[0018] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0019] like Figure 1-4 As shown, a PCBA board packing machine includes a machine base 1, and a first feeding conveyor 2, a second feeding conveyor 3, a bin transfer mechanism 4, a first discharging conveyor 5, a second discharging conveyor 6, and a picking and placing robot 7, all disposed on the machine base 1. The first feeding conveyor 2, the second feeding conveyor 3, the bin transfer mechanism 4, the first discharging conveyor 5, and the second discharging conveyor 6 are arranged sequentially in a U-shape along the bin conveying direction. The bin transfer mechanism 4 is used to transfer the bins from the second feeding conveyor 3 to the first discharging conveyor 5. The picking and placing robot 7 is located on the side of the bin transfer mechanism 4 away from the second feeding conveyor 3, and is used to pick up PCBA boards and load them into the bins of the first discharging conveyor 5.

[0020] When this case packing machine is used in conjunction with a PCBA depaneling machine, the board loading / unloading robot 7 is located near the PCBA board output port of the PCBA depaneling machine. The material bins are sequentially conveyed along the first feeding conveyor 2 and the second feeding conveyor 3. The material bin transfer mechanism 4 transfers the material bins from the second feeding conveyor 3 to the first discharging conveyor 5. Then, the board loading / unloading robot 7 picks up PCBA boards from the PCBA board output port of the PCBA depaneling machine and loads them into the material bins of the first discharging conveyor 5. Once the material bins are full, they are discharged via the first discharging conveyor 5 and the second discharging conveyor 6. This design helps save manpower and reduce labor intensity. In addition, the first feeding conveyor 2, the second feeding conveyor 3, the material bin transfer mechanism 4, the first discharging conveyor 5, and the second discharging conveyor 6 are arranged in a U-shape along the material bin conveying direction, which helps to make reasonable use of space and avoids the need for a longer overall case packing machine due to a linear distribution. It also facilitates centralized loading and unloading of material bins.

[0021] Furthermore, the material box transfer mechanism 4 includes a gantry frame 41 fixedly connected to the machine base 1, a linear module 42 fixedly connected to the top of the gantry frame 41, a connecting seat 43 fixedly connected to the output end of the linear module 42, a first guide rod cylinder 44 fixedly connected to the end of the connecting seat 43 away from the linear module 42, and a clamping assembly 45 connected to the output end of the first guide rod cylinder 44. The clamping assembly 45 is used to clamp the material box. Further still, the clamping assembly 45 includes a clamping seat 451 fixedly connected to the output end of the first guide rod cylinder 44, two second guide rod cylinders 452 fixedly connected to both ends of the bottom of the clamping seat 451, and a first L-shaped clamping plate 453 fixedly connected to the output end of the second guide rod cylinders 452. The two first L-shaped clamping plates 453 are used together to limit the fit with the grooves on the front and rear sides of the material box.

[0022] Using the above technical solution, in actual use, the outer side of the material box has grooves on the front, back, left and right sides. Two second guide rod cylinders 452 drive two first L-shaped clamping plates 453 to clamp the grooves on the front and back sides of the material box. The first guide rod cylinder 44 drives the clamping assembly 45 to rise as a whole and detach the material box from the second feeding conveyor 3. The linear module 42 drives the connecting seat 43, which in turn drives the first guide rod cylinder 44 and the clamping assembly 45 to laterally transfer the material box to the top of the first discharging conveyor 5. Then, the first guide rod cylinder 44 drives the clamping assembly 45 to fall as a whole and press the material box against the first discharging conveyor 5. The second guide rod cylinder 452 drives the two first L-shaped clamping plates 453 to release the material box, thus realizing the lateral transfer of the material box.

[0023] Furthermore, the board handling robot 7 includes a fixed frame 71 fixedly connected to the machine base 1, a four-axis robot 72 fixedly connected to the top of the fixed frame 71, a 90° side-positioning cylinder 73 connected to the output end of the four-axis robot 72, and a finger cylinder 74 connected to the output end of the 90° side-positioning cylinder 73. The finger cylinder 74 is used to clamp the PCBA board. The 90° side-positioning cylinder 73 drives the finger cylinder 74 to rotate the PCBA board downwards by 90° after the finger cylinder 74 clamps the PCBA board. At this time, the PCBA board is in a vertical state, and the four-axis robot 72 vertically places the PCBA board into the material box.

[0024] Furthermore, the box packing machine also includes a limiting stop 9 fixedly connected to the machine base 1 and close to the discharge end of the second feeding conveyor 3. The limiting stop 9 is used to prevent the box from being output along the discharge end of the second feeding conveyor 3, and to prevent the box from being output along the discharge end of the second feeding conveyor 3 and thus unable to be transferred by the box transfer mechanism 4.

[0025] Furthermore, the box packing machine also includes a stacked box unloading mechanism 8 fixedly connected to the machine base 1 and located at the feeding end of the second feeding conveyor 3. The stacked box unloading mechanism 8 is used to unload the stacked boxes one by one to the discharge end of the second feeding conveyor 3.

[0026] Furthermore, the stacked bin unloading mechanism 8 includes two bin lifting mechanisms 81 fixedly connected to the machine base 1 and located on the left and right outer sides of the second feeding conveyor 3, and a bin jacking mechanism 82 fixedly connected to the inner side of the second feeding conveyor 3. The bin jacking mechanism 82 is used to lift the stacked bins and detach them from the second feeding conveyor 3. The two bin lifting mechanisms 81 cooperate to lift the second-to-last stacked bin and detach it from the last stacked bin.

[0027] Furthermore, the material box lifting mechanism 81 includes a lifting seat 811 fixedly connected to the machine base 1, a third guide rod cylinder 812 fixedly connected to one side of the lifting seat 811, a fourth guide rod cylinder 813 connected to the output end of the third guide rod cylinder 812, and a second L-shaped clamping plate 814 connected to the output end of the fourth guide rod cylinder 813. The two second L-shaped clamping plates 814 are used together to limit the fit with the left and right side grooves of the second to last stacked material boxes.

[0028] Furthermore, the hopper lifting mechanism 82 includes two lifting cylinders 821 fixedly connected to the left and right inner sides of the second feeding conveyor 3, and a top support plate 822 fixedly connected to the output end of the two lifting cylinders 821. The top support plate 822 is used to support the last stacked hopper.

[0029] The above technical solution can meet the requirement of feeding multiple stacked material boxes from the first feeding conveyor 2. When the stacked boxes are unloaded one by one by the stacked boxes unloading mechanism 8 to the discharge end of the second feeding conveyor 3, the two lifting cylinders 821 drive the top support plate 822 to support the last stacked box, so that the stacked boxes are lifted at the same time. Then, the two fourth guide rod cylinders 813 drive the two second L-shaped clamping plates 814 to clamp the left and right side grooves of the second to last stacked box. The third guide rod cylinder 812 drives the fourth guide rod cylinder 813 to lift the second L-shaped clamping plate 814 and the second to last stacked box, so that the stacked boxes above the second to last stacked box are lifted at the same time. At this time, the last stacked box is separated from the second feeding conveyor 3 and the second to last stacked box respectively. The two lifting cylinders 821 drive the top support plate 822 to descend and reset, so that the last stacked box abuts against the second feeding conveyor 3 and is transported by the second feeding conveyor 3 to the discharge end of the second feeding conveyor 3.

[0030] Furthermore, the case packing machine also includes a limiting cylinder 10 fixedly connected to the machine base 1 and close to the discharge end of the first discharge conveyor 5. The limiting cylinder 10 is used to limit the output of the case along the discharge end of the first discharge conveyor 5. The case packing machine also includes a case stacking mechanism 11 fixedly connected to the machine base 1 and located at the discharge end of the first discharge conveyor 5. The case stacking mechanism 11 is used to stack the cases one by one to the discharge end of the first discharge conveyor 5.

[0031] The purpose of the limiting cylinder 10 in adopting the above technical solution is to restrict the output of the material box along the discharge end of the first discharge conveyor 5 during the material box stacking process in cooperation with the material box stacking mechanism 11 and the first discharge conveyor 5. In addition, the structure of the material box stacking mechanism 11 is the same as that of the stacked material box unloading mechanism 8, but the loading and unloading process is reversed. The purpose of the stacked material box unloading mechanism 8 is to unload the material boxes one by one from bottom to top from the stacked material boxes, and the purpose of the material box stacking mechanism 11 is to stack the material boxes one by one from bottom to top. These will not be described in detail here.

[0032] In this embodiment, the first feeding conveyor 2, the second feeding conveyor 3, the first discharging conveyor 5, and the second discharging conveyor 6 are all double-row belt conveyors, which are existing technologies and will not be described in detail here. It is also necessary to ensure that the lengths of the second feeding conveyor 3 and the first discharging conveyor 5 are sufficient to accommodate two material boxes placed one in front of the other.

[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
