[0040] It can be understood that by placing the PCB substrate 70 on the bearing assembly 30, and then by moving a plurality of side limiting assemblies 40 on the bearing assembly 30, so that the plurality of side limiting assemblies 40 can support the side of the PCB substrate 70, the PCB substrate 70 can be stably set on the bearing assembly 30, and then a plurality of groups of upper limiting assemblies 60 are used to support the upper surface of the PCB substrate 70, not only the purpose of further limiting the PCB substrate 70 is achieved, but also the PCB substrate 70 can be prevented from bouncing due to bumps during transportation, so that the PCB substrate 70 can be further transported stably. In addition, the carrying frame 31 frame 10 is driven by the walking assembly 20, so that the PCB substrate 70 can be transported. In this embodiment, the walking assembly 20 includes a plurality of groups of universal wheels 21, and the plurality of groups of the universal wheels 21 are evenly connected to the bottom of the carrying frame 31 frame 10. The universal wheels 21 drive the carrying frame 31 frame 10, and the carrying frame 31 frame 10 drives a plurality of bearing assemblies 30, so that the carrying assembly 30 can drive the PCB substrate 70 for transportation.

[0041] In addition, a handle 11 is connected to one side of the carrying frame 31 frame 10. By pulling the handle 11 by a staff member, the carrying frame 31 frame 10 can be moved through the universal wheel 21.

[0042] Specifically, in this embodiment, the bearing assembly 30 includes a bearing frame 31, a plurality of longitudinal bearing steel wires 32 and a plurality of transverse bearing steel wires 33, wherein the plurality of longitudinal bearing steel wires 32 are evenly arranged in the bearing frame 31, and the plurality of transverse bearing steel wires 33 are evenly arranged in the bearing frame 31 and are perpendicular to the longitudinal bearing steel wires 32.

[0043] It needs to be explained that a plurality of longitudinal load-bearing steel wires 32 and a plurality of transverse load-bearing steel wires 33 are vertically staggered in the bearing frame 31, so that the bearing frame 31 can carry the PCB substrate 70 through the longitudinal load-bearing steel wires 32 and the transverse load-bearing steel wires 33, and the staggered longitudinal load-bearing steel wires 32 and the transverse load-bearing steel wires 33 can not only support the PCB substrate 70, but also dissipate the heat of the PCB substrate 70 after baking.

[0044] In addition, in this embodiment, the side limit assembly 40 includes an abutment block 41, two support blocks 42 and a screw 43, the abutment block 41 is slidably arranged on the bearing assembly 30, the two support blocks 42 are symmetrically arranged on both sides of the abutment block 41, and the two support blocks 42 are slidably arranged on the bearing assembly 30, the screw 43 is arranged on the upper surface of the abutment block 41, and a sponge pad 44 is provided on one side of the abutment block 41 close to the PCB substrate 70.

[0045] It can be understood that the abutment block 41 is slidably set on the transverse load-bearing steel wire 33, the two support blocks 42 are set on the transverse load-bearing steel wires 33 adjacent to the abutment block 41, and the two support blocks 42 are connected to the two side walls of the abutment block 41 to prevent the abutment block 41 from rotating on the transverse load-bearing steel wire 33, so that the abutment block 41 can be stably set on the transverse load-bearing steel wire 33. In specific implementation, the abutment block 41 is moved so that the sponge pad 44 on the side of the abutment block 41 abuts against the two ends of the PCB substrate 70, and then the screw 43 is rotated so that the screw 43 abuts the abutment block 41 on the transverse load-bearing steel wire 33, so that the abutment block 41 can stably abut the side of the PCB substrate 70.

[0046] It is worth noting that, through a plurality of groups of abutment blocks 41, PCB substrates 70 of different sizes can be abutted, thereby improving the applicability of bearing.

[0047] Specifically, in this embodiment, the mounting assembly 50 includes two mounting plates 51, and the two mounting plates 51 are symmetrically arranged on both sides of the upper surface of the bearing assembly 30. A movable groove 52 is opened on the two mounting plates 51, and the upper limit assembly 60 is arranged in the movable groove 52. The upper limit assembly 60 includes a connecting rod 61 and a plurality of sponge blocks 62. Both ends of the connecting rod 61 are arranged on the mounting assembly 50, and a plurality of sponge blocks 62 are evenly arranged on the connecting rod 61. Both ends of the connecting rod 61 are connected to a limiting block, and the limiting block abuts against the outer wall of the mounting assembly 50.

[0048] It needs to be explained that the two ends of the connecting rod 61 are respectively arranged in the movable grooves 52 of the two mounting plates 51, and the limit blocks are fixedly connected to the two ends of the connecting rod 61 and are arranged on the outer wall of the mounting plate 51 to prevent the connecting rod 61 from falling out of the movable groove 52, and the sliding friction of the connecting rod 61 in the movable groove 52 is relatively large, so the connecting rod 61 can be pushed manually, and the connecting rod 61 is stably set in the movable groove 52 by its own friction, and the connecting rod 61 is moved to the top of the PCB substrate 70, and then the sponge block 62 is pressed against the upper surface of the PCB substrate 70, so that the sponge block 62 can press against the upper surface of the PCB substrate 70, so that the PCB substrate 70 can be stably set in the supporting frame 31.

[0049] In summary, the PCB substrate 70 transfer vehicle in the above embodiment of the utility model places the PCB substrate 70 on the carrying assembly 30, and then limits the two ends of the PCB substrate 70 through the side limit assembly 40 to prevent the PCB substrate 70 from shaking on the carrying assembly 30 during transportation, and effectively prevents the PCB substrates 70 from colliding with each other. The upper limit assembly 60 can not only limit the upper part of the PCB substrate 70 to prevent the PCB substrate 70 from jumping up and down due to shaking, but also can further support the PCB substrate 70, so that the PCB substrate 70 can be stably transported, effectively preventing damage caused during transportation.
