[0031] The utility model will be further explained in combination with the drawings and specific embodiments, so that the person skilled in the art can better understand the utility model and can be implemented, but the embodiment is not as the limitation of the utility model.
[0032] Reference Figures 1-5 The utility model embodiment provides a kind of conveying equipment for preventing PCB card board, it include: multiple roller sheet groups 100 and multiple solid roller groups 200.The two ends of conveying equipment are respectively provided with at least one solid roller group 200, then middle position is provided with multiple roller sheet groups 100.For example, along conveying direction V, rear end is provided with one solid roller group 200, middle position is provided with multiple roller sheet groups 100, and front end is provided with three solid roller groups 200.
[0033] Two roller sheet groups 100 and solid roller group 200 (i.e. in front end position, the position of the two roller sheet groups 100 and solid roller group 200 that roller sheet group 100 and solid roller group 200 link), along conveying direction V sequentially set;Roller sheet group 100 includes first spindle 110 and multiple first rollers 120 that are spaced apart on first spindle 110;The first roller 120 of two roller sheet groups 100 is staggered arrangement;Solid roller group 200 includes second spindle 210 and multiple second rollers 220 that are spaced apart on second spindle 210;
[0034] Multiple bridges 300 are provided with two through holes 310, two through holes 310 are respectively sleeved on the first spindle 110 of two roller sheet groups 100, and bridge 300 is located between adjacent two first rollers 120 in roller sheet group 100;The top of the front end of bridge 300 is provided with the protrusion 320 that extends to second roller 220, and the front end face of protrusion 320 avoids second roller 220.
[0035] Specifically, the application connects the bridge 300 on two roller piece groups 100 adjacent to the solid roller group 200, and then the protrusion 320 of the bridge 300 extends to the second roller 220, so that when the PCB board 600 is conveyed to the position where the roller piece group 100 and the solid roller group 200 are connected, the PCB board 600 will enter the second roller 220 under the guidance of the bridge 300, thereby preventing the PCB board from falling off and being stuck.
[0036] Further, a plurality of bridge groups are arranged along the length direction of the first main shaft 110. At least three bridge groups are arranged below each PCB board 600. Each bridge group includes at least one bridge 300. In some bridge groups, two bridges 300 are included, and in other bridge groups, one bridge 300 is included. For example, the bridge groups on both sides of the PCB board 600 include two bridges 300, and the bridge group at the middle position of the PCB board 600 includes one bridge 300. In this way, the support is improved, and the cost is reduced. Specifically, the PCB board 600 is supported by the plurality of bridge groups, which further avoids deformation of the PCB board 600, thereby providing smooth conveying.
[0037] Further, the application also includes a sleeve 400, which is sleeved between the first main shaft 110 and the bridge 300.
[0038] Specifically, since the first main shaft 110 drives the first roller 120 to rotate synchronously, if the bridge 300 is directly sleeved on the first main shaft 110, the bridge 300 will be greatly worn, which affects the service life of the bridge 300. Therefore, the sleeve 400 is used to separate the first main shaft 110 and the bridge 300 in the embodiment, thereby reducing the wear of the bridge 300 and improving the service life of the bridge 300.
[0039] Further, the application also includes a limiting ring 500; one end of the sleeve 400 is provided with a head 410; the limiting ring 500 is detachably connected to the other end of the sleeve 400; and the bridge 300 is located between the limiting ring 500 and the head 410.
[0040] Specifically, the bridge 300 is limited between the limiting ring 500 and the head 410 by the limiting ring 500 and the head 410, thereby avoiding large-scale movement of the bridge 300 along the axis direction of the first main shaft 110.
[0041] Further, the limiting ring 500 is threadedly connected with the sleeve 400.
[0042] Specifically, the detachable connection between the limiting ring 500 and the sleeve 400 is achieved by screwing, which facilitates the installation and dismounting of the two. On the other hand, the position of the bridge 300 can be adjusted by the depth of the limiting ring 500 screwed into the sleeve 400, which facilitates the control of the range of the axial movement of the bridge 300 along the first main shaft 110, so that the bridge 300 can be installed on any roller piece set 100.
[0043] Further, the front end surface of the protrusion 320 is a circular arc 330, which has the same shape as the outer wall of the second roller 220 and has a gap therebetween. Specifically, the circular arc 330 of the present embodiment has the same shape as the outer wall of the second roller 220, so that the protrusion 320 and the second roller 220 can be more easily avoided.
[0044] Further, the gap is 1.5 mm.
[0045] Further, the front end circular arc of the protrusion 320 is a transition 340. Specifically, the present embodiment avoids the protrusion 320 having a sharp corner, so that the PCB board 600 will not be damaged.
[0046] Further, the distance between the upper surface of the bridge 300 and the lower surface of the PCB board 600 is 0.5-3 mm.
[0047] Specifically, the distance achieves the amount of sag of the PCB board 600 and avoids being too large to facilitate the transition of the first roller 120 to the second roller 220. Thus, the present embodiment can better achieve the transition of the first roller 120 to the second roller 220, so as to further reduce the carding phenomenon.
[0048] Obviously, the above embodiments are only examples for clear illustration, and are not intended to limit the embodiments. For those skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the embodiments need not and cannot be exhausted. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
