[0033] Referring to Figure 1 and Figure 2 , Figure 1 is a schematic diagram of a bearing system provided by an embodiment of the present utility model. Figure 2Exploded view of the carrying system provided by an embodiment of the present utility model. An embodiment of the present utility model provides a carrying system for carrying sheets, including a workbench 100 and a blanking device 200 disposed on the workbench 100; the workbench 100 includes a support table 120 and a carrying plate 110 disposed on the support table 120, and the carrying plate 110 has a blanking hole 130; the blanking device 200 includes a fitting 210 and a blanking assembly 300 both disposed between the support table 120 and the carrying plate 110, the fitting 210 is connected to the support table 120, and the blanking assembly 300 is slidably connected to the fitting 210 in a first direction to adjust the relative position between the blanking assembly 300 and the carrying plate 110 through the fitting 210; the blanking assembly 300 has a blanking column 390, and the blanking column 390 can extend out of the blanking hole 130 to drive the sheet placed on the carrying plate 110 to move relative to the carrying plate 110 in a second direction, where the second direction forms an angle with the first direction.

[0034] Specifically, in this application, the sheet is used to be placed on the carrying plate 110. The blanking columns 390 of the respective blanking assemblies 300 are received in the blanking holes 130 and can extend relative to the blanking holes 130, so as to be able to drive the sheet to lift relative to the carrying plate 110 in the second direction, so that there is a gap between the sheet and the carrying plate 110, facilitating the manipulator to extend into the gap to lift the sheet. Since the blanking assembly 300 is connected to the fitting 210 and can move relative to the fitting 210 in the first direction, the relative position between the blanking assembly 300 and the carrying plate 110 can be adjusted, thereby changing the supporting position of the sheet to avoid uneven stress during the support of the sheet, reducing warping deformation or offset of the sheet, and facilitating subsequent processes.

[0035] Wherein, the first direction is the width or length direction of the carrying plate 110, the second direction is the thickness direction of the carrying plate 110, the second direction is perpendicular to the first direction, and the second direction is parallel to the gravity direction. It should be noted that for the convenience of description, taking the attached drawings of the specification Figure 1 as an example, XX' is defined as the first direction, YY' is defined as the second direction, and ZZ' is defined as the third direction. The third direction is perpendicular to both the first direction and the second direction. The following descriptions are all made in terms of the first direction, the second direction, and the third direction.

[0036] Refer to Figure 1 and Figure 2 , in one of the embodiments, the carrying system further includes a first slider 220. The fitting 210 is provided with a fitting groove 230 extending in the first direction. The first slider 220 is connected to the blanking assembly 300, and the first slider 220 is slidably connected to the fitting groove 230.

[0037] Specifically, the first sliding block 220 is accommodated in the matching groove 230 and is slidably connected to the groove wall of the matching groove 230 along the first direction, thereby playing a guiding role, so that the lifting assembly 300 can move stably along the first direction.

[0038] See also Figure 1 and Figure 2 In one embodiment, the supporting system further includes a fastener 250, which is passed through the top material assembly 300 and connected to the first slider 220. The fastener 250 can move relative to the groove wall of the matching groove 230 to abut against the groove wall of the matching groove 230 to limit the relative movement between the first slider 220 and the groove wall of the matching groove 230.

[0039] Specifically, the ejection assembly 300 is provided with a connection hole 380, the first slider 220 is provided with a fastening hole 370, the fastener 250 is passed through the connection hole 380 and is threadedly connected to the hole wall of the connection hole 380, and the fastener 250 is passed through the fastening hole 370 and is threadedly connected to the hole wall of the fastening hole 370, so that the ejection assembly 300 and the first slider 220 are stably connected. By rotating the fastener 250, the fastener 250 moves relative to the first slider 220 to extend out of the fastening hole 370, so that it can be pressed against the groove wall of the matching groove 230, increasing the friction between the fastener 250 and the groove wall of the matching groove 230, so as to limit the relative movement between the first slider 220 and the groove wall of the matching groove 230, thereby improving the stability of the ejection assembly 300, so that the ejection column 390 can stably support the plate.

[0040] The connection between the ejection assembly 300 and the first slider 220 is realized by the fastener 250, and the relative movement between the first slider 220 and the groove wall of the matching groove 230 is restricted, which reduces the setting of components, simplifies the operation steps, and improves the convenience of the installation of the bearing system. Preferably, the fastener 250 extends along the second direction.

[0041] Furthermore, there is a gap between the first slider 220 and the bottom wall of the matching groove 230, so that when adjusting the position of the first slider 220, the distance between the fastener 250 and the bottom wall of the matching groove 230 can be observed through the gap to avoid excessive rotation of the fastener 250, which causes the top material assembly 300 to separate from the first slider 220, thereby improving the reliability of the bearing system.

[0042] See also Figure 1 , Figure 2 and Figure 3 , Figure 3 A schematic diagram of a transfer part in a bearing system provided in an embodiment of the utility model.

At the same time, the setting that the boss 330 is inserted into the mating groove 230 and abuts against the groove wall of the mating groove 230 can also guide the movement of the first slider 220 in the first direction.

[0044] See also Figure 1 and Figure 2 In one embodiment, the mating piece 210 extends along the first direction, and a protrusion 350 is provided on the side of the lifting assembly 300 away from the supporting plate 110. The protrusion 350 is spaced apart from the boss 330, and the protrusion 350 faces the side of the boss 330 and is loosely matched with the mating piece 210.

[0045] Specifically, the boss 330 abuts against the groove side walls of the mating groove 230 on both sides along the third direction, wherein the third direction is perpendicular to both the first direction and the second direction, the protrusion 350 and the boss 330 are located on the same side of the top material assembly 300, and the protrusion 350 is clearance-matched with the mating piece 210 on the side facing the boss 330, so that the movement of the top material assembly 300 relative to the mating piece 210 in the third direction is restricted by the boss 330 and the protrusion 350, so that the top material assembly 300 stably supports the plate.

[0046] Furthermore, the number of the matching pieces 210 is at least two, and at least two matching pieces 210 are arranged at intervals along the third direction, and each matching piece 210 is provided with a lifting assembly 300 .

[0049] Specifically, the connection hole 380 is provided on the adapter 320, and the driving part 310 is provided below the carrying plate 110 to drive the lifting column 390 to rise and fall, so that the lifting column 390 can extend out of the lifting hole 130 to drive the plate to be lifted relative to the carrying plate 110. Preferably, the driving part 310 is a cylinder, and the lifting column 390 is a piston rod of the cylinder.

[0051] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 4 A schematic diagram of a load-bearing plate in a load-bearing system provided in one embodiment of the utility model.

The at least two matching pieces 210 are arranged in parallel and at intervals, and each lifting component 300 is slidably connected to each matching piece 210 respectively.

[0053] Specifically, each ejection column 390 has a corresponding driving part 310, so that when each ejection assembly 300 moves along the first direction relative to the matching piece 210, it can drive each ejection column 390 to move independently, thereby improving the compatibility with plates of different sizes and improving the adaptability of the bearing system.

[0054] Furthermore, at least two lifting material assemblies 300 are spaced apart along the first direction, and the lifting material assemblies 300 can be moved relative to the matching piece 210 via the first slider 220 to adjust the distance between the lifting material assemblies 300 so that the plate is stably supported.

The second slider is connected to the bearing plate 110 and is slidably connected to the mating groove 230, so as to adapt to bearing plates 110 of different sizes. Wherein, the structure of the second slider is the same as that of the first slider 220, and the fastener 250 is used to limit the bearing plate 110 and the fitting 210 in the first direction.

[0056] Further, the ejector hole 130 extends in the first direction, and the two hole walls of the ejector hole 130 in the third direction are used to abut against the ejector post 390, so as to limit the movement of the ejector post 390 in the third direction, and improve the stability of the ejector post 390 supporting the plate.
