[0015] 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.

[0016] like Figure 1-4 As shown, a PCBA box conveying mechanism includes a machine base 1 and two symmetrically arranged box conveyor units on the top of the machine base 1. Each box conveyor unit includes a belt conveyor 2 fixedly connected to the top of the machine base 1, a stacked box unloading device 3 fixedly connected to the outside of the machine base 1 and close to the box input end of the belt conveyor 2, and a box positioning component 4 fixedly connected to the outside of the machine base 1 and close to the middle of the belt conveyor 2. The belt conveyor 2 and the stacked box unloading device 3 cooperate to unload the stacked boxes one by one to the middle of the belt conveyor 2. The box positioning component 4 is used to intercept and position the boxes.

[0017] The PCBA box conveying mechanism employs a machine base 1 and two symmetrically arranged box conveyor units on top of the machine base 1. Each box conveyor unit includes a belt conveyor 2 fixedly connected to the top of the machine base 1, a stacked box unloading device 3 fixedly connected to the outside of the machine base 1 and near the box input end of the belt conveyor 2, and a box positioning component 4 fixedly connected to the outside of the machine base 1 and near the middle of the belt conveyor 2. In actual use, after the boxes are stacked at the input end of the belt conveyor 2, the belt conveyor 2 and the stacked box unloading device 3 work together to unload the stacked boxes one by one towards the middle of the belt conveyor 2. At the same time, the box positioning component 4 intercepts and positions the boxes so that PCBA boards can be loaded into the boxes. The boxes filled with PCBA boards are then transported to the next process by the belt conveyor 2, which helps to save manpower and reduce labor intensity.

[0018] Furthermore, the stacked bin unloading device 3 includes a bin lifting drive assembly 31 fixedly connected to the outside of the machine base 1 and close to the bin input end of the belt conveyor 2, and a bin clamping assembly 32 fixedly connected to the output end of the bin lifting drive assembly 31. The bin lifting drive assembly 31 and the bin clamping assembly 32 cooperate to lift the second to last stacked bin and detach it from the first to last stacked bin. When the belt conveyor 2 and the stacked bin unloading device 3 work together to unload the stacked bins one by one to the middle of the belt conveyor 2, the bin lifting drive component 31 and the bin clamping component 32 work together to lift the second-to-last bin and detach it from the first-to-last bin. The stacked bins above the second-to-last bin are simultaneously lifted. At this time, the belt conveyor 2 operates to transport the first-to-last bin to the middle of the belt conveyor 2 until it is intercepted by the bin positioning component 4. Then, the bin lifting drive component 31 and the bin clamping component 32 work together to lower the second-to-last bin onto the belt conveyor 2, completing one bin unloading process.

[0019] Furthermore, the hopper lifting drive assembly 31 includes a side support 311 fixedly connected to the outside of the machine base 1 and near the hopper input end of the belt conveyor 2, and a Z-axis lead screw module 312 fixedly connected to the side support 311. The output end of the Z-axis lead screw module 312 is fixedly connected to the hopper clamping assembly 32. The Z-axis lead screw module 312 is prior art and is only used here as an application to drive the hopper clamping assembly 32 to lift and lower.

[0020] Furthermore, the hopper clamping assembly 32 includes a T-shaped support plate 321 fixedly connected to the output end of the hopper lifting drive assembly 31, and two clamping arm assemblies 322 fixedly connected to both ends of the T-shaped support plate 321. The two clamping arm assemblies 322 cooperate to clamp the hopper.

[0021] Furthermore, the clamping arm assembly 322 includes a first guide rod cylinder 3221 fixedly connected to the T-shaped support plate 321, a clamping arm 3222 fixedly connected to the output end of the first guide rod cylinder 3221, a Y-guide rail 3223 fixedly connected to one end of the T-shaped support plate 321, and a slider 3224 slidably connected to the Y-guide rail 3223 and fixedly connected to the clamping arm 3222. A protrusion 5 is fixedly connected to the top of the clamping arm 3222. The protrusions 5 of the two clamping arm assemblies 322 are used together to limit the engagement with the grooves on the front and rear sides of the material box. It should be noted that the material box clamped in this solution has grooves on its outer side (front, back, left, and right). By using the protrusions 5 of the two clamping arm assemblies 322 to limit the engagement with the grooves on the front and rear sides of the material box, when the material box is lifted, the two clamping arms 3222 clamp the material box while the protrusions 5 abut against the grooves vertically, preventing the material box from loosening and slipping.

[0022] Furthermore, the material box positioning assembly 4 includes a first cylinder seat 41 fixedly connected to the outside of the machine base 1 and near the middle of the belt conveyor 2, a second guide rod cylinder 42 fixedly connected to the first cylinder seat 41, a side top plate 43 fixedly connected to the output end of the second guide rod cylinder 42, a second cylinder seat 44 fixedly connected to the outside of the machine base 1 and near the middle end of the belt conveyor 2, a third guide rod cylinder 45 fixedly connected to the second cylinder seat 44, and a limiting stop bar 46 fixedly connected to the output end of the third guide rod cylinder 45. The side top plate 43 is used to limit the material box with an outer groove, and the limiting stop bar 46 is used to prevent the material box from being output to the discharge end of the belt conveyor 2. In use, the third guide rod cylinder 45 drives the limit stop 46 to descend to prevent the material box from being output to the discharge end of the belt conveyor 2. Then, the second guide rod cylinder 42 drives the side top plate 43 to cooperate with the outer groove of the material box for limiting. At this time, the position of the material box is the target position referred to in the background art. Moreover, the material box positioning component 4 intercepts and positions the material box, which helps to avoid the material box being misplaced.

[0023] Furthermore, the PCBA bin conveying mechanism also includes a barcode reader unit 6 fixedly connected to both sides of the machine base 1. The barcode reader unit 6 includes a gantry frame 61 fixedly connected to both sides of the machine base 1, an X-axis linear module 62 fixedly connected to the gantry frame 61, a connecting arm 63 fixedly connected to the output end of the X-axis linear module 62, and an industrial barcode reader 64 fixedly connected to the connecting arm 63. The industrial barcode reader 64 is used to read the identification code on the front end of the bin. The X-axis linear module 62 is existing technology and is used to drive the connecting arm 63 to move in the X direction; it is only used as an example here. The industrial barcode reader 64 is existing technology, such as the Hikvision MV-ID2016M, and is used to read the identification code on the front end of the bin; it is only used as an example here.
