DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0031] like Figure 1 As shown, an assembly robot is based on a material conveyor belt 1, which is used to arrange the conductive circuit boards. The two side plates of the material conveyor belt 1 extend upward so that the circuit boards conducted by the material conveyor belt 1 can be neatly arranged.

[0032] like Figure 2 , Figure 3 , Figure 4 As shown, the front end of the material guide conveyor belt 1 is fixed with a suspension 3, an electric push rod 31 is vertically installed on the surface of the suspension 3, a lifting plate 4 is arranged below the suspension 3, both sides of the lifting plate 4 extend vertically downward, two guide rods 32 are symmetrically fixed on the top of the lifting plate 4, the guide rods 32 slide through the suspension 3, two movable plates 5 are symmetrically flat against the vertical parts on both sides of the lifting plate 4, a slide groove 51 is provided on the surface of the movable plate 5, both sides of the lifting plate 4 are provided with sliders, the sliders slide vertically with the slide groove 51, a spring is connected between the movable plate 5 and the lifting plate 4, so that the bottom end of the lifting plate 4 is higher than the bottom end of the movable plate 5;

[0033] The bottom of the two movable plates 5 are both elastically rotated to install the carrying bars 6 through the torsion spring. The two carrying bars 6 are flipped toward the inside of the movable plate 5 by the elastic force to keep the horizontal state. The lower part of the movable plate 5 is provided with a resistance member 7, which is lower than the carrying bars 6.

[0034] A conveying device for the housing of the communication device is arranged below the two carrier strips 6, and is used for conveying the housing of the communication device one by one through the bottom of the carrier strips 6. The surface of the guide conveyor belt 1 is arranged to convey the circuit board. The circuit board moves to between the movable plates 5 and is supported by the two carrier strips 6. The electric push rod 31 is turned on and extended. Under the guidance of the guide rod 32, the lifting plate 4, the movable plate 5, the carrier strips 6 and the circuit board are lowered. The resistance member 7 first contacts the housing of the communication device, so that the movable plate 5 cannot continue to descend. The height of the circuit board remains fixed. The electric push rod 31 continuously pushes the lifting plate 4 to descend, so that the lifting plate 4 overcomes the elastic force and moves relative to the movable plate 5. The bottom end of the lifting plate 4 presses the carrier strips 6 downward, so that the carrier strips 6 are flipped outward, and the circuit board between the carrier strips 6 is accurately placed in the housing of the communication device.

[0035] like Figure 4 , Figure 6 As shown, the bottom of the lifting plate 4 has an extrusion portion 41, and the thickness of the extrusion portion 41 is less than the thickness of the side of the lifting plate 4, so that a right-angle space for clamping the edge of the circuit board is formed on the inner side of the bottom of the lifting plate 4. When the extrusion portion 41 squeezes the carrier strip 6 downward to flip, the right-angle space simultaneously presses the edge of the circuit board downward, so that the positioning of the circuit board is more accurate. The inner side of the bottom end of the extrusion portion 41 is inclined, so that the thickness of the extrusion portion 41 gradually decreases from top to bottom, so that the extrusion portion 41 can be smoothly clamped on the edge of the circuit board.

[0036] like Figure 5 , Figure 6 As shown, a stop arm 42 extending downward is provided at one end of the lifting plate 4 close to the material guide conveyor belt 1, and the bottom of the stop arm 42 contacts the upper surface of the circuit board carried by the carrier strip 6. An end of the suspension 3 away from the material guide conveyor belt 1 has a right-angle arm 33 bent downward, and the right-angle arm 33 is used to block the circuit board carried by the carrier strip 6. A micro switch 34 for aligning the circuit board is provided on the surface of the right-angle arm 33, and the micro switch 34 is electrically connected to the electric push rod 31;

[0037] The circuit boards on the surface of the material-guiding conveyor belt 1 are conducted to the space between the movable plates 5 and supported by the carrier strips 6. The positions of the circuit boards are blocked by the right-angle arms 33 so that the circuit boards can be accurately positioned one by one. The micro switch 34 is activated only when it is touched by the circuit board and the electric push rod 31 extends downward to release the circuit board. When the circuit board is released downward, the blocking arm 42 descends to block the circuit boards on the surface of the material-guiding conveyor belt 1 from continuing to move forward, so that the circuit boards can enter and be assembled one by one between the movable plates 5.

[0038] like Figure 7 , Figure 8As shown, the resistance member 7 includes a slide 71, which slides on the outside of the movable plate 5. The slide 71 is positioned on the surface of the movable plate 5 by screws. A downwardly extending touch rod 72 is fixed on the surface of the slide 71. The bottom end of the touch rod 72 is lower than the carrier strip 6. The height of the slide 71 is adjusted by loosening the screws to adjust the bottom end height of the touch rod 72, and to adjust the timing of relative movement between the lifting plate 4 and the movable plate 5 to release the circuit board.

[0039] like Figure 1 , Fig. 9 As shown, the end of the guide conveyor belt 1 away from the suspension 3 is connected to the transverse moving assembly 2, and the transverse moving assembly 2 includes a straight shell 21, a sliding body 22 is slidably arranged in the straight shell 21, and the sliding body 22 is connected to the transverse moving conveyor belt through a carrier 25. A lead screw 23 is rotatably installed in the straight shell 21, and the lead screw 23 threadably penetrates the sliding body 22, and one end of the lead screw 23 is connected to a motor 24;

[0040] The motor 24 drives the lead screw 23 to rotate, so that the slide 22 drives the carrier 25 to move linearly, which is used to adjust the lateral position of the material guide conveyor belt 1, facilitate the loading of materials on the surface of the material guide conveyor belt 1 and adjust the position of the circuit board assembly station.
