Referring to fig. 4, fig. 4 is a schematic cross-sectional view of a conveyor along a central axis of a driving roller according to a first embodiment of the present application. In the first embodiment, the above-described conveying apparatus 10 includes a plurality of conveying assemblies 13, and these conveying assemblies 13 are arranged at intervals in a vertical direction in multiple stages. Each of the transferring assemblies 13 includes a first driving roller set 137 and a second driving roller set 139, and the first driving roller set 137 and the second driving roller set 139 of each of the transferring assemblies 13 are disposed in parallel and aligned in a vertical direction. Wherein, the first transmission roller group 137 and the second transmission roller group 139 are formed by arranging a plurality of transmission rollers 131 side by side. That is, each of the conveying assemblies 13 includes two upper and lower driving roller sets, a conveying platform is formed between each two driving roller sets, and the first driving roller set 137 and the second driving roller set 139, which are aligned in parallel, interact to convey the PCB positioned on the surface of the second driving roller set 139. The plurality of conveying assemblies 13 are arranged in an aligned manner at intervals up and down to form a plurality of conveying platforms, and the plurality of conveying platforms can be used for placing the PCB; and when a plurality of conveying platforms operate simultaneously, can convey a plurality of PCB boards simultaneously, improved conveyer 10's conveying efficiency.

Wherein the card 15 is disposed between two adjacent driving rollers 131 in each of the conveying assemblies 13. That is, each card 15 is vertically arranged on the conveying assembly 13, and each card 15 is caught in the gap between the corresponding adjacent two driving rollers 131 of each conveying assembly 13.

Referring to fig. 2, the second portion 153 of each card 15 is provided with a plurality of through holes 17, and the plurality of through holes 17 are spaced apart from each other to allow the PCB board transferred by each transfer assembly 13 to pass through. Wherein the through holes 17 include an upper wall 171 and a lower wall 173 opposite to each other, and the plurality of through holes 17 are longitudinally spaced and aligned, it is understood that the number of through holes 17 on each card 15 may be specifically set according to the number of layers of the conveying assembly 13, and is not specifically limited herein.

The length L of the through hole 17 is greater than the length of the PCB to be transferred, and the height h of the through hole 17 is greater than the thickness of the PCB to be transferred, so that the PCB is prevented from interfering with the wall surface of the through hole 17 when passing through the through hole 17, for example, colliding or blocking. It is understood that, in order to make the transfer device 10 meet the requirements of different types and parameters of transferring workpieces, for example, the length L of the through hole 17 may be limited to be greater than or equal to the length of the driving roller 131, and the height h of the through hole 17 may be less than or equal to the spacing distance between the corresponding first driving roller set 137 and the second driving roller set 139, but is not limited thereto.

In order to facilitate the smooth transfer of the PCB board on each transfer unit 13, referring to fig. 4, the upper cutting plane 1391 of the second driving roller set 139 of each transfer unit 13 is aligned with the corresponding through hole 17. In this way, the upper tangent plane 1391 of the second driving roller set 139 (the plane formed by the upper tangent lines of each second driving roller set 139) is aligned with the through hole 17, that is, the conveying platform formed by the second driving roller set 139 in each conveying assembly 13 is aligned with the through hole 17, so as to avoid the problem that the card 15 forms a barrier on each conveying platform, which results in the PCB being unable to continue conveying and even causing the conveying jamming. It should be noted that the above-mentioned upper and lower are relative positions, and the upper and lower positions shown in fig. 4 are taken as examples, and are only used for distinguishing two transmission roller sets of each conveying assembly 13, and do not represent that the first transmission roller set 137 and the second transmission roller set 139 can only be arranged up and down in practical use. In practical use, the first driving roller set 137 and the second driving roller set 139 of each conveying assembly 13 are arranged in parallel or aligned, and may be arranged vertically or horizontally. As can be seen from the above description, the second driving roller set 139 needs to be aligned with the through hole 17 of the card 15 to facilitate the PCB passing; therefore, it can be understood that the second driving roller group 139 is a driving roller group for supporting the PCB, and is not limited to whether the second driving roller group 139 is located below.

Furthermore, the shielding member 1511 of the first portion 151 of each card 15 is higher than the upper end tangent plane 1371 of the first driving roller set 137 of the top-layer conveying assembly 13, that is, the top end face 157 of the card 15 is higher than the upper end tangent plane 1371 of the first driving roller set 137 of the top-layer conveying assembly 13, and the portion of the card 15 higher than the upper end tangent plane 1371 of the first driving roller set 137 can block the water washing liquid, so as to reduce the influence of the water washing liquid on the conveying device 10, further reduce the possibility of the occurrence of the card jamming of the PCB during the conveying process, and thus improve the conveying efficiency of the conveying device 10.

Specifically, the upper end tangent plane 1391 of the second driving roller set 139 of each transferring unit 13 is aligned with the lower wall surface 173 of the corresponding through hole 17 or the center line of the through hole 17. That is, the upper end tangent plane 1391 of the second driving roller group 139 of each transferring assembly 13 forms a nearly smooth plane with the lower wall surface 173 of the corresponding through hole 17 or the plane where the center line is located, so that the first driving roller group 137 and the second driving roller group 139 interact to enable the second driving roller group 139 to smoothly transfer the PCB. Like this, all can form a conveying platform between every transport assembly 13 and the card 15 to form a plurality of conveying platforms, can satisfy the demand that same conveyer 10 conveys a plurality of PCB boards simultaneously, and make a plurality of PCB boards can smoothly pass through-hole 17 of card 15 in a plurality of conveying platform transfer processes, avoid the card to form the cardboard phenomenon in the clearance and arouse the conveying stagnation, greatly improved conveyer 10's conveying efficiency. It will be appreciated that the number of transfer assemblies 13 and the number of through holes 17 in the card 15 may be limited as required by the application. For example, the transport assembly 13 is one and the card 15 is provided with a through hole 17, but not limited thereto.

Referring to fig. 5, fig. 5 is a schematic cross-sectional view of a conveying device along a central axis of a driving roller according to a second embodiment of the present disclosure. This second embodiment differs from the first embodiment described above only in that: the transfer assembly 13 is one. At this time, the transferring assembly 13 includes a first driving roller set 137 and a second driving roller set 139 aligned in parallel in the vertical direction, as shown in fig. 5. Each card 15 is provided with a through hole 17 and is clamped between two adjacent driving rollers 131 of the first driving roller set 137 and the second driving roller set 139. The upper tangent plane 1391 of the second driving roller group 139 is aligned with the through hole 17. The upper tangential plane 1371 of the first driving roller set 137 is lower than the shielding member 1511 of the card 15. At this time, the shielding member 1511 of the card 15 higher than the upper end tangent plane 1371 of the first driving roller set 137 can block the water washing liquid, so as to reduce the influence of the water washing liquid on the conveying device 10, further reduce the possibility of the card plate appearing in the conveying process of the PCB plate, and improve the conveying efficiency of the conveying device.

Specifically, as shown in fig. 5, the upper tangent plane 1391 of the second driving roller set 139 in the transport unit 13 is flush with the lower wall 173 or the center line of the through hole 17 in the card 15. That is, the second driving roller group 139 forms a nearly smooth plane due to the fact that the card reduces the gap between the driving rollers, and the through hole 17 is provided, so that the PCB can be smoothly passed through the through hole 17 of the card 15 when being conveyed on the conveying assembly 13, thereby avoiding the occurrence of the card jamming phenomenon.

The transfer assembly 13 of the present application is a row of drive roller sets formed by a plurality of drive rollers 131 side by side. That is, the transferring assembly 13 has only one driving roller set, compared to the second embodiment of the present application described above. In this case, each card 15 may be provided with one or no through-hole 17. When the card 15 is not provided with the through hole 17, as shown in fig. 6, the upper end cut plane 132 of the carrier assembly 13 is flush with the top end face 157 of the card 15; when the card 15 is provided with a through hole 17, as shown in fig. 7, the upper tangent plane 132 of the transmission assembly 13 is flush with the lower wall 173 or the plane of the center line of the through hole 17. That is, when the through hole 17 is provided in the card 15, the lower wall surface 173 of the through hole 17 forms a nearly smooth one plane with the upper end tangent plane 132 of the driving member 13, or when the through hole 17 is not provided in the card 15, the tip end surface 157 of the card 15 itself forms a nearly smooth one plane with the upper end tangent plane 132 of the driving member 13, thereby forming a transfer platform, enabling the PCB board to smoothly pass through when transferring.
