After the circuit board assembly 20 comes out of the unloading port 29 of the mounter 200, it can be transmitted to the conveying device 12 through the feeding port 16. When the circuit board assembly 20 is located on the conveying device 12, the conveying device 100 can control the driving assembly 14 to drive the conveying device 12 to move from the feeding port 16 to the discharging port 18. The conveying device 12 can transmit the circuit board assembly 20 to the reflow oven 300 through the discharging port 18. In one embodiment, after the circuit board assembly 20 on the conveying device 12 is transmitted to the reflow oven 300, the conveying device 100 can control the driving assembly 14 to drive the conveying device 12 to move from the discharging port 18 to the feeding port 16.

The driving assembly 14 is configured to drive the first conveying device 26 to move between the first feeding port 30 and the discharging port 18, and drive the second conveying device 28 to move between the second feeding port 32, the third feeding port 34 and the discharging port 18.

[0044] In this way, the circuit board assemblies 20 processed by multiple mounters 200 can be respectively transmitted to the first conveying device 26 and the second conveying device 28 through the first feeding port 30, the second feeding port 32 and the third feeding port 34, improving the efficiency of feeding the circuit board assembly 20 into the reflow oven 300.

[0045] Specifically, in Figure 2 , the three mounters 200 are respectively a first mounter 201, a second mounter 202 and a third mounter 203. The three mounters 200 can transmit the processed circuit board assemblies 20 to the conveying device 100, and the first conveying device 26 and the second conveying device 28 in the chassis 10 can convey the circuit board assemblies 20 to the reflow oven 300. The first conveying device 26 and the second conveying device 28 are symmetrically arranged in the chassis 10, and the structures of the first conveying device 26 and the second conveying device 28 are basically the same. In Figure 1Among them, the first feed inlet 30, the second feed inlet 32, and the third feed inlet 34 are sequentially and spacedly arranged along the L direction on the side wall of the upper box body 22.

[0046] In addition, the multiple loading signals include a first loading signal, a second loading signal, and a third loading signal. The first mounter 201 emits the first loading signal, the second mounter 202 emits the second loading signal, and the third mounter 203 emits the third loading signal.

[0047] In one embodiment, the first mounter 201 emits the first loading signal.

The circuit board assembly 20 processed by the second mounter 202 can be transmitted to the second conveying device 28 through the second feed inlet 32. The driving assembly 14 can drive the second conveying device 28 to move from the second feed inlet 32 to the discharge port 18 or drive the second conveying device 28 to move from the discharge port 18 to the second feed inlet 32.

[0049] In one embodiment, the third mounter 203 emits the third loading signal.

[0050] It should be noted that the first conveying device 26 can convey the circuit board assembly 20 alone, the second conveying device 28 can convey the circuit board assembly 20 alone, and the first conveying device 26 and the second conveying device 28 can convey the circuit board assembly 20 simultaneously. In addition, when conveying the circuit board assembly 20 of the second mounter 202 and the circuit board assembly 20 of the third mounter 203, the second loading signal takes precedence over the third loading signal. The second conveying device 28 preferentially conveys the circuit board assembly 20 of the second mounter 202, then conveys the circuit board assembly 20 of the third mounter 203, and then reciprocates in a cycle.

[0051] It can be understood that in other embodiments, the first conveying device 26 can also convey the circuit board assemblies 20 of two mounters 200. For details, reference can be made to the second conveying device 28.

[0052] In addition, in combination with Figure 2 and Figure 3 , the reflow oven 300 includes a double-track reflow oven.

In one example, after the second conveying device 28 moves from the second feed port 32 to the discharge port 18, the second conveying device 28 can convey the circuit board assembly 20 to the second transfer track 302 through the discharge port 18. In one example, after the second conveying device 28 moves from the third feed port 34 to the discharge port 18, the second conveying device 28 can convey the circuit board assembly 20 to the second transfer track 302 through the discharge port 18.

[0053] Please refer to Figures 4 to 7 , in some embodiments, the conveying device 12 includes a frame 47, a conveyor belt 48 and a driving motor 50. The conveyor belt 48 is rotatably connected to the frame 47. The driving motor 50 is fixedly connected inside the frame 47 and is rotatably connected to the conveyor belt 48 to drive the conveyor belt 48 to rotate.

In one embodiment, when the circuit board assembly 20 is conveyed from the blanking port 29 to the conveyor belt 48 through the feeding port 16, the driving motor 50 can drive the driving wheel 60 to rotate, and the driving wheel 60 drives the conveyor belt 48 to rotate, so that the circuit board assembly 20 can move on the conveyor belt 48 in a direction away from the feeding port 16.

[0057] It should be noted that the conveyor belts 48 on the first frame 52 and the second frame 54 jointly carry the circuit board assembly 20. The circuit board assembly 20 can be driven to move by the synchronous rotation of the conveyor belts 48 on the first frame 52 and the second frame 54.

[0058] Please refer to Figures 4 to 6 , in some embodiments, the conveying device 12 includes a board output signal device 64 and a board stop signal device 66. The board output signal device 64 is arranged at one end of the frame 47, and the board stop signal device 66 is arranged at the other end of the frame 47.

The board stop signal device 66 is configured to stop the driving motor 50 from driving the conveyor belt 48 when detecting the circuit board assembly 20.

[0059] In this way, the start and stop of the driving motor 50 are controlled by the board output signal device 64 and the board stop signal device 66, and further the movement and stop of the circuit board assembly 20 on the conveyor belt 48 are controlled.

[0060] Specifically, the conveying device 12 includes a first bracket 68 and a second bracket 70. The first bracket 68 is fixedly connected to one end of the mounting part 56 close to the feeding port 16, and the second bracket 70 is fixedly connected to the other end of the mounting part 56 away from the feeding port 16. The board input signal device is connected to the first bracket 68 and is located above the conveyor belt 48. The board stop signal device 66 is connected to the second bracket 70 and is located above the conveyor belt 48.

[0061] In one embodiment, the circuit board assembly 20 is conveyed onto the conveyor belt 48 through the feed inlet 16. The circuit board assembly 20 is located below the board output signal device 64. When the board output signal device 64 detects the circuit board assembly 20, it causes the drive motor 50 to drive the conveyor belt 48 to rotate, driving the circuit board assembly 20 to move from one end of the mounting portion 56 to the other end of the mounting portion 56. When the circuit board assembly 20 moves below the board stop signal device 66, when the board stop signal device 66 detects the circuit board assembly 20, it causes the drive motor 50 to stop driving the conveyor belt 48, and the circuit board assembly 20 stops moving.
