[0039] The end of the second mechanical arm is equipped with a fixed seat 31 and a back plate grabbing device 32 for grabbing the back plate 20 and an iron cover grabbing device 33 for grabbing the iron cover 30. The second mechanical arm drives the back plate grabbing device to move the back plate to the locking position and drives the iron cover grabbing device to move the iron cover to the locking position. The fixed seat is provided with a second visual inspection unit 34.

[0040] A locking device 41 is installed at the end of the third mechanical arm; the locking device is driven by the third mechanical arm to lock the pressure rod, the back plate, the iron cover and the PCBA together; a third visual inspection unit 42 is provided at the locking device.

[0041] In this embodiment, the PCBA is conveyed to the locking station via a conveyor belt 6 .

[0042] In this embodiment, Figure 2 As shown, the pressure rod material taking device 21 includes a group of clamping jaws 211, a clamping jaw cylinder 212 and a clamping jaw lifting driving cylinder 213 capable of driving the clamping jaws to rise and fall, the clamping jaw cylinder is installed at the end of the clamping jaw lifting driving cylinder, and a group of clamping jaws is installed at the end of the clamping jaw cylinder. The clamping jaws are driven to open or close by the clamping jaw cylinder to achieve clamping or loosening of the clamping jaws.

[0043] like Figure 2As shown, a group of jaws are provided on each side of the pressure bar picking device, which are defined as the first group of jaws and the second group of jaws, respectively, wherein the first group of jaws is used to grab the pressure bar in the first state, and the second group of jaws is used to grab the pressure bar in the second state. The specific process is: the first group of jaws is used to grab the pressure bar in the first state, the first mechanical arm drives the first group of jaws to rotate to a suitable angle and position, and then places it on the transfer platform (not shown in the figure), and then the second group of jaws is used to grab the pressure bar in the second state, and then the second mechanical arm drives it to the locking position. The loading of the pressure bar can also be tray-type loading, which is not shown in the figure, but is not limited to this, and other methods are also possible.

[0044] like Figure 3 As shown, the back panel grabbing device 32 includes a back panel suction component 321 and a back panel lifting drive cylinder 322. The back panel lifting drive cylinder is installed on the fixed seat, and the back panel suction component is installed on the power output end of the back panel lifting drive cylinder.

That is, the problem of single poor removal and adsorption can be solved by two methods; magnet adsorption is used at the side piece, and the space occupied is too small. If a suction cup is used, the space is limited and it cannot be put down.

There are many structures of the loading area, such as placing the tray, then moving the tray to a suitable position through a handling module, and then the second robot arm is in place to drive the back plate grabbing device to grab the back plate, and drive the iron cover grabbing device to grab the iron cover, but it is not limited to this.

[0052] In this embodiment, the first robotic arm and the second robotic arm are six-axis robotic arms; the third robotic arm is a four-axis robotic arm.

[0053] The working process and working principle of the utility model are as follows:

[0054] The PCBA (including the carrier) is transported to the locking station via a conveyor belt (it can be placed on the carrier of the locking station through other structures). Of course, the carrier with the PCBA can also be placed directly at the locking station manually.

[0055] Guided by the second visual inspection unit, the second robotic arm drives the backboard grabbing device to the loading area to pick up the material, and moves the backboard to the locking station;

The first robot arm drives the first group of grippers to rotate to a suitable angle and position, and then places it on the transfer platform (not shown in the figure), and then the second group of grippers is used to grab the pressure bar in the second state, and then the second robot arm drives it to the locking station;

[0057] Under the guidance of the third visual inspection unit, the third mechanical arm drives the locking device to absorb the screw and lock it;

[0058] Guided by the second visual inspection unit, the second robotic arm drives the iron cover grasping device to the loading area to pick up the material, and moves the iron cover to the locking station; under the guidance of the third visual inspection unit, the third robotic arm drives the locking device again to absorb the screws and lock them.
