Of course, they are merely examples, and the purpose is not to limit the utility model.

[0048] See also Figures 1 to 4 The embodiment of the utility model provides a separation and combination mechanism 100 for a PCB board 10, wherein the board 10 has a first surface 10a and a second surface 10b along the thickness direction. The separation and combination mechanism 100 is used to stack a plurality of separated boards 10 so that the two first surfaces 10a of the two stacked boards 10 are stacked relative to each other, and to split a plurality of stacked boards 10 so that the first surfaces 10a of all the split boards 10 face the same direction.

[0049] The above-mentioned PCB board 10 separation and combination mechanism 100 can realize stacking of each board 10 with the first surface 10a facing each other, or split the stacked boards 10 and keep the first surface 10a of each board 10 facing upward, thereby realizing automatic stacking or splitting of boards 10 and saving labor costs.

[0050] Specifically, during the processing of the printed circuit board (PCB), the copper clad laminate 20 needs to be cut and drilled first. In the process of drilling the copper clad laminate 20, the sheet 10 is stacked in the order of the pad 18, the copper clad laminate 20 and the aluminum sheet 22, and is pierced with pins and fixed with tape around the edges as a sheet 10. On one side of the aluminum sheet 22, the end face of the pin is basically flush with the surface where the aluminum sheet 22 is located. On one side of the pad 18, the pin extends out to a certain length and serves as a positioning member 11 of the sheet 10 in the subsequent processing process. Since the pin extends out on one side of the pad 18, the sheets 10 are stacked opposite to each other on the side of the aluminum sheet 22 during transportation, and the two sheets 10 are stacked at 90 degrees to avoid the protruding position of the pin, which facilitates the transportation of the sheets 10.

[0051] During processing, it is necessary to distinguish the front and back sides of the sheet material 10. In one sheet material 10, the surface on the side where the aluminum sheet 22 is located can be regarded as the front side, and the surface on the side where the pad 18 is located can be regarded as the back side.

[0052] At present, the process of feeding the sheet 10 to the drilling machine is manually distinguishing the front and back of the sheet 10 and separating the stacked sheets 10 to feed the sheet to the drilling machine. The sheet 10 stacked on the front and back can be flexibly separated by manual operation to prevent the sheet 10 from being damaged and deformed. However, the production process with manual participation has a low level of automation and high labor costs.

[0053] At the same time, since the sheets 10 stacked on the front and back sides are of the same size and overlap, it is difficult for conventional manipulators and other equipment to properly split the stacked sheets 10. At the same time, for sheets 10 of different materials and sizes, during the process of splitting and transporting the sheets 10, problems such as falling off or damaging the sheets 10 may occur.

[0054] Based on the above problems, the embodiment of the utility model provides a PCB board 10 separation and combination mechanism 100. The board 10 has a first surface 10a and a second surface 10b along the thickness direction. When the board 10 is stacked in the order of a backing plate 18, a copper-clad board 20 and an aluminum sheet 22, as shown in FIG. Figure 3 As shown, the surface on the side of the aluminum sheet 22 can be used as the first surface 10a, and the surface on the side of the pad 18 can be used as the second surface 10b. That is, the first surface 10a is the front side of the sheet 10, and the second surface 10b is the back side of the sheet 10. The front and back stacking of the two sheets 10 means that the first surfaces 10a of the two sheets 10 are stacked relative to each other.

[0055] The splitting and combining mechanism 100 is used to split two sheets 10 stacked relative to each other with their first surfaces 10a facing upwards at the same time. In addition, the splitting and combining mechanism 100 can also stack the sheets 10 with their first surfaces 10a facing upwards at the same time, so that the first surfaces 10a of the two sheets 10 are stacked relative to each other.

[0056] When the splitting and combining mechanism 100 is used to split the sheet materials 10, the sheet materials 10 are stacked in pairs, with the first surfaces 10a facing each other, and each pair of sheet materials 10 are stacked at 90 degrees and transported to the splitting and combining mechanism 100 for splitting. The two stacked sheet materials 10 are placed on the working platform of the splitting and combining mechanism 100, and the splitting and combining mechanism 100 can split the stacked sheet materials 10 and keep the first surfaces 10a facing upwards.

[0057] When the separating and combining mechanism 100 is used to stack the sheets 10, the sheets 10 keep the first side 10a facing upwards. After the sheets 10 are placed on the separating and combining mechanism 100 respectively, the separating and combining mechanism 100 stacks the first sides 10a of the two stacks of sheets 10 relative to each other, and the grabbing mechanism 16 transfers the stacked sheets 10 to the stacking mechanism 12. After a certain number of sheets 10 are accumulated in the stacking mechanism 12, they can be transported to other processing equipment.

[0058] In certain embodiments, the splitting and joining mechanism 100 includes a first working platform 26 , a second working platform 28 , and a first driving device 24 .

[0059] The first working platform 26 and the second working platform 28 are used to fix the sheet material 10 with the second surface 10b facing the working platform. The first driving device 24 is used to drive the first working platform 26 and the second working platform 28 to drive the sheet material 10 to switch between the first station and the second station.

[0060] At the first work station, the first working platform 26 and the second working platform 28 are basically parallel along the first direction, and the first surfaces 10a of the two stacked sheets 10 are opposite and fixed on the first working platform 26 or the second working platform 28, or the two sheets 10 are respectively fixed on the first working platform 26 and the second working platform 28.

[0061] At the second workstation, the angle between the first working platform 26 and the second working platform 28 and the second direction ranges from [-15°, 15°], the first surfaces 10a of the sheets 10 on the first working platform 26 and the second working platform 28 are opposite, and the first direction and the second direction are perpendicular to each other.

[0062] In this way, the first working platform 26 and the second working platform 28 are driven to drive the sheet material 10 to switch between the first work station and the second work station to achieve splitting and stacking of the sheet material 10.

[0063] Specifically, when the splitting and combining mechanism 100 is used to stack the sheets 10, the sheets 10 are placed on the first working platform 26 and the second working platform 28 with the first side 10a facing upward, and the splitting and combining mechanism 100 stacks the first sides 10a of the two sheets 10 relative to each other by switching between the first workstation and the second workstation.

[0064] At the first work station, the first working platform 26 and the second working platform 28 are substantially parallel along the first direction, that is, the first working platform 26 and the second working platform 28 are parallel along the first direction, and the above parallel relationship is within the allowable error range.

[0065] At the second workstation, the angle between the first work platform 26 and the second work platform 28 and the second direction ranges from [-15°, 15°]. When the angle between the first work platform 26 and the second work platform 28 and the second direction is 0 degrees, the first work platform 26 and the second work platform 28 are parallel along the second direction. For example, the angle between the first work platform 26 and the second work platform 28 and the second direction can be -15°, -13°, -10°, -5°, 0°, 2°, 5°, 8°, 11°, 12° and 15°, or any other value within the range of [-15°, 15°]. The first work platform 26 and the second work platform 28 can both perform actions at the second workstation. When the angle between the first work platform 26 and the second work platform 28 and the second direction is greater than 15° or less than -15°, the sheet 10 may fall from the work platform or fail to perform actions at the second workstation due to the excessive angle between the first work platform 26 and the second work platform 28.

[0066] At this time, the upper Figure 1 The positive direction of the Z axis is shown in FIG. 1 , and the sheet 10 is placed on the first working platform 26 and the second working platform 28, the first working platform 26 and the second working platform 28 are in the first working position, and the sheet 10 keeps the first surface 10a facing Figure 1 The state in the positive direction of the Z axis is shown in .

[0067] In the description of this article, the first direction is Figure 1 The X-axis direction is shown in Figure 1 The Z-axis direction shown in the figure, the third direction is Figure 1 The Y-axis direction shown in .

[0068] In some embodiments, the first working platform 26 and the second working platform 28 both include a supporting platform 32 and a rotating shaft 31, the separation and combination mechanism 100 includes a base 25, the supporting platform 32 is rotatably connected to the base 25 through the rotating shaft 31, and the first driving device 24 is used to drive the supporting platforms 32 of the first working platform 26 and the second working platform 28 to rotate relative to the base 25 around the rotating shaft 31 so that the first working platform 26 and the second working platform 28 can switch between the first work station and the second work station.

[0069] In this way, the first driving device 24 drives the supporting platform 32 to drive the sheet material 10 to switch between the first station and the second station, thereby realizing the splitting or stacking of the sheet material 10 .

[0070] Specifically, the first working platform 26 and the second working platform 28 are rotatably connected to the base 25 via the rotating shaft 31, and the first driving device 24 can drive the supporting platform 32 to rotate relative to the base 25, thereby realizing the switching of the first working platform 26 and the second working platform 28 between the first workstation and the second workstation.

[0071] The splitting and combining mechanism 100 may include a first driving device 24 that connects the first working platform 26 and the second working platform 28 respectively and drives the first working platform 26 and the second working platform 28 to switch between the first work station and the second work station.

[0072] Alternatively, the splitting and combining mechanism 100 may include two first driving devices 24, which are respectively connected to the first working platform 26 and the second working platform 28, and drive the first working platform 26 and the second working platform 28 to switch between the first workstation and the second workstation.

[0073] See also Figure 4 and Figure 5 In some embodiments, the first working platform 26 and the second working platform 28 both include a fixing device 30 , which is disposed on a carrier platform 32 , and is used to fix the sheet material 10 on the carrier platform 32 .

[0074] In this way, the sheet material 10 can be fixed on the first working platform 26 and the second working platform 28 through the fixing device 30, ensuring that the sheet material 10 placed thereon is fixed when the first working platform 26 and the second working platform 28 are switched between the first workstation and the second workstation. At the same time, the stacked sheets 10 can be split by the fixing device 30.

[0075] Specifically, the first working platform 26 and the second working platform 28 are both provided with a fixing device 30. When the first working platform 26 and the second working platform 28 are switched between the first work station and the second work station, the fixing device 30 can fix the sheet material 10 placed on the first working platform 26 and the second working platform 28. At the same time, the fixing devices 30 on the first working platform 26 and the second working platform 28 cooperate with the switching between different work stations to realize the splitting and stacking of the sheet material 10.

[0076] When the stacked sheets 10 are separated, the stacked sheets 10 are placed on the first working platform 26, and the fixing device 30 thereon fixes the second surface 10b of the lower sheet 10 on the bearing platform 32 of the first working platform 26. The first working platform 26 and the second working platform 28 are switched to the second station, and the second surface 10b of the upper sheet 10 is close to the second working platform 28. At this time, the fixing device 30 of the second working platform 28 fixes the second surface 10b of the upper sheet 10. The first working platform 26 and the second working platform 28 are switched to the first station again, so that the stacked sheets 10 can be separated, and each sheet 10 can keep the first surface 10a facing upward.

[0077] When stacking the sheets 10, the sheets 10 are placed on the first working platform 26 and the second working platform 28 respectively. The first working platform 26 and the second working platform 28 respectively fix the sheets 10 thereon and switch to the second work station. At this time, the first sides 10a of the two sheets 10 are opposite to each other, and the first working platform 26 or the second working platform 28 cancels the fixation of the sheets 10, so that the first sides 10a of the two sheets 10 are stacked relative to each other. Finally, the first working platform 26 and the second working platform 28 switch to the first work station to complete the stacking of each sheet 10.

[0078] In some embodiments, the fixing device 30 includes a fixing part 301, a telescopic part 302 and a second driving device (not shown), the fixing part 301 is fixedly connected to the telescopic part 302, the telescopic part 302 is fixedly connected to the supporting platform 32 of the first working platform 26 and the second working platform 28, respectively, and the second driving device is used to drive the telescopic part 302 to drive the fixing part 301 to move closer to or away from the supporting platform 32.

[0079] In this way, the second driving device can drive the telescopic portion 302 to drive the fixing portion 301 to telescope and move, so that the fixing portion 301 can contact and fix the plate material 10 .

[0080] Specifically, the telescopic part 302 and the second driving device can enable the fixing part 301 on the fixing device 30 to telescope. When the fixing part 301 contracts, interference with the movement of the sheet material 10 on the supporting platform 32 is avoided. When the fixing part 301 extends, it can be used to fix the sheet material 10 on the supporting platform 32.

[0081] The second driving device drives the telescopic part 302 to drive the fixed part 301 to extend and retract, wherein the extension direction is Figure 1 The positive direction of the Z axis is shown, and the contraction direction is Figure 1 The negative Z direction is shown.

[0082] In an example, Fig.11 and Fig.12As shown, when the splitting and combining mechanism 100 splits the sheet material 10, first, the first working platform 26 and the second working platform 28 are under the first working position, and the two stacked sheets 10 are placed on the first working platform 26 and moved to the working position. During the movement of the sheet material 10, the second driving device drives the telescopic rod to drive the fixing part 301 to contract, so as to avoid the fixing part 301 from interfering with the movement of the sheet material 10. After the sheet material 10 moves to the working position, the fixing device 30 on the first working platform 26 fixes the second surface 10b of the sheet material 10 in contact with the carrier 32. Then the first working platform 26 and the second working platform 28 switch to the second working position. At this time, the first surfaces 10a of the two stacked sheets 10 are opposite, the second surface 10b of one sheet material 10 is fixed by the fixing device 30 on the first working platform 26, and the second surface 10b of the other sheet material 10 faces the second working platform 28. The fixing part 301 on the second working platform 28 needs to contact and fix the second surface 10b of the sheet material 10 facing the second working platform 28. There is a certain distance between the first working platform 26 and the second working platform 28. At this time, the telescopic part 302 can be driven by the second driving device to drive the fixing part 301 to move toward the position of the sheet 10 until the fixing part 301 on the second working platform 28 contacts the second surface 10b of the sheet 10 and fixes it.

[0083] The working position is a position where the sheet 10 can be fixed after the first working platform 26 and the second working platform 28 limit the sheet 10. In this position, when the sheet 10 switches positions with the first working platform 26 and the second working platform 28, it can be ensured that there is basically no relative movement between the sheet 10 and the carrier 32 and the stacked sheets 10.

[0084] In some embodiments, the first working platform 26 and the second working platform 28 both include a blocking member 34, which is disposed on the supporting platform 32. The blocking member 34 includes a connecting portion 341 and a blocking portion 342. The connecting portion 341 is connected to the blocking portion 342, the connecting portion 341 is fixedly connected to the supporting platform 32, and the blocking portion 342 extends toward a side away from the supporting platform 32.

[0085] In this way, the sheet material 10 can be limited in the working position by the blocking member 34 .

[0086] Specifically, Figures 7 to 9As shown, the blocking member 34 is arranged on the carrier platform 32, and the connecting portion 341 is fixedly connected to the carrier platform 32. After the sheet 10 is placed on the carrier platform 32, the sheet 10 needs to be moved to abut against the blocking portion 342. At this time, in the first working position, the blocking portion 342 can limit the position of the sheet 10 on the carrier platform 32 in the first direction. In the second working position, the blocking portion 342 supports one side of the sheet 10 and can limit the position of the sheet 10 in the second direction. The position where the sheet 10 abuts against the blocking portion 342 on the carrier platform 32 is used as the working position of the sheet 10. In this position, it can be ensured that when the sheet 10 switches the working position with the first working platform 26 and the second working platform 28, there is basically no relative movement between the sheet 10 and the carrier platform 32 and the stacked sheets 10.

[0087] The first working platform 26 and the second working platform 28 are installed on the base 25. The first driving mechanism is respectively arranged on the first working platform 26 and the second working platform 28, and drives the first working platform 26 and the second working platform 28 to rotate around the first driving device 24 to switch from the first station to the second station. The sheet 10 is placed on the first working platform 26 and the second working platform 28. At the second station, the blocking member 34 can support one edge of the sheet 10 and cooperate with the fixing device 30 to fix the position of the sheet 10 on the carrier 32, and at the same time, it can prevent the tape fixing the sheet 10 from falling off.

[0088] See also Fig.11 and Fig.13 In some embodiments, the separation and combination mechanism 100 includes a moving device, and the second working platform 28 is movably mounted on the base 25 through the moving device.

[0089] In this way, the first working platform 26 and the second working platform 2828 can be prevented from interfering with each other when switching workstations.

[0090] Specifically, the moving device 40 can control the second work platform 28 to move on the base 25, so as to adjust the distance between the second platform and the first platform in the first direction. When the first work platform 26 and the second work platform 28 are switched between the first work station and the second work station, in order to prevent the first work platform 26 and the second work platform 28 from interfering with each other, the moving device 40 can drive the second work platform 28 to move a certain distance in the direction away from the first work platform 26. When the first work platform 26 and the second work platform 28 need to approach each other at the second work station, the moving device 40 can drive the second work platform 28 to move in the direction close to the first work platform 26.

[0091] The moving device 40 may be an electric push rod, a hydraulic cylinder, or other devices that can drive the second working platform 28 to move in the first direction.

[0092] In one embodiment, the moving device 40 may be disposed on the first working platform 26 to adjust the relative position between the first working platform 26 and the second working platform 28 .

[0093] In one embodiment, the moving device 40 may be disposed on the first working platform 26 and the second working platform 28 , respectively, for adjusting the relative position between the first working platform 26 and the second working platform 28 .

[0094] See also Figure 4 and Figure 5 In some embodiments, the first working platform 26 and the second working platform 28 both include a conveying device 36, which is disposed on the supporting platform 32. The conveying device includes a conveying component 361 and a third driving device (not shown). The third driving device is used to drive the conveying component to drive the sheet material 10 to abut against the blocking portion.

[0095] In this way, the sheet materials 10 placed on the first working platform 26 and the second working platform 28 can be moved to positions convenient for splitting and stacking operations, ensuring that subsequent splitting or stacking operations proceed smoothly.

[0096] Specifically, the sheet 10 is placed on the supporting platform 32 of the first working platform 26 and the second working platform 28, and the sheet 10 is moved by the conveying device 36. After one edge of the sheet 10 contacts the blocking member 34, the conveying device 36 stops working, and the sheet 10 is at the working position.

[0097] The first working platform 26 and the second working platform 28 are switched to the second working position, and the blocking member 34 can cooperate with the fixing device 30 to fix the sheet material 10 on the carrying platform 32 .

[0098] In one embodiment, the conveying component may be a conveyor belt disposed on the carrying platform 32 , and the conveyor belt may drive the sheet material 10 on the carrying platform 32 to move until the sheet material 10 abuts against the blocking portion.

[0099] In some embodiments, the conveying device 36 includes a lifting drive assembly, and the lifting drive assembly is used to drive the conveying assembly to move along the second direction relative to the supporting platform 32.

[0100] In this way, the conveying device 36 can adjust the height of the plate material 10 relative to the supporting platform in the second direction when conveying the plate material 10 .

[0101] Specifically, when the sheet material 10 is placed on the carrier 32, the conveyor 36 can be used to drive the sheet material 10 to move in the first direction. After the stacked sheet materials 10 are separated, the sheet materials 10 can be directly transported to the processing equipment of the next process through the conveyor 36. Through the lifting drive assembly, the position of the sheet material 10 can be adjusted in the second direction, so that the sheet materials 10 on the first working platform 26 and the second working platform 28 are aligned in the second direction, so that the sheet material 10 can be conveyed to other processing equipment through the conveyor 36 through the first working platform 26 and the second working platform 28.

[0102] At the same time, through the lifting drive device, when the fixing device 30 fixes the sheet material 10, the conveying device can be retracted close to the supporting platform 32 to avoid interference with the contact between the fixing device 30 and the sheet material 10.

[0103] In some embodiments, the sheet 10 includes a positioning member 11, and a limiting groove 33 is provided on the supporting platform 32. When the sheet 10 is placed on the supporting platform 32, the positioning member 11 can be movably inserted in the limiting groove 33, and the limiting groove 33 is used to guide the positioning member 11 to drive the sheet 10 to move on the supporting platform 32.

[0104] In this way, the limiting groove 33 can cooperate with the positioning piece 11 of the plate 10 to limit the plate 10 when the plate 10 moves along with the carrying platform 32 .

[0105] Specifically, Figure 4 As shown, when the sheet 10 is placed on the carrier 32, the setting direction of the positioning member 11 on the sheet 10 is consistent with the length direction of the limiting groove 33, and the width of the limiting groove 33 is much larger than the diameter of the positioning member 11. Therefore, when the sheet 10 is placed on the carrier 32, the positioning member 11 can be inserted into the limiting groove 33, and when the transmission device 36 drives the sheet 10 to move, the positioning member 11 moves in the limiting groove 33 along its length direction, and the limiting groove 33 can limit the movement of the sheet 10 in the width direction of the limiting groove 33.

[0106] In some embodiments, the first working platform 26 and the second working platform 28 both include a clapper device, which is disposed on the support platform 32 and is used to drive the sheet material 10 to move to a grabbing position of the support platform 32 .

[0107] The clapping device includes a fourth driving device (not shown), a first positioning plate 38 and a second positioning plate 39. The first positioning plate 38 and the second positioning plate 39 define a placement area for the sheet material 10. At the first workstation, the fourth driving device is used to drive the first positioning plates 38 to move closer to or farther away from each other along the third direction, and to drive the second positioning plates 39 to move closer to or farther away from each other along the first direction.

[0108] In this way, the sheet material 10 on the carrier platform 32 can be positioned so that the subsequent grasping mechanism 16 can grasp the sheet material 10 accurately.

[0109] Specifically, Figure 6 and Figure 7 As shown, the first positioning plate 38 and the second positioning plate 39 are respectively arranged on the supporting platform 32 along the third direction and the second direction, and are used to center and position the sheets 10 of different sizes. After the separation and combination mechanism 100 completes the splitting of the sheets 10, the plate-clapping device is used to position the sheets 10 to facilitate transportation when the sheets 10 are transferred to the next process.

[0110] The first positioning plate 38 and the second positioning plate 39 are mounted on the support platform 32 in two directions perpendicular to each other. Figure 4 and Figure 5 As shown, at the first station, the paving device includes a first positioning plate 38 arranged opposite to each other in the third direction and a second positioning plate 39 arranged opposite to each other in the first direction. The fourth driving device can drive the first positioning plates 38 opposite to each other in the third direction to move toward each other, and drive the second positioning plates 39 opposite to each other in the first direction to move toward each other, so that the sheet 10 placed in the positioning area moves to a preset position on the carrier 32. At the preset position, the subsequent manipulator or other transportation device used to move and transport the sheet 10 can accurately position the sheet 10, so that the sheet 10 on the carrier 32 can be accurately and quickly transferred.

[0111] To summarize, the sheet 10 is placed on the first working platform 26 or the second working platform 28. The first working platform 26 and the second working platform 28 drive the sheet 10 to switch between the first work station and the second work station, so that each sheet 10 is stacked with the first side 10a facing each other, or the stacked sheets 10 are split and the first side 10a of each sheet 10 is kept facing upward, thereby realizing automatic stacking or splitting of the sheets 10 and saving labor costs.

[0112] When the stacked sheet materials 10 are separated, Figure 1 As shown, the first working platform 26 and the second working platform 28 are currently at the first work station, the sheets 10 are stacked in pairs, and the first surfaces 10a are placed on the first working platform 26. After the conveyor 36 moves the stacked sheets 10 to the working position, the first working platform 26 fixes the sheets 10 and switches to the second work station. Fig.10 The moving device 40 controls the second working platform 28 to approach the sheet material 10, and the fixing device 30 on the second working platform 28 fixes the second surface 10b of the sheet material 10, as shown in FIG. Fig.12Then the mobile device controls the second work platform 28 to move away from the first work platform, thereby driving the two stacked sheets to separate. At this time, the first work platform 26 and the second work platform 28 switch to the first station, completing the separation of the stacked sheets 10, as shown. Fig.14 shown.

[0113] A conveyor line 200 for PCB board materials 10 according to an embodiment of the utility model comprises a stacking mechanism 12 , a separation and combination mechanism 100 as described in any of the above embodiments, and a grasping mechanism 16 .

[0114] The stacking mechanism is used to place the sheet materials, and the grabbing mechanism is used to transfer the sheet materials between the stacking mechanism and the separating and combining mechanism.

[0115] The above-mentioned conveyor line 200 and the separating and combining mechanism 100 are used to stack or split the sheets 10 with the front and back sides. The sheets 10 are transferred between the stacking mechanism 12 and the separating and combining mechanism 100 through the grasping mechanism 16, so as to realize the automatic stacking or splitting of the sheets 10, which is beneficial to improve the automation level of the sheet material 10 processing flow and reduce labor costs.

[0116] Specifically, Fig.15 As shown, when the splitting and combining mechanism 100 is used to split the sheet materials 10, the sheet materials 10 are stacked in pairs, the first surfaces 10a are opposite, and each two stacks of sheet materials 10 are stacked at 90 degrees and transported to the stacking mechanism. The grabbing mechanism 16 grabs the two stacks of sheet materials 10 stacked front and back and places them on the splitting and combining mechanism 100, and the splitting and combining mechanism 100 splits the stacked sheet materials 10 and keeps the first surfaces 10a facing upwards.

[0117] When the separating and combining mechanism 100 is used to stack the sheets 10, the sheets 10 keep the first side 10a facing upwards, and the grabbing mechanism 16 places the sheets 10 on the separating and combining mechanism 100 respectively. The separating and combining mechanism 100 stacks the first sides 10a of the two stacks of sheets 10 relative to each other, and the grabbing mechanism 16 transfers the stacked sheets 10 to the stacking mechanism 12. After a certain number of sheets 10 are accumulated in the stacking mechanism 12, they can be transported to other processing equipment.

[0118] The grabbing mechanism 16 is used to transfer the sheet material 10 between the stacking mechanism 12 and the separating and combining mechanism 100 , can be used to grab the sheet material 10 according to the size data of the sheet material 10 , and can rotate and stack the sheet material 10 .
