Of course, they are merely examples and are not intended to limit the present invention.

[0064] Please refer to Figures 1 to 4 , an embodiment of the present invention provides a separating and combining mechanism 100 for a PCB sheet 10. The sheet 10 has a first surface 10a and a second surface 10b in the thickness direction. The separating and combining mechanism 100 is used to stack a plurality of separated sheets 10 so that the two first surfaces 10a of the two stacked sheets 10 face each other, and to split the plurality of stacked sheets 10 so that the first surfaces 10a of all the split sheets 10 face the same direction.

[0065] The above-mentioned separating and combining mechanism 100 for the PCB sheet 10 can stack each sheet 10 in a state where the first surfaces 10a face each other, or split the stacked sheets 10 and keep the first surfaces 10a of each sheet 10 facing upward, realizing the automatic stacking or splitting of the sheets 10 and saving labor costs.

[0066] Specifically, in the processing of a printed circuit board (PCB), it is first necessary to cut and drill the copper-clad laminate 20. In the process of drilling the copper-clad laminate 20, the sheet material 10 is stacked in the order of the backing plate 18, the copper-clad laminate 20, and the aluminum sheet 22 and pierced with pins, and fixed with tape around, serving as a sheet material 10. On one side of the aluminum sheet 22, the end face of the pin is substantially flush with the surface where the aluminum sheet 22 is located. On one side of the backing plate 18, the pin extends a certain length and serves as a positioning member 11 of the sheet material 10 in the subsequent processing. Since the pin extends on one side of the backing plate 18, when transporting the sheet material 10, stack the sheet materials 10 with the aluminum sheet 22 sides facing each other in pairs, and the two sheet materials 10 are stacked at a 90-degree angle to avoid the protruding position of the pin, so as to facilitate the transportation of the sheet material 10.

[0067] 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 used as the front side, and the surface on the side where the backing plate 18 is located can be used as the back side.

[0068] In the process of loading the drilling machine, currently, the front and back sides of the sheet material 10 are manually discriminated and the stacked sheet materials 10 are separated and loaded onto the drilling machine. Manually operate to flexibly separate the front and back stacked sheet materials 10 to prevent the sheet material 10 from being damaged and deformed. However, in the production process with manual participation, the automation level is low and the labor cost is high.

[0069] At the same time, since the sizes of the front and back stacked sheet materials 10 are the same and they overlap and stack, it is difficult for conventional equipment such as manipulators to better split the stacked sheet materials 10. At the same time, for sheet materials 10 of different materials and sizes, problems such as dropping the sheet or damaging the sheet material 10 may occur during the process of splitting and transporting the sheet material 10.

[0070] Based on the above problems, an embodiment of the present invention provides a separating and combining mechanism 100 for a PCB sheet material 10. Among them, the sheet material 10 has a first surface 10a and a second surface 10b in the thickness direction. When the sheet material 10 is stacked in the order of the backing plate 18, the copper-clad laminate 20, and the aluminum sheet 22, as Figure 3 shown, the surface on the aluminum sheet 22 side can be used as the first surface 10a, and the surface on the backing plate 18 side can be used as the second surface 10b. That is, the first surface 10a is the front side of the sheet material 10, and the second surface 10b is the back side of the sheet material 10. The two sheet materials 10 are stacked with the front sides facing each other, that is, the first surfaces 10a of the two sheet materials 10 are stacked facing each other.

[0071] The separating and combining mechanism 100 is used to split two sheet materials 10 stacked with the first surfaces 10a facing each other and keep the first surfaces 10a facing upward at the same time. And the separating and combining mechanism 100 can also stack the sheet materials 10 with the first surfaces 10a facing upward at the same time, so that the first surfaces 10a of the two sheet materials 10 are stacked facing each other.

[0072] 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 every two sheet materials 10 are stacked and transported to the splitting and combining mechanism 100 at a 90-degree angle for splitting. The two sheet materials 10 stacked with opposite orientations 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 upward simultaneously.

[0073] When the splitting and combining mechanism 100 is used to stack the sheet materials 10, the sheet materials 10 keep the first surfaces 10a facing upward. After the sheet materials 10 are respectively placed on the splitting and combining mechanism 100, the splitting and combining mechanism 100 stacks the two stacks of sheet materials 10 with the first surfaces 10a facing each other. The grasping mechanism 16 transports the stacked sheet materials 10 to the stacking mechanism 12. When a certain number of sheet materials 10 are accumulated in the stacking mechanism 12, they can be transported to other processing equipment.

[0074] In some embodiments, the splitting and combining mechanism 100 includes a first working platform 26, a second working platform 28, and a first driving device 24.

[0075] The first working platform 26 and the second working platform 28 are used to fix the sheet materials 10 in such a way that the second surfaces 10b face 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 materials 10 to switch between the first working position and the second working position.

[0076] In the first working position, the first working platform 26 and the second working platform 28 are substantially parallel in the first direction. The first surfaces 10a of the two stacked sheet materials 10 face each other and are fixed on the first working platform 26 or the second working platform 28, or the two sheet materials 10 are respectively fixed on the first working platform 26 and the second working platform 28.

[0077] In the second working position, the included 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 sheet materials 10 on the first working platform 26 and the second working platform 28 face each other, and the first direction and the second direction are perpendicular to each other.

[0078] In this way, by driving the first working platform 26 and the second working platform 28 to drive the sheet materials 10 to switch between the first working position and the second working position, the splitting and stacking of the sheet materials 10 are realized.

[0079] Specifically, when the splitting and combining mechanism 100 is used to stack the sheet materials 10, the sheet materials 10 are placed on the first working platform 26 and the second working platform 28 with the first surfaces 10a facing upward. The splitting and combining mechanism 100 stacks the two sheet materials 10 with the first surfaces 10a facing each other by switching between the first working position and the second working position.

[0080] Under the first working station, the first working platform 26 and the second working platform 28 are substantially parallel in the first direction, that is, the first working platform 26 and the second working platform 28 are parallel in the first direction, and the above parallel relationship is within the allowable error range.

[0081] Under the second working station, the range of the included angle between the first working platform 26 and the second working platform 28 and the second direction is [-15°, 15°]. When the included angle between the first working platform 26 and the second working platform 28 and the second direction is 0 degree, the first working platform 26 and the second working platform 28 are parallel in the second direction. For example, the included angle between the first working platform 26 and the second working 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 [-15°, 15°]. The first working platform 26 and the second working platform 28 can both achieve the actions under the second working station. When the included angle between the first working platform 26 and the second working platform 28 and the second direction is greater than 15° or less than -15°, the sheet material 10 may fall off the working platform due to the too large included angle between the first working platform 26 and the second working platform 28, or the actions under the second working station cannot be achieved.

[0082] The upper side at this time is Figure 1 the positive direction of the Z-axis shown in, and it is in the state where the sheet material 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 under the first working station, and the first surface 10a of the sheet material 10 faces Figure 1 the positive direction of the Z-axis shown in.

[0083] In the description of this article, the first direction is Figure 1 the X-axis direction shown in, the second direction is Figure 1 the Z-axis direction shown in, and the third direction is Figure 1 the Y-axis direction shown in.

[0084] In some embodiments, both the first working platform 26 and the second working platform 28 include a bearing platform 32 and a rotating shaft 31. The splitting and combining mechanism 100 includes a base 25. The bearing platform 32 is rotatably connected to the base 25 through the rotating shaft 31. The first driving device 24 is used to drive the bearing 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 be switched between the first working station and the second working station.

[0085] In this way, the first driving device 24 drives the bearing platform 32 to drive the sheet material 10 to be switched between the first working station and the second working station, so as to realize the splitting or stacking of the sheet material 10.

[0086] Specifically, the first working platform 26 and the second working platform 28 are rotatably connected to the base 25 through a rotating shaft 31, and the first driving device 24 can drive the carrier table 32 to rotate relative to the base 25, so as to realize the switching of the first working platform 26 and the second working platform 28 between the first working station and the second working station.

[0087] The separating and combining mechanism 100 may include a first driving device 24 respectively connected to the first working platform 26 and the second working platform 28 and driving the first working platform 26 and the second working platform 28 to switch between the first working station and the second working station.

[0088] Alternatively, the separating and combining mechanism 100 may include two first driving devices 24, and the two first driving devices 24 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 working station and the second working station.

[0089] Please refer to Figure 4 and Figure 5 , in some embodiments, both the first working platform 26 and the second working platform 28 include a fixing device 30, and the fixing device 30 is arranged on the carrier table 32 and is used to fix the sheet material 10 on the carrier table 32.

[0090] 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 on it is fixed when the first working platform 26 and the second working platform 28 are switched before the first working station and the second working station. At the same time, the splitting of the stacked sheet materials 10 is realized through the fixing device 30.

[0091] Specifically, both the first working platform 26 and the second working platform 28 are provided with a fixing device 30. When the first working platform 26 and the second working platform 28 are switched between the first working station and the second working 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, through the cooperation of the fixing devices 30 on the first working platform 26 and the second working platform 28 with the switching between different working stations, the splitting and stacking of the sheet material 10 are realized.

[0092] When splitting the stacked sheet materials 10, the stacked sheet materials 10 are placed on the first working platform 26, and the fixing device 30 thereon fixes the second surface 10b of the lower sheet material 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 working position, and the second surface 10b of the upper sheet material 10 approaches 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 material 10. Then the first working platform 26 and the second working platform 28 are switched to the first working position, so as to realize the separation of the stacked sheet materials 10 and keep the first surface 10a of each sheet material 10 facing upward.

[0093] When stacking the sheet materials 10, the sheet materials 10 are respectively placed on the first working platform 26 and the second working platform 28. The first working platform 26 and the second working platform 28 respectively fix the sheet materials 10 thereon and are switched to the second working position. At this time, the first surfaces 10a of the two sheet materials 10 face each other. The first working platform 26 or the second working platform 28 cancels the fixation of the sheet material 10, so that the first surfaces 10a of the two sheet materials 10 are stacked facing each other. Finally, the first working platform 26 and the second working platform 28 are switched to the first working position to complete the stacking of each sheet material 10.

[0094] In some embodiments, the fixing device 30 includes a fixing part 301, a telescopic part 302 and a second driving device (not shown in the figure). The fixing part 301 is fixedly connected to the telescopic part 302. The telescopic part 302 is respectively fixedly connected to the bearing platforms 32 of the first working platform 26 and the second working platform 28. The second driving device is used to drive the telescopic part 302 to drive the fixing part 301 to approach or move away from the bearing platform 32.

[0095] In this way, the second driving device can drive the telescopic part 302 to drive the fixing part 301 to telescopically move, so that the fixing part 301 can contact and fix the sheet material 10.

[0096] Specifically, the telescopic part 302 and the second driving device can enable the fixing part 301 on the fixing device 30 to telescopically move. When the fixing part 301 contracts, it avoids interfering with the movement of the sheet material 10 on the bearing platform 32. When the fixing part 301 extends, it can be used to fix the sheet material 10 on the bearing platform 32.

[0097] The second driving device drives the telescopic part 302 to drive the fixing part 301 to telescopically move, wherein the extending direction is Figure 1 the positive direction of the Z-axis shown, and the contracting direction is Figure 1 the negative direction of the Z-axis shown.

[0098] In one example, such as Figure 11 and Figure 12As shown in the figure, 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 at the first working station. Two stacked sheet materials 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 interfering with the movement of the sheet material 10. After the sheet material 10 is moved 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 bearing platform 32. Then, the first working platform 26 and the second working platform 28 are switched to the second working station. At this time, the first surfaces 10a of the two sheet materials 10 to be stacked face each other. 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 second driving device can drive the telescopic part 302 to drive the fixing part 301 to move towards the position of the sheet material 10 until the fixing part 301 on the second working platform 28 contacts the second surface 10b of the sheet material 10 and fixes it.

[0099] Among them, the working position is the position where the first working platform 26 and the second working platform 28 can fix the sheet material 10 after limiting the sheet material 10. At this position, when the sheet material 10 follows the first working platform 26 and the second working platform 28 to switch working stations, it can be ensured that there is basically no relative movement between the sheet material 10 and the bearing platform 32 and the stacked sheet materials 10.

[0100] In some embodiments, both the first working platform 26 and the second working platform 28 include a blocking member 34. The blocking member 34 is arranged on the bearing platform 32. The blocking member 34 includes a connecting portion 341 and a blocking portion 342. The connecting portion 341 connects the blocking portion 342. The connecting portion 341 is fixedly connected to the bearing platform 32, and the blocking portion 342 extends towards the side away from the bearing platform 32.

[0101] In this way, the sheet material 10 can be limited to the working position by the blocking member 34.

[0102] Specifically, as Figures 7 to 9As shown, the blocking member 34 is disposed on the carrier 32. The connecting portion 341 is fixedly connected to the carrier 32. After the sheet material 10 is placed on the carrier 32, it is first necessary to move the sheet material 10 to abut against the blocking portion 342. At this time, in the first working position, the blocking portion 342 can define the position of the sheet material 10 on the carrier 32 in the first direction. In the second working position, the blocking portion 342 supports one side of the sheet material 10 and can define the position of the sheet material 10 in the second direction. The position where the sheet material 10 abuts against the blocking portion 342 on the carrier 32 is taken as the working position of the sheet material 10. In this position, it can be ensured that when the sheet material 10 is switched between the first working platform 26 and the second working platform 28, there is basically no relative movement between the sheet material 10, the carrier 32, and the stacked sheet materials 10.

[0103] The first working platform 26 and the second working platform 28 are installed on the base 25. The first driving mechanisms are respectively disposed on 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 rotate around the first driving device 24 to switch from the first working position to the second working position. The sheet material 10 is placed on the first working platform 26 and the second working platform 28. In the second working position, the blocking member 34 can support one side of the sheet material 10 and cooperate with the fixing device 30 to jointly fix the position of the sheet material 10 on the carrier 32, and at the same time, it can prevent the tape for fixing the sheet material 10 from falling off.

[0104] Please refer to Figure 11 and Figure 13 , in some embodiments, the separating and combining mechanism 100 includes a moving device, and the second working platform 28 is movably installed on the base 25 through the moving device.

[0105] In this way, it is possible to prevent interference between the first working platform 26 and the second working platform 28 when switching working positions.

[0106] Specifically, the moving device 40 can control the movement of the second working platform 28 on the base 25, thereby adjusting the distance between the second platform and the first platform in the first direction. When the first working platform 26 and the second working platform 28 are switched between the first working position and the second working position, in order to prevent interference between the first working platform 26 and the second working platform 28, the moving device 40 can drive the second working platform 28 to move a certain distance in a direction away from the first working platform 26. When the first working platform 26 and the second working platform 28 need to be close to each other in the second working position, the moving device 40 can drive the second working platform 28 to move in a direction close to the first working platform 26.

[0107] The moving device 40 can 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.

[0108] In one embodiment, the mobile device 40 may be disposed on the first working platform 26 for adjusting the relative position between the first working platform 26 and the second working platform 28.

[0109] In one embodiment, the mobile device 40 may be respectively disposed on the first working platform 26 and the second working platform 28 for adjusting the relative position between the first working platform 26 and the second working platform 28.

[0110] Please refer to Figure 4 and Figure 5 , in some embodiments, both the first working platform 26 and the second working platform 28 include a conveying device 36. The conveying device 36 is disposed on the carrier table 32. The conveying device includes a conveying component 361 and a third driving device (not shown in the figure). The third driving device is used to drive the conveying component to drive the sheet material 10 to abut against the blocking portion.

[0111] In this way, the sheet material 10 placed on the first working platform 26 and the second working platform 28 can be moved to a position convenient for splitting and stacking operations, ensuring the smooth progress of subsequent splitting or stacking operations.

[0112] Specifically, the sheet material 10 is placed on the carrier tables 32 of the first working platform 26 and the second working platform 28. The conveying device 36 drives the sheet material 10 to move. After one side of the sheet material 10 contacts the blocking member 34, the conveying device 36 stops working. At this time, the sheet material 10 is located at the working position.

[0113] The first working platform 26 and the second working platform 28 are switched to the second working station. The blocking member 34 can cooperate with the fixing device 30 to fix the sheet material 10 on the carrier table 32.

[0114] In one embodiment, the conveying component may be a conveyor belt disposed on the carrier table 32. The conveyor belt can drive the sheet material 10 on the carrier table 32 to move until the sheet material 10 abuts against the blocking portion.

[0115] In some embodiments, the conveying device 36 includes a lifting drive assembly for driving the conveying component to move relative to the carrier table 32 in a second direction.

[0116] In this way, the conveying device 36 can adjust the height of the sheet material 10 relative to the carrier table in the second direction when conveying the sheet material 10.

[0117] Specifically, when the sheet material 10 is placed on the carrier table 32, the conveying device 36 can be used to drive the sheet material 10 to move in the first direction. After the stacked sheet materials 10 are split, the sheet material 10 can be directly transported to the processing equipment of the next process through the conveying device 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 flush in the second direction, so that the sheet material 10 can pass through the first working platform 26 and the second working platform 28 through the conveying device 36 and be transported to other processing equipment.

[0118] At the same time, through the lifting drive device, when the fixing device 30 fixes the sheet material 10, the conveying device can be contracted and close to the carrier table 32 to avoid interference with the contact between the fixing device 30 and the sheet material 10.

[0119] In some embodiments, the sheet material 10 includes a positioning member 11, and the carrier table 32 is provided with a limiting groove 33. When the sheet material 10 is placed on the carrier table 32, the positioning member 11 is movably inserted into the limiting groove 33, and the limiting groove 33 is used to guide the positioning member 11 to drive the sheet material 10 to move on the carrier table 32.

[0120] In this way, the limiting groove 33 can cooperate with the positioning member 11 of the sheet material 10 to limit the sheet material 10 when the sheet material 10 moves along with the carrier table 32.

[0121] Specifically, as Figure 4 shown, when the sheet material 10 is placed on the carrier table 32, the setting direction of the positioning member 11 on the sheet material 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 material 10 is placed on the carrier table 32, the positioning member 11 can be inserted into the limiting groove 33. When the transmission device 36 drives the sheet material 10 to move, the positioning member 11 moves along its length direction in the limiting groove 33, and at the same time, the limiting groove 33 can limit the movement of the sheet material 10 in the width direction of the limiting groove 33.

[0122] In some embodiments, both the first working platform 26 and the second working platform 28 include a slapping device, and the slapping device is arranged on the carrier table 32. The slapping device is used to drive the sheet material 10 to move to the grasping position of the carrier table 32.

[0123] The slapping device includes a fourth driving device (not shown in the figure), a first positioning plate 38 and a second positioning plate 39. A placement area for the sheet material 10 is defined between the first positioning plate 38 and the second positioning plate 39. In the first working position, the fourth driving device is used to drive the first positioning plate 38 to approach or move away from each other in the third direction, and drive the second positioning plate 39 to approach or move away from each other in the first direction.

[0124] In this way, the sheet material 10 on the carrier table 32 can be positioned to facilitate the subsequent gripping mechanism 16 to accurately grip the sheet material 10.

[0125] Specifically, as Figure 6 and Figure 7 shown, the first positioning plate 38 and the second positioning plate 39 are respectively arranged on the carrier table 32 along the third direction and the second direction, and are used for centering and positioning sheet materials 10 of different sizes. After the splitting mechanism 100 completes the splitting of the sheet material 10, the clapper device is used to position the sheet material 10 to facilitate the transportation of the sheet material 10 when it is transferred to the next process.

[0126] The first positioning plate 38 and the second positioning plate 39 are installed on the carrier table 32 in two mutually perpendicular directions. As Figure 4 and Figure 5 shown, in the first working position, the clapper device includes a first positioning plate 38 arranged oppositely along the third direction and a second positioning plate 39 arranged oppositely along the first direction. The fourth driving device can drive the first positioning plates 38 opposite to each other in the third direction and the second positioning plates 39 opposite to each other in the first direction, so that the sheet material 10 placed in the positioning area moves to a preset position on the carrier table 32. In the preset position, the subsequent manipulator or other transportation device used to move and transport the sheet material 10 can accurately position the sheet material 10, so that the sheet material 10 on the carrier table 32 can be accurately and quickly transferred.

[0127] In summary, the sheet material 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 material 10 to switch between the first working position and the second working position, and finally stack each sheet material 10 in a state where the first surface 10a faces each other, or split the stacked sheet materials 10 and keep the first surface 10a of each sheet material 10 facing upward, realizing the automatic stacking or splitting of the sheet material 10 and saving labor costs.

[0128] When splitting the stacked sheet materials 10, as Figure 1 shown, when the current first working platform 26 and the second working platform 28 are in the first working position, the sheet materials 10 are stacked in pairs with the first surface 10a facing each other and placed on the first working platform 26. After the conveying device 36 moves the stacked sheet materials 10 to the working position, the first working platform 26 fixes the sheet material 10 and switches to the second working position. As Figure 10 shown. 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 Figure 12As shown. Then, the mobile device controls the second working platform 28 to move away from the first working platform, thereby driving the separation of the two stacked sheets. At this time, the first working platform 26 and the second working platform 28 are switched to the first working position, and the splitting of the stacked sheets 10 is completed, as Figure 14 shown.

[0129] A conveying line 200 for a PCB sheet 10 according to an embodiment of the present invention includes a stacking mechanism 12, a splitting and combining mechanism 100 described in any of the above embodiments, and a grasping mechanism 16.

[0130] The stacking mechanism is used to place the sheets, and the grasping mechanism is used to transfer the sheets between the stacking mechanism and the splitting and combining mechanism.

[0131] For the above-mentioned conveying line 200, the splitting and combining mechanism 100 is used to stack or split the sheets 10 with front and back sides. The grasping mechanism 16 transfers the sheets 10 between the stacking mechanism 12 and the splitting and combining mechanism 100, realizing the automatic stacking or splitting of the sheets 10, which is beneficial to improving the automation level of the sheet 10 processing process and reducing labor costs.

[0132] Specifically, as Figure 15 shown, when the splitting and combining mechanism 100 is used to split the sheets 10, the sheets 10 are stacked in pairs with the first side 10a facing each other, and each two stacks of sheets 10 are stacked and transported to the stacking mechanism at a 90-degree angle. The grasping mechanism 16 grabs and places the two stacks of sheets 10 stacked with front and back sides on the splitting and combining mechanism 100. The splitting and combining mechanism 100 splits the stacked sheets 10 and keeps the first side 10a facing upward simultaneously.

[0133] When the splitting and combining mechanism 100 is used to stack the sheets 10, the sheets 10 keep the first side 10a facing upward. The grasping mechanism 16 places the sheets 10 on the splitting and combining mechanism 100 respectively. The splitting and combining mechanism 100 stacks the first sides 10a of the two stacks of sheets 10 facing each other. The grasping mechanism 16 transfers the stacked sheets 10 to the stacking mechanism 12. When a certain number of sheets 10 are accumulated in the stacking mechanism 12, they can be transported to other processing equipment.

[0134] The grasping mechanism 16 is used to transfer the sheets 10 between the stacking mechanism 12 and the splitting and combining mechanism 100, and can be used to grab the sheets 10 according to the size data of the sheets 10 and rotate and stack the sheets 10.

[0135] A control method for a splitting and combining mechanism 100 according to an embodiment of the present invention includes:

[0136] The control separating and combining mechanism 100 stacks multiple separated sheet materials 10 so that the two first surfaces 10a of the two sheet materials after stacking face each other, or, splits the multiple sheet materials 10 stacked together so that the first surfaces 10a of all the sheet materials 10 after splitting face the same direction. In this way, when the separating and combining mechanism 100 works, it can split the stacked sheet materials 10 or stack each sheet material 10, completing the automatic splitting or stacking of the sheet materials 10, which can replace manual operations and improve the automation level of the processing flow.

[0137] The control method of the above-mentioned separating and combining mechanism 100 controls the separating and combining mechanism 100 to stack or split the sheet material 10 with front and back sides, realizing the automatic stacking or splitting of the sheet material 10, which is beneficial to improving the automation level of the processing flow of the sheet material 10 and reducing labor costs.

[0138] Specifically, the sheet material 10 to be split or stacked is transported to the separating and combining mechanism 100, which can be manually carried or the sheet material is transported and grabbed to the separating and combining mechanism 100 through the conveyor line 200.

[0139] When the sheet material 10 needs to be split, the two first surfaces 10a are placed opposite to each other. After the separating and combining mechanism 100 splits the sheet material 10, the two first surfaces 10a can be placed facing the same direction.

[0140] When the sheet material 10 needs to be stacked, the two first surfaces 10a are placed facing the same direction. After the separating and combining mechanism 100 stacks the sheet material 10, the two first surfaces 10a can be stacked opposite to each other, which is beneficial to protecting the first surface of the sheet material 10 during transportation.

[0141] Please refer to Figure 16 , in some embodiments, the control method includes:

[0142] Step S107: As Figure 7 and Figure 10 shown, control the fixing device 30 and the blocking member 34 on the first working platform 26 to fix the stacked sheet material 10 and control the first working platform 26 and the second working platform 28 to switch to the second working position.

[0143] In this way, the first working platform 26 drives the stacked sheet material 10 to the second working position by the grasping mechanism 16, so that splitting can be performed.

[0144] Specifically, the stacked sheet material 10 is placed on the first working platform 26. Control the second driving device to drive the telescopic part 302 to drive the fixing part 301 to move until the fixing part 301 contacts and fixes the second surface 10b of the lower layer sheet material 10. At this time, the stacked sheet material 10 is fixed on the bearing platform 32 of the first working platform 26, and the first working platform 26 and the second working platform 28 switch to the second working position, and the second surface 10b of the upper layer sheet material 10 is close to the second working platform 28.

[0145] Step S109: As Figure 13 shown, control the moving device 40 on the second working platform 28 to drive the second working platform 28 to move until the fixing device 30 on the second working platform 28 contacts and fixes the sheet material 10.

[0146] In this way, by switching between the first working platform 26 and the second working platform 28 between the first working station and the second working station, the splitting of the stacked sheet materials 10 is completed.

[0147] Specifically, at this time, control the moving device 40 to drive the second working platform 28 to move until the fixing device 30 on the second working platform 28 contacts and fixes the second surface 10b of the upper sheet material 10. Among them, the fixing device 30 on the second working platform 28 can also drive the telescopic part 302 to extend through the second driving device so that the fixing part 301 contacts and fixes the second surface 10b of the upper sheet material 10. At this time, the first working platform 26 and the second working platform 28 respectively fix a stack of sheet materials 10.

[0148] Step S111: As Figure 14 shown, control the first working platform 26 and the second working platform 28 to switch to the first working station.

[0149] In this way, the separation of the stacked sheet materials 10 can be realized.

[0150] Specifically, control the first working platform 26 and the second working platform 28 to switch to the first working station, separate the sheet materials 10 respectively fixed on the first working platform 26 and the second working platform 28, and keep each sheet material 10 in a state where the first surface 10a faces upward.

[0151] Before controlling the first working platform 26 and the second working platform 28 to switch to the first working station, the moving device 40 can be controlled to drive the second working platform 28 to move away from the first working platform 26 by a certain distance, so as to avoid interference when the first working platform 26 and the second working platform 28 switch working stations.

[0152] Please refer to Figure 17 , in some embodiments, before step S107, the control method includes:

[0153] Step S1071: Control the conveying device 36 of the first working platform 26 to drive the stacked sheet materials 10 to move until the blocking member 34 of the first working platform 26 limits the position of the stacked sheet materials 10 in the first direction.

[0154] In this way, the sheet materials 10 placed on the first working platform 26 and the second working platform 28 can be moved to a position convenient for splitting and stacking operations, ensuring the smooth progress of subsequent splitting or stacking operations.

[0155] Specifically, the conveying device 36 drives the sheet material 10 to move. After one side of the sheet material 10 contacts the blocking member 34, the conveying device 36 stops working. When switching workstations subsequently, the blocking mechanism can be used to fix and support the side of the sheet material 10 in contact with it, thereby fixing the sheet material 10.

[0156] Please refer to Figure 18 , in some embodiments, after step S111, the control method includes:

[0157] Step S1111: Control the fixing device 30 to release the fixation of the sheet material 10.

[0158] In this way, the sheet material 10 can be moved on the carrying platform 32 for easy adjustment.

[0159] Specifically, the carrying platform 32 is provided with a conveying device 36, and the conveying device 36 can drive the sheet material 10 to move along the first direction on the carrying platform 32. After the fixing device 30 fixes the sheet material 10, the relative movement between the sheet material 10 and the carrying platform 32 is restricted. Therefore, before using the conveying device 36 to adjust the position of the sheet material 10 on the carrying platform 32, it is necessary to control the fixing device 30 to release the fixation of the sheet material 10. In addition, the second driving device of the fixing device 30 can be controlled to drive the telescopic portion 302 to drive the fixing portion 301 to contract, preventing the fixing device 30 from interfering with the movement of the sheet material 10 on the carrying platform 32.

[0160] Step S1113: Control the clapper devices on the first working platform 26 and the second working platform 28 to position the sheet material 10.

[0161] In this way, the sheet material 10 on the carrying platform 32 can be positioned, so that the subsequent grasping mechanism 16 can accurately grasp the sheet material 10.

[0162] Specifically, the first positioning plate 38 and the second positioning plate 39 are respectively arranged on the carrying platform 32 along the third direction and the second direction, and are used for centering and positioning sheet materials 10 of different sizes. After the splitting mechanism 100 completes the splitting of the sheet material 10, the clapper device is used to position the sheet material 10, which is convenient for transportation when the sheet material 10 is transferred to the next process.

[0163] Please refer to Figure 19 , in some embodiments, the control method includes:

[0164] Step S115: Control the fixing devices 30 on the first working platform 26 and the second working platform 28 to respectively fix the sheet material 10.

[0165] In this way, the fixing device 30 fixes the sheet material 10, which is convenient for the first working platform 26 and the second working platform 28 to drive the sheet material 10 to switch workstations.

[0166] Specifically, the gripping mechanism 16 places the sheet material 10 at corresponding positions on the first working platform 26 and the second working platform 28. Before switching the working positions, the fixing device 30 is controlled to fix the sheet material 10 to prevent relative movement between the sheet material 10 and the carrier table 32 during the process of switching the working positions.

[0167] Step S117: Control the first working platform 26 and the second working platform 28 to switch to the second working position, and control the moving device 40 to drive the second working platform 28 to move until the two sheet materials 10 come into contact with each other.

[0168] In this way, the two sheet materials 10 can be stacked together in a state where the first surfaces 10a are in contact with each other.

[0169] Specifically, in the second working position, control the moving device 40 to drive the second working platform 28 to approach the first working platform 26, so that the two sheet materials 10 are stacked together in a state where the first surfaces 10a are in contact with each other.

[0170] Step S119: Control the fixing device 30 on the second working platform 28 to release the fixation of the sheet material 10, and control the first working platform 26 and the second working platform 28 to switch to the first working position.

[0171] In this way, the two sheet materials 10 can return to the first working position with the first working platform 26, completing the stacking of the single-layer sheet materials 10.

[0172] Specifically, the fixing device 30 on the second working platform 28 releases the fixation of the sheet material 10. At this time, the two sheet materials 10 have been stacked together in a state where the first surfaces 10a are in contact with each other. Controlling the first working platform 26 and the second working platform 28 to switch to the first working position can achieve the front-back stacking of the two sheet materials 10.
