[0019] Furthermore, such as Figure 4 , Figure 5 and Figure 7 As shown, the surfaces of the assembly frame 118 and the material handling rack 120 are provided with a precision assembly mechanism 3. The precision assembly mechanism 3 consists of a first vision sensor 31, an assembly rack plate 32, a second vision sensor 33, and a pressure sensor 34. Two sets of assembly rack plates 32 are symmetrically installed on the surface of the assembly frame 118 by screws. The first vision sensor 31 is installed on the surface of the assembly rack plate 32. The first vision sensor 31 can be a PHA series sensor.

[0020] During implementation, the assembly position of the bottom shell 121 and the PCB is photographed and positioned by the first vision sensor 31 on the surface of the assembly rack 32. The position of the bottom shell 121 clamped by the pick-up rack 120 is photographed by the second vision sensor 33, and the results are sent to the controller 11 so that the bottom shell 121 can be accurately placed at the designated position on the surface of the assembly loading device 113. When the pick-up rack 120 places the clamped PCB on the surface of the bottom shell 121, the pressure sensor 34 can monitor the pressure when the pick-up rack 120 places the PCB to avoid excessive pressure from damaging the PCB board, so as to realize the function of precise assembly of the loading assembly equipment.
[0021] Working Principle: In use, the equipment frame 1 is first placed in the designated position. An external robotic arm places the tray 111 containing the bottom shell body 121 to be assembled in designated positions on the operating table 10. The PCB to be assembled is transported to the designated position via the PCB loading module 112. The controller 11 controls the first forward and backward movement module 16 on the surface of the second fixed frame 14. Under the action of the first forward and backward movement module 16, the second picking robotic arm 115 moves back and forth, gripping and picking up the bottom shell body 121 from the tray 111. At this time, the controller 11 controls the second belt conveyor module 117 to operate. Under the action of the second belt conveyor module 117, the PCB is transported by the empty assembly loading device 113, without stopping the loading mechanism 2. Under the action of the loading mechanism 2, the loading assembly 113 moves through the trough 116 to one side of the PCB loading module 112. The non-stop loading mechanism 2 drives the loading assembly 113 to move to the surface of the PCB loading module 112. Under the action of the PCB loading module 112, the loading assembly 113 is transported to the designated position. The second picking robot 115 places the bottom shell body 121 that has been taken out into the designated position on the surface of the loading assembly 113. Then, the second picking robot 115 picks up the PCB board transported on the surface of the PCB loading module 112 and places it on the surface of the bottom shell body 121 on the surface of the loading assembly 113 to position the bottom shell body 121 and the PCB. After the bottom shell body 121 and the PCB are positioned, the third conveyor... Under the action of component 123, the assembly loading device 113 is conveyed. The robot removes the bottom shell body 121 and PCB from the surface of the assembly loading device 113 for the next operation. The empty assembly loading device 113 is conveyed to the surface of the second belt conveyor module 117 for uninterrupted feeding, so that the bottom shell body 121 and PCB do not need to be replaced during assembly without stopping the machine. Subsequently, under the action of the second forward and backward moving module 17, the first picking robot 114 moves to feed the bottom shell body 121 placed on the surface of the loading tray 111 to the surface of the assembly loading device 113, and the feeding is carried out alternately. When the loading tray 111 is empty, the second picking robot 115 and the first picking robot 114 place the loading tray 111 on the first belt conveyor module. The surface of the assembly frame 118, i.e., the position of the empty tray 18, is then moved left and right by the left and right moving module 15 to the required position. The second forward and backward moving module 17 moves the moving frame 102 to the required position on the surface of the second fixed frame 14, precisely picking up material from the bottom shell 121 on the surface of the tray 111. When the laser positioning sensor 119 senses that the assembly frame 118 has moved to the required position, it sends a signal to the controller 11. Upon receiving the signal from the laser positioning sensor 119, the controller 11 automatically controls the cylinder 122 on the surface of the assembly frame 118 to operate, causing the picking frame 120 to move downwards.Under the action of the picking rack 120, the bottom shell body 121 is clamped. Then, when the picking rack 120 moves the bottom shell body 121 to a designated position above the assembly loading fixture 113, the controller 11 controls the cylinder 122 to operate. Under the action of the cylinder 122, the picking rack 120 and the bottom shell body 121 move downwards, placing the bottom shell body 121 on the surface of the assembly loading fixture 113. Then, the picking rack 120 clamps the PCB board on the surface of the PCB loading module 112, placing the PCB on the surface of the bottom shell body 121, aligning and assembling the bottom shell body 121 and the PCB.
[0022] Subsequently, the assembly position of the bottom shell 121 and the PCB is photographed and positioned by the first vision sensor 31 on the surface of the assembly rack 32, and the position of the bottom shell 121 clamped by the pick-up rack 120 is photographed by the second vision sensor 33. The results are sent to the controller 11 so that the bottom shell 121 can be accurately placed at the designated position on the surface of the assembly loading device 113. When the pick-up rack 120 places the clamped PCB on the surface of the bottom shell 121, the pressure sensor 34 can monitor the pressure when the pick-up rack 120 places the PCB to avoid excessive pressure from damaging the PCB board. This achieves the function of precise assembly of the loading assembly equipment, so that the loading assembly equipment can ensure the accuracy of the assembly between the PCB and the bottom shell when in use, and make the assembly effect between the PCB and the bottom shell better when the loading assembly equipment is in use.
[0023] Subsequently, when the second belt conveyor module 117 conveys the empty assembly 113 to the surface of the conveyor assembly body 21 on the surface of the conveyor rack 22, the controller 11 controls the electric push rod 23 on the surface of the base plate 101 to work. Under the action of the electric push rod 23, the support frame plate 24, the conveyor rack 22, and the conveyor assembly body 21 move upward. At this time, the conveyor rack 22, the support frame plate 24, and the conveyor assembly body 21 pass through the trough 116 and move to the top of the operating table 10. At this time, the conveyor rack 22 is level with the position of the third conveyor assembly 123. The controller 11 controls... The conveying component body 21 operates, conveying the assembly loading fixture 113 placed on the surface of the conveying component body 21. The empty assembly loading fixture 113 is conveyed to the surface of the third conveying component 123, and the bottom shell body 121 and PCB are assembled for the next time. This realizes the function of the loading assembly equipment to load the assembly loading fixture 113 without stopping the machine. As a result, the loading assembly equipment does not need to stop to load the assembly loading fixture 113 during use, making the processing efficiency of the loading assembly equipment higher during use, and finally completing the use of the loading assembly equipment.
