[0040] See also Figures 1 to 4 The utility model embodiment provides a conveyor line 100 for a PCB board 10. The board 10 has a first surface 10a and a second surface 10b along a thickness direction. The conveyor line 100 includes a stacking mechanism 12, a separation and combination mechanism 14 and a grabbing mechanism 16.

[0041] The stacking mechanism 12 is used to place the sheet materials 10 .

[0042] The splitting and combining mechanism 14 is used to stack the separated multiple sheets 10 so that the two first surfaces 10a of the two stacked sheets 10 are stacked relative to each other, and to split the stacked multiple sheets 10 so that the first surfaces 10a of all the split sheets 10 face the same direction.

[0043] The gripping mechanism 16 is used to transfer the sheet material 10 between the stacking mechanism 12 and the separating and combining mechanism 14 .

[0044] The conveyor line 100 of the above-mentioned PCB board 10, the separation and combination mechanism 14 is used to stack or split the boards 10 with front and back sides, and the boards 10 are transferred between the stacking mechanism 12 and the separation and combination mechanism 14 through the grasping mechanism 16, so as to realize the automatic stacking or splitting of the boards 10, which is beneficial to improve the automation level of the board 10 processing flow and reduce labor costs.

[0045] 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 holes in the copper clad laminate 20 sheet 10, 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 sheet 10.

[0046] 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.

[0047] 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.

[0048] 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 clamps 17 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, the sheets 10 may fall off or be damaged.

[0049] Based on the above problems, the embodiment of the present invention provides a conveyor line 100 for PCB board 10. 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 plate 20 and an aluminum sheet 22, as shown in FIG. Figure 4 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.

[0050] The splitting and combining mechanism 14 is used to split two sheets 10 whose first surfaces 10a are stacked relative to each other, and keep the first surfaces 10a facing upward at the same time. Alternatively, the splitting and combining mechanism 14 is used to stack the sheets 10 whose first surfaces 10a face upward at the same time, so that the first surfaces 10a of the two sheets 10 are stacked relative to each other.

[0051] When the splitting and combining mechanism 14 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 sheet materials 10 are stacked at 90 degrees and transported to the stacking mechanism. The grabbing mechanism 16 grabs the two stacked sheet materials 10 and places them on the splitting and combining mechanism 14. The splitting and combining mechanism 14 splits the stacked sheet materials 10 and keeps the first surfaces 10a facing upward.

[0052] When the separating and combining mechanism 14 is used to stack the sheets 10, the sheets 10 keep the first side 10a facing upwards, and the grasping mechanism 16 places the sheets 10 on the separating and combining mechanism 14 respectively. The separating and combining mechanism 14 stacks the first sides 10a of two sheets 10 relative to each other, and the grasping 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.

[0053] The gripping mechanism 16 is used to transfer the sheet material 10 between the stacking mechanism 12 and the separation and combination mechanism 14. For example, the gripping mechanism 16 can be a conventional six-axis robot arm, which can adjust the gripping position and angle according to the positions of the sheet material 10, the stacking mechanism 12, and the separation and combination mechanism 14 to complete the transfer. Alternatively, the gripping mechanism 16 can be a four-axis (X-axis, Y-axis, Z-axis, and rotation axis) robot arm, which can be used to grip the sheet material 10 according to the size data of the sheet material 10, and can rotate and stack the sheet material 10.

[0054] Therefore, the sheet material 10 can be split or stacked by the splitting and combining mechanism 14 and transferred between the splitting and combining mechanism 14 and the stacking mechanism 12 by the gripping mechanism 16 , thereby realizing the automatic splitting and transportation of the sheet material 10 .

[0055] In certain embodiments, the separation and combination mechanism 14 includes a first drive device 24, a first working platform 26 and a second working platform 28. The first drive device 24 connects the first working platform 26 and the second working platform 28. The first drive device 24 is used to drive the first working platform 26 and the second working platform 28 to switch between the first workstation and the second workstation to stack or split the sheet material 10. The first drive device 24 drives the first working platform 26 and the second working platform 28 to rotate to switch between the first workstation and the second workstation.

[0056] At the first working position, the first working platform 26 and the second working platform 28 are parallel to each other along a first direction. At the second working position, the first working platform 26 and the second working platform 28 are parallel to each other along a second direction.

[0057] In this way, the stacking or splitting of the sheet material 10 can be achieved by switching the first working platform 26 and the second working platform 28 between the first work station and the second work station.

[0058] Specifically, the splitting and combining mechanism 14 further includes a base 25, and a first working platform 26 and a second working platform 28 are mounted on the base 25. The first working platform 26 and the second working platform 28 are driven by the first driving device 24 to switch between the first workstation and the second workstation. The first working platform 26 and the second working platform 28 are arranged side by side on the base 25. At the first workstation, the first working platform 26 and the second working platform 28 are parallel to each other along the first direction and are parallel to the base 25. At the second workstation, the first working platform 26 and the second working platform 28 are parallel to each other along the second direction and are perpendicular to the base 25.

[0059] It should be noted that the parallel and perpendicular relationships between the above elements may have certain errors within an allowable range.

[0060] The first direction and the second direction are Figure 1 The X-axis direction and the Z-axis direction shown in .

[0061] The first working platform 26 and the second working platform 28 are driven by the first driving device 24 to drive the sheet material 10 placed thereon to switch between the first working station and the second working station.

[0062] like Figure 2 As shown, the first working platform 26 and the second working platform 28 first maintain the first working position, and the gripping mechanism 16 places the sheet materials 10 stacked upside down on the first working platform 26. The first working platform 26 can fix the sheet materials 10 placed thereon and drive the sheet materials 10 and the second working platform 28 to switch to the second working position at the same time. At this time, the second surface 10b of one sheet material 10 is fixed to the first working platform 26, and the second surface 10b of the other sheet material 10 faces the second working platform 28. The second working platform 28 fixes the second surface 10b of the stack of sheet materials 10, and then the first working platform 26 and the second working platform 28 switch to the first working position, which can drive the two sheet materials 10 to separate and keep the first surface 10a of the two sheet materials 10 facing upward.

[0063] like Figure 7 As shown, the first working platform 26 and the second working platform 28 are respectively equipped with a first driving device 24, and the first driving device 24 drives the first working platform 26 to rotate so as to realize the switching between the first working platform 26 and the second working platform 28. By switching the working position in a rotating manner, the first working platform 26 and the second working platform 28 can be switched between the first working position and the second working position simply and smoothly.

[0064] The first driving device 24 may be an electrically driven, hydraulically driven, or pneumatically driven first driving device 24 , and the power source of the first driving device 24 is not limited herein.

[0065] In one embodiment, the first driving device 24 includes a rotary motor. The two rotary motors are respectively installed on the first working platform 26 and the second working platform 28 on the side close to each other, so that the rotary motors can respectively drive the first working platform 26 and the second working platform 28 to rotate, 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.

[0066] In some embodiments, the gripping mechanism 16 includes a clamp 17 and a first vision system 42 , wherein the first vision system 42 is mounted on the clamp 17 , and the first vision system 42 is used to capture an image of the sheet material 10 and obtain position information of the sheet material 10 based on the image of the sheet material 10 .

[0067] In this way, the first visual system 42 is disposed on the clamping jaw 17 , so that the clamping jaw 17 can obtain the position information of the sheet material 10 , thereby accurately grasping the sheet material 10 .

[0068] Specifically, Figure 5 As shown, before the gripping mechanism 16 grips the sheet material 10, it first obtains the position information of the sheet material 10 to be operated. The position information includes the front and back of the top sheet material 10 in the stack of sheets 10, as well as the height, position and angle of the stacked sheets 10, so that the gripping mechanism 16 can accurately grip the sheet material 10.

[0069] The first visual system 42 can determine the position information such as the inclination angle of the sheet 10 and the front and back of the top sheet 10 by determining the position and direction of the pins of the top layer of the stacked sheets 10 or the size (long and short sides) of the top sheet 10 .

[0070] The grabbing mechanism 16 may obtain the position information of the sheet material 10 once before grabbing the sheet material 10 each time. Alternatively, the position information of the sheet material 10 may be updated once when the size of the sheet material 10 placed on the stacking mechanism 12 is changed.

[0071] After obtaining the position information of the sheet 10, the grasping mechanism 16 is controlled to grasp the sheet 10. For example, the grasping mechanism 16 is a mechanical arm with a clamping claw. According to the position information of the sheet 10, the mechanical arm drives the clamping claw 17 to move to the height position of the sheet 10, opens the clamping claw 17, and grasps the sheet 10. When grasping the sheet 10, the mechanical arm first obtains the position information and size information of the sheet 10, descends to the corresponding height, extends the clamping claw to a distance wider than the width of the sheet 10 to contact the sheet 10 and gradually retracts, thereby grasping the sheet 10.

[0072] Since the sheets 10 are stacked up two by two and placed at 90 degrees between each other, after the robot arm grabs the sheet 10 once, it needs to rotate 90 degrees for the next grab.

[0073] The grabbing mechanism 16 places the two sheets 10 stacked up front and back on the first working platform 26 at the same time, and can place the surfaces of the two aluminum sheets 22 at the junction without relative movement or with little relative movement, thereby preventing the surfaces of the aluminum sheets 22 from being damaged.

[0074] In one embodiment, the position information of the sheet material 10 may be stored in advance in the control device, and the sheet material 10 to be operated is transported to a preset position each time to ensure the accuracy of the position information stored in the control device.

[0075] In one embodiment, a first visual system 42 , such as an industrial 3D camera, an industrial 2D camera, etc., is provided on the gripping mechanism 16 to obtain the position information of the sheet material 10 in real time so as to facilitate the gripping mechanism 16 to accurately grip the sheet material 10 .

[0076] See also Figure 6 In some embodiments, the conveyor line 100 includes a loading platform 44, which is used to place the split single plate material 10 and transfer it to the processing equipment.

[0077] In this way, the stacked plates 10 can be automatically split and automatically loaded, thereby improving the automation level of the production process.

[0078] Specifically, after the stacked sheets 10 are separated, they can be directly transferred to the loading platform 44 by the gripping device, and the loading platform loads the separated sheets 10 to the subsequent processing equipment. Therefore, the conveyor line 100 replaces manual labor to separate the sheets 10 stacked on both sides before processing, and the conveyor line 100 is set as a link in the automated processing flow, thereby improving the automation level of the PCB sheet 10 processing process.

[0079] See also Figure 7 In some embodiments, the conveyor line 100 includes a silo 46 for storing the split individual panels 10 .

[0080] In this way, it is convenient to distinguish and transport the panels 10 .

[0081] Specifically, the conveyor line 100 includes a silo 46, which is used to store split individual sheets 10. The stacked sheets 10 are placed in the stacking mechanism 12, and the individual sheets 10 are placed in the silo 46, which can facilitate the grabbing mechanism 16 to distinguish and grab the sheets 10, and at the same time facilitate the second material changing mechanism 58 to transport the sheets 10.

[0082] In the illustrated embodiment, the stacking mechanism 12 and the silo are respectively arranged on both sides of the separation and combination mechanism 14. When the separation and combination mechanism 14 is used to separate the stacked sheet materials 10, the gripping mechanism 16 grabs the stacked sheet materials 10 in the stacking mechanism 12. When the separation and combination mechanism 14 is used to stack individual sheet materials 10, the gripping mechanism 16 grabs the stacked sheet materials 10 in the silo 46. In subsequent processing, the sheet materials 10 can also be taken from different positions according to different requirements.

[0083] In some embodiments, the silo 46 includes a first bracket 48, at least one storage layer 50 and a second driving device 52. The storage layer 50 is movably mounted on the first bracket 48. The driving device is mounted on the storage layer 50. The second driving device 52 is used to drive the storage layer 50 to drive the sheet material 10 to move in the second direction. The storage layer 50 is used to place the split single sheet material 10.

[0084] In this way, the separated individual sheets 10 can be automatically stored in the silo 46 , which is convenient for the storage and transportation of the sheets 10 .

[0085] Specifically, the silo 46 includes a first bracket 48, at least one storage layer 50, and a second driving device 52. The storage layer 50 is arranged on the first bracket 48, and the second driving device 52 can drive the storage layer 50 to move in the second direction on the first bracket 48. The storage silo is used to place the split single sheet 10. After the sheet 10 is split, the sheet 10 can be transferred to the silo 46 by the conveying device 36 on the carrier 32. The second driving device 52 controls the storage layer 50 to be flush with the carrier 32 or slightly lower than the carrier 32, so that the conveying device 36 can send the sheet 10 into the storage layer 50.

[0086] See also Figure 7 and Figure 8 In one embodiment, the number of storage layers 50 is more than two. After the sheet material 10 is stored in each storage layer 50, the second driving device 52 controls the storage layer 50 to move up or down as a whole, and aligns the storage layer 50 without the sheet material 10 with the position of the supporting platform 32. In this way, the silo 46 can automatically collect the split single sheet material 10.

[0087] In some embodiments, the storage layer 50 includes a second bracket 54 and a power device 56 . The power device 56 is installed on the second bracket 54 . The second bracket 54 is used to place the sheet material 10 . The power device 56 is used to provide power for the sheet material 10 to enter and exit the second bracket 54 .

[0088] In this way, the silo 46 can automatically recycle and release the sheet material 10 .

[0089] Specifically, Figure 8As shown, the second bracket 54 of the storage layer 50 is used to support and place the sheet material 10. The second bracket 54 is used to place the sheet material 10. The power device 56 is arranged on the second bracket 54, which can make the sheet material 10 enter the second bracket 54 or make the sheet material 10 exit from the second bracket 54. After the splitting and combining mechanism 14 splits the sheet material 10, it is transferred to the silo 46. The power device 56 can drive the sheet material 10 to move and enter the storage layer 50. In addition, a single sheet material 10 can also be placed in the silo 46 after processing in other processes. When the splitting mechanism is used to stack the sheet material 10, the power device 56 works to drive the sheet material 10 to exit the storage layer 50 and move to the bearing platform 32 of the first working platform 26 and the second working platform 28, so as to realize automatic loading.

[0090] For example, the power device 56 may be a transmission belt disposed on the second bracket 54 , which may drive the sheet material 10 to move into or out of the storage layer 50 .

[0091] In some embodiments, the silo 46 includes a first material changing mechanism (not shown), and the first bracket 48 is disposed on the first material changing mechanism. The first material changing mechanism is used to drive the silo 46 to move so as to transfer a single sheet material 10 between a preset position and other positions of the silo 46.

[0092] In this way, the material bin 46 can realize automatic loading and unloading.

[0093] Specifically, the first material changing mechanism is used to drive the silo 46 to move. In the process of splitting the stacked sheet materials 10, the individual sheet materials 10 split by the splitting and combining mechanism 14 are stored in the silo 46. After a certain number of sheets are stored, the first material changing mechanism drives the silo 46 to move to the next process to realize automatic unloading of the silo 46.

[0094] In the process of stacking single sheets 10, the single sheets 10 enter the separation and combination mechanism 14 from the silo 46 for splitting. The first material changing mechanism can move the silo 46 storing the single sheets 10 to a preset position, so that the silo 46 can transport the single sheets 10 to the separation and combination mechanism 14, thereby realizing automatic loading of the silo 46.

[0095] In some embodiments, the stacking mechanism 12 includes a third bracket 60 and a tray 62 . The tray 62 is movably placed on the third bracket 60 , and the tray 62 is used to place the stacked sheets 10 .

[0096] In this way, the stacked sheets 10 can be transported in batches using the pallet.

[0097] Specifically, the stacking mechanism 12 includes a third bracket 60 and a tray 62, the tray 62 is movably placed on the third bracket 60, and the sheets 10 are stacked in the tray 62. The tray 62 can be used to transport the stacked sheets 10 in batches, which is convenient for taking and placing the sheets 10 when transferring the sheets 10.

[0098] See also Figure 5 In some embodiments, the stacking mechanism 12 includes a second material changing mechanism 58, which is used to drive the pallet 62 to move so as to transfer the stacked sheet materials 10 between the stacking mechanism 12 and other locations.

[0099] In this way, the stacked sheets 10 can be automatically transferred between the stacking mechanism 12 and other locations, thereby improving work efficiency.

[0100] Specifically, the second material changing mechanism 58 can transport the stacked sheet materials 10 to the stacking mechanism 12 , or transfer the sheet materials 10 on the stacking mechanism 12 to other locations, so as to realize automatic loading and unloading of the sheet materials 10 .

[0101] In the process of splitting the stacked sheets 10, the stacked sheets 10 are placed in the tray 62 of the stacking mechanism 12, and the sheets 10 are split by the splitting and combining mechanism 14. After the sheets 10 in the stacking mechanism 12 are transferred and split, the second material changing mechanism 58 can transport the sheets to be split from other locations to the stacking mechanism 12, so that the stacking mechanism 12 can be automatically loaded.

[0102] In the process of stacking individual sheets 10 , the sheets 10 stacked by the separation and combination mechanism 14 are placed on the stacking mechanism 12 . A certain number of sheets 10 are accumulated on the stacking mechanism 12 and are transferred to other locations by the second material changing mechanism 58 , so that the material bin 46 can be automatically unloaded.

[0103] The second material changing mechanism 58 includes but is not limited to AGV (Automated Guided Vehicle), forklift, electric transport vehicle and the like.

[0104] In one example, the second material changing mechanism 58 is an AGV, so that the AGV drives the pallet 62 and the sheets 10 stacked on the pallet 62 to move, and positioning parts are set at the corresponding positions of the pallet and the third bracket 60, so that the AGV can place the pallet and the sheets 10 at the preset positions on the third bracket 60, thereby completing the transfer of the sheets 10 between other positions and the stacking mechanism 12.

[0105] In some embodiments, the stacking mechanism 12 includes a second visual system 43 , which is disposed on the third bracket 60 . The second visual system 43 is used to capture an image of the sheet material 10 and obtain position information of the sheet material 10 based on the image of the sheet material 10 .

[0106] In this way, the position information of the sheet material 10 can be determined according to the second visual system 43 , thereby helping the grasping mechanism 16 to grasp the sheet material 10 accurately.

[0107] Specifically, the second visual system 43 can be used to determine the front and back of the top sheet 10 in the stacked sheets 10, and identify the height, position and angle of the front and back stacked sheets 10 and send the above data information to the grasping mechanism 16. The grasping mechanism 16 moves to the corresponding position according to the data information of the sheet 10 and grasps the sheet 10.

[0108] At the same time, the second visual system 43 can also confirm whether the sheet material 10 has been placed on the tray 62 of the current stacking mechanism 12. Based on this information, the second material changing mechanism 58 can be controlled to transfer and replenish the sheet material 10 in time.

[0109] The second visual system 43 is also used to determine the front and back of the top sheet 10. If the top sheet 10 is facing up, the top sheet 10 is a single sheet 10 and does not need to be split. The grasping mechanism 16 can directly transfer it to the next process.

[0110] In one embodiment, the second visual system 43 can judge the front and back of the sheet material 10 by identifying the material of the side of the sheet material 10 facing upward. For example, a sheet material 10 is stacked in the order of a backing plate 18, a copper-clad plate 20, and an aluminum sheet 22, wherein the backing plate 18 is generally made of wood. By identifying the material of the side of the sheet material 10 facing upward, if it is made of wood, it is judged that the back of the sheet material 10 faces upward, and two sheets 10 are stacked. If it is made of metal, it is judged that the front of the sheet material 10 faces upward, and it is a single sheet material 10, and there is no need to split it.

[0111] In one embodiment, the second visual system 43 can judge the front and back of the sheet 10 by judging the position of the pins on the sheet 10. The sheet 10 is stacked in the order of the pad 18, the copper-clad plate 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, and on the side of the pad 18, the pin extends out to a certain length. The protruding height of the pin relative to the upper side of the sheet 10 is judged. If there is a protruding height, it is judged that the back side of this sheet 10 is upward, and two sheets 10 are stacked. If there is no or basically no protruding height, it is judged that the front side of this sheet 10 is upward, and it is a single sheet 10, and there is no need to split it.

[0112] In one embodiment, the second visual system 43 is an industrial 3D camera, which can obtain the distance from the camera to each point on the surface of the object, perceive the shape and contour of the object, and thus obtain the position information and size parameters of the sheet material 10.

[0113] In one embodiment, the second vision system 43 is an industrial 2D camera and is equipped with a distance measurement sensor to achieve functions similar to those of an industrial 3D camera.

[0114] To summarize, the separating and combining mechanism 14 is used to stack or split the sheets 10 with the front and back sides. When splitting the stacked sheets 10, the grabbing mechanism 16 simultaneously grabs the two sheets 10 stacked on the front and back sides. The two sheets 10 are placed on the separating and combining mechanism 14, and are vertically and separated along the second direction, thereby realizing the splitting of the stacked sheets. At the same time, it can ensure that there is no relative movement or the relative movement is very small between the two sheets 10, thereby preventing damage to the surface of the sheets 10 and preventing the tape fixing the sheets 10 from falling off.

[0115] The sheet material 10 is transferred between the stacking mechanism 12 and the separation and combination mechanism 14 by the gripping mechanism 16, so as to realize the automatic stacking or splitting of the sheet material 10, which is beneficial to improve the automation level of the sheet material 10 processing flow and reduce labor costs.

[0116] Through the loading mechanism 44, the conveyor line 100 can automatically split the stacked sheet materials 10 and automatically load them, thereby improving the automation level of the production process.

[0117] The silo 46 can be used to automatically store the split sheet materials 10 , or automatically feed a single sheet material 10 to the splitting and combining mechanism 14 or other processing equipment, thereby improving the automation level of the conveyor line 100 .

[0118] The second material changing mechanism 58 can realize automatic transfer of the stacked sheet materials 10 between the conveyor line 100 and other locations, thereby improving operation efficiency.
