection plate 2143, and the truss structure connection assembly 23 is connected to the longitudinal connecting bar 215.

[0019] In this embodiment, the truss structure connection assembly 23 includes a connection bolt 231 and a connection block 232 connected to the connection bolt 231 .

[0020] In this embodiment, the pressure plate manipulator 216 includes a pressure plate cylinder 2161 and a pressure plate piston rod 2162 that moves up and down along the pressure plate cylinder 2161 . A PCB pressure plate 2163 is provided at one end of the pressure plate piston rod 2162 away from the pressure plate cylinder 2161 .

[0021] When this component is working, it is connected to the motion drive mechanism through the connecting arm 211 and moves accordingly. The truss connecting plate 212, the transverse connecting bar 213 and the longitudinal connecting bar 215 constitute the basic structure of the manipulator truss 21. The connecting rod 2141 and the compression spring 2142 of the motion connecting component 214 are used together, and the connection bolt 231 of the truss structure connecting component 23 is set. The elastic force of the compression spring 2142 and the connection bolt 231 can realize the leveling of the entire manipulator truss, ensuring that the entire manipulator truss is in a relatively balanced state.

[0022] The setting of the air storage chamber can store a certain amount of compressed air inside it, providing compressed air for the pressure plate manipulator 216 without the need for a separate external air source, which is more convenient to use.

[0023] The pressing plate manipulator 216 is used to press the PCB sheet before processing. When working, compressed air is introduced. Under the driving action of the compressed air, the pressing plate piston rod 2162 moves up and down, driving the PCB pressing plate 2163 to move up and down. When moving downward, the PCB pressing plate 2163 presses the PCB sheet, and when moving upward, the PCB pressing plate 2163 releases the PCB sheet. In this way, the up and down movement can realize the pressing and loosening of the PCB sheet.

[0024] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
