Description

Technical Field

[0001] This application relates to the field of automated transportation equipment technology, specifically a sheet metal transfer device. Background Technology

[0002] Materials, such as PCBs, undergo numerous processing and testing steps before being manufactured into finished products. Due to these different steps, they need to move between different processing workshops, processing equipment, and testing devices. For example, after one process is completed, the processed boards are collected one by one into a board material box. Then, the board material box is moved to the next production unit, where the boards are individually removed.

[0003] However, due to subsequent production cost control or generalization considerations, a simplified pallet was added to the existing sheet material boxes as a transit and loading device. The sheet material boxes have multiple layers; the sheets are placed inside, with each layer separated to prevent stacking and scratching. The simplified pallet simply stacks sheets one layer and a pallet the next. For more valuable sheets, the sheet material boxes are still used as the transit and loading device.

[0004] Furthermore, the movement patterns of sheet metal differ when it is handled by two types of transfer devices: sheet metal boxes and simplified pallets. Therefore, there is an urgent need to improve the transfer device that receives the transfer devices to adapt to both types of transfer devices and automate the process of picking up and placing sheet metal from the transfer devices onto the subsequent processing or inspection line.

[0027] Please refer to Figures 1-5 This embodiment provides a sheet metal transfer device, including: The frame 1 is provided with a first feeding area 110, a second feeding area 120, and a receiving area 130; the first feeding area 110 and / or the second feeding area 120 are provided with a board material retraction and unfolding drive device 2 corresponding to the board material box; A board material box, also known as a material frame.

[0028] Lifting device 3, there are two sets of lifting devices 3, respectively set in the first feeding area 110 and the second feeding area 120; the power output end of the lifting device 3 is provided with a bracket 4; the bracket 4 is used to support the material box or simplified pallet; the lifting device 3 is used to drive the bracket 4 to move along the height direction; A receiving module 5 is disposed in the receiving area 130; the receiving area 130 is matched with the first feeding area 110 and the second feeding area 120 and is provided with a first receiving position 131 and a second receiving position 132; the receiving module 5 includes a shifting linear module 510 and a conveyor line 520 installed at the power output end of the shifting linear module 510; the shifting linear module 510 is used to drive the conveyor line 520 to move to the first receiving position 131 or the second receiving position 132. The shifting linear module 510 can be a drive device consisting of a motor-driven lead screw and nut pair and a guide rail slide.

[0029] A transplanting module is installed on the upper end of the frame 1, and a hoisting device is provided at the power output end of the transplanting module; the transplanting module is used to drive the hoisting device to move between the first feeding area 110 and the first receiving position 131, or to drive the hoisting device to move between the second feeding area 120 and the second receiving position 132. When the bracket 4 supports the board material box, the lifting device 3 drives the bracket 4 and the board material box to move to a predetermined height. Then, the board material unfolding drive device 2 connects with the board material box power receiving part 9 and drives the board material box to be output to the conveyor belt of the conveyor line 520. When the bracket 4 supports the simplified pallet, the lifting device 3 drives the bracket 4 and the simplified pallet to move to a predetermined height. Then, the transplanting module drives the hoisting device to lift the upper plate of the simplified pallet and transfer the plate to the conveyor belt of the conveyor line 520.

[0030] Operating principle: Example 1 There are two transplanting modules, and the two transplanting modules can have the same structure. Specifically, the first transplanting module 6 is provided with a first hoisting device 7 at the power output end of the first transplanting module 6. The first transplanting module 6 is used to drive the first hoisting device 7 to move between the first feeding area 110 and the first receiving position 131. The second transplanting module 8 has a second hoisting device 13 at its power output end; the second transplanting module 8 is used to drive the second hoisting device 13 to move between the second feeding area 120 and the second receiving position 132. The first transplanting module 6 and the second transplanting module 8 are both installed on the upper end of the frame 1.

[0031] In the receiving module 5, the conveyor line 520 has been pre-moved to the first receiving position 131 under the drive of the transposition linear module 510.

[0032] The board material box is placed in the feeding area equipped with a board material retraction drive device 2 via external transportation. For example, both the first feeding area 110 and the second feeding area 120 have board material retraction drive devices 2. The board material box is then placed on the bracket 4 of the first feeding area 110. The bracket 4 of the second feeding area 120 can hold another board material box or a simplified pallet. In this example, a simplified pallet for loading board materials is placed on the bracket 4 of the second feeding area 120.

[0033] The lifting device 3 drives the bracket 4 in the first feeding area 110 to a predetermined height, and the board material unfolding drive device 2 drives a layer of board material in the board material box to unfold and be sent out of the board material box in the direction of unfolding and sending out towards the first receiving position 131. At this time, the board material sent out is just received by the conveyor line 520 at the first receiving position 131.

[0034] The sheet material falls onto the conveyor belt of conveyor line 520 and is transported by conveyor line 520 to the subsequent workstation. At the same time, the sheet material unfolding drive device 2 moves to avoid obstruction, and the lifting device 3 drives the bracket 4 to rise and fall to the height of the next receiving layer containing sheet material. This cycle of conveying sheet material layer by layer in the material box is repeated until the conveying is completed.

[0035] When all the boards in the material box of the first feeding area 110 have been removed, the shifting linear module 510 is used to drive the conveyor line 520 to move laterally to the second receiving position 132.

[0036] The padding on the simplified pallet in the second feeding area 120 is removed manually or by external automated equipment, exposing the top layer of the simplified pallet. The second transfer module 8 drives the second hoisting device 13 to move to the second feeding area 120, above the simplified pallet; Then, the second hoisting device 13 is driven to descend, connecting and lifting the top plate of the simplified pallet. Next, the second transfer module 8 drives the second hoisting device 13 to rise and move it above the second receiving position 132. Then, the second hoisting device 13 is driven to descend, releasing the lifted plate, which falls onto the conveyor belt of the conveyor line 520 and is transported to the subsequent workstation. Simultaneously, the top plate of the simplified pallet in the second feeding area 120 is removed manually or by external automated equipment, and the lifting device 3 drives the bracket 4 to rise to a height suitable for the second hoisting device 13 to pick up the material. This cycle of transferring layers of plates on the simplified pallet continues.

[0037] In some embodiments, since the material box and simplified pallet need to be driven by the lifting device 3 to adjust the feeding height after each piece of material is taken away, during the interval when the lifting device 3 is adjusting the height, the conveyor line 520 can be driven by the shifting linear module 510 to move to the first receiving position 131 or the second receiving position 132 to receive the material that can be directly and conveniently sent from another feeding area. The two intermediate carriers, the first feeding area 110 and the second feeding area 120, alternately supply materials, thereby improving the transfer efficiency.

[0038] Example 2 In this example, a simplified pallet for loading sheet material is placed on the bracket 4 of the first feeding area 110. A simplified pallet for loading sheet material is also placed on the bracket 4 of the second feeding area 120.

[0039] In the receiving module 5, the conveyor line 520 has been pre-moved to the first receiving position 131 under the drive of the transposition linear module 510.

[0040] The padding on the simplified pallet in the first feeding area 110 is removed manually or by external automated equipment, exposing the top layer of material on the simplified pallet. The first transfer module 6 drives the first hoisting device 7 to move to the first feeding area 110, above the simplified pallet. Then, the first hoisting device 7 is driven to descend, connecting and lifting the top plate of the simplified pallet. Next, the first transfer module 6 drives the first hoisting device 7 to rise and move it above the first receiving position 131. Then, the first transfer module 6 drives the first hoisting device 7 to descend, releasing the lifted plate, which falls onto the conveyor belt of the conveyor line 520 and is transported to the subsequent workstation. Simultaneously, the top plate of the simplified pallet in the first feeding area 110 is removed manually or by external automated equipment, and the lifting device 3 drives the bracket 4 to rise to a height suitable for the first hoisting device 7 to pick up the material. This cycle of transferring plates layer by layer on the simplified pallet in the first feeding area 110 continues until the transfer is complete.

[0041] Once all the boards on the simplified pallet in the first feeding area 110 have been removed, the transposition linear module 510 drives the conveyor line 520 to move laterally to the second receiving position 132.

[0042] The padding on the simplified pallet in the second feeding area 120 is removed manually or by external automated equipment, exposing the top layer of the simplified pallet. The second transfer module 8 drives the second hoisting device 13 to move to the second feeding area 120, above the simplified pallet; Then, the second hoisting device 13 is driven to descend, connecting and lifting the top plate of the simplified pallet. Next, the second transfer module 8 drives the second hoisting device 13 to rise and move it above the second receiving position 132. Then, the second transfer module 8 drives the second hoisting device 13 to descend, releasing the lifted plate, which falls onto the conveyor belt of the conveyor line 520 and is transported to the subsequent workstation. Simultaneously, the top plate of the simplified pallet in the second feeding area 120 is removed manually or by external automated equipment, and the lifting device 3 drives the bracket 4 to rise to a height suitable for the second hoisting device 13 to pick up the material. This cycle of transferring plates layer by layer on the simplified pallet in the second feeding area 120 is repeated.

[0043] In some embodiments, since the simplified pallet needs to be driven by the lifting device 3 to adjust the feeding height after each board is removed, during the interval when the lifting device 3 is adjusting the height, the conveyor line 520 can be driven by the shifting linear module 510 to move to the first receiving position 131 or the second receiving position 132 to receive the board that can be directly and conveniently sent from another feeding area. The two simplified pallets in the first feeding area 110 and the second feeding area 120 alternately supply materials, thereby improving the transfer efficiency.

[0044] Example 3 In this example, the tray 4 in the first feeding area 110 is used to place the board material box containing the board material. The tray 4 in the second feeding area 120 is also used to place the board material box containing the board material. Both the first feeding area 110 and the second feeding area 120 are equipped with a board material unfolding and retracting drive device 2.

[0045] In the receiving module 5, the conveyor line 520 has been pre-moved to the first receiving position 131 under the drive of the transposition linear module 510.

[0046] The lifting device 3 drives the bracket 4 in the first feeding area 110 to a predetermined height, and the board material unfolding drive device 2 drives a layer of board material in the board material box to unfold and be sent out of the board material box in the direction of unfolding and sending out towards the first receiving position 131. At this time, the board material sent out is just received by the conveyor line 520 at the first receiving position 131.

[0047] The sheet material falls onto the conveyor belt of conveyor line 520 and is transported by conveyor line 520 to the subsequent workstation. At the same time, the sheet material unfolding drive device 2 moves to avoid obstruction, and the lifting device 3 drives the bracket 4 to rise and fall to the height of the next receiving layer containing sheet material. This cycle of conveying sheet material layer by layer in the material box is repeated until the conveying is completed.

[0048] When all the boards in the material box of the first feeding area 110 have been removed, the shifting linear module 510 is used to drive the conveyor line 520 to move laterally to the second receiving position 132.

[0049] The lifting device 3 drives the bracket 4 in the second feeding area 120 to a predetermined height, and the board unfolding drive device 2 drives a layer of board material in the board material box to unfold and be sent out of the board material box in the direction of the unfolding and sending out is towards the second receiving position 132. At this time, the board material sent out is just received by the conveyor line 520 at the second receiving position 132.

[0050] The sheet material falls onto the conveyor belt of conveyor line 520 and is transported by conveyor line 520 to the subsequent workstation. At the same time, the sheet material unfolding drive device 2 moves to avoid obstruction, and the lifting device 3 drives the bracket 4 to rise and fall to the height of the next receiving layer containing sheet material. This cycle of conveying sheet material layer by layer in the material box is repeated until the conveying is completed.

[0051] In some embodiments, since the feeding height needs to be adjusted by the lifting device 3 after each board is removed from the board material box, the conveyor line 520 can be moved to the first receiving position 131 or the second receiving position 132 by the switching linear module 510 during the interval of the height adjustment by the lifting device 3 to receive the board that can be directly and conveniently sent from another feeding area. The two board material boxes of the first feeding area 110 and the second feeding area 120 are fed alternately, thereby improving the transfer efficiency.

[0052] Example 4 In this embodiment, there is one transplanting module, and the power output end of the transplanting module is equipped with a hoisting device.

[0053] A simplified pallet for loading sheet material is placed on the bracket 4 of the first feeding area 110. A simplified pallet for loading sheet material is also placed on the bracket 4 of the second feeding area 120.

[0054] The transplanting module can move relative to the frame 1 and move above the first feeding area 110 and the first receiving position 131. The transplanting module drives the hoisting device to move the board from the first feeding area 110 to the corresponding docking conveyor line 520 of the second feeding area 120.

[0055] The transplanting module can move relative to the frame 1 and move above the second feeding area 120 and the second receiving position 132. The transplanting module drives the hoisting device to move the board from the second feeding area 120 to the corresponding docking conveyor line 520 of the second receiving position 132.

[0056] As can be seen from the above embodiments, when the transfer carrier in the feeding area is a sheet material box, the sheet material unfolding drive device 2 is needed to assist in sending the sheet material out of the sheet material box, and the transfer module and hoisting device are not needed. When the transfer carrier in the feeding area is a simplified pallet, the transfer module and hoisting device are needed to assist in hoisting and handling, and the sheet material unfolding drive device 2 is not needed.

[0057] In some embodiments, to avoid the subsequent conveyor belt connected to the conveyor line 520 being too wide, after each material is received by the conveyor line 520, the shifting linear module 510 can move the conveyor line 520 to a position between the first receiving position 131 and the second receiving position 132, and then the conveyor line 520 can start to transfer the material to the connected conveyor belt.

[0058] The first feeding zone 110 and the second feeding zone 120 are arranged in parallel.

[0059] Please refer to Figure 1 and Figure 2 The sheet material unfolding and retracting drive device 2 is located at one corner of the first feeding area 110 and / or the second feeding area 120; the sheet material unfolding and retracting drive device 2 includes a first horizontal transplanter 210, a second horizontal transplanter 220 installed at the power output end of the first horizontal transplanter 210, and a rotary driver 230 installed at the power output end of the second horizontal transplanter 220. The rotary driver 230 is provided with a twisting head 240 at its power output end; after the twisting head 240 is aligned with the power receiving part 9 of the material box, it is driven to rotate by the rotary driver 230, thereby unfolding and retracting the sheet material relative to the sheet material box.

[0060] The board material box is an internal device of a competitor and is not the focus of this application's innovation. The technical solution of rotating the power receiving unit 9 to drive the board material into or out of the board material box will not be described in detail here.

[0061] Please refer to Figure 1 and Figure 2 The first horizontal transplanter 210 and the second horizontal transplanter 220 are both drive cylinders, and the piston rods of the two are perpendicular in extension and retraction direction; the rotary drive 230 is a motor.

[0062] The two drive cylinders can drive the rotary driver 230 to move in two horizontal directions, so that the turning head 240 is aligned with the power receiving unit 9 or moved away from it.

[0063] After the screwing head 240 is aligned and connected with the power receiving unit 9, when the lifting device 3 needs to drive the bracket 4 and the material box to the height of the next layer containing the material, only one of the two driving cylinders can retract its piston rod to avoid the position, while the other driving cylinder remains stationary. In this way, when the screwing head 240 is aligned and connected with the power receiving unit 9 next time, only the driving cylinder whose piston rod retracts to avoid the position needs to extend and reset the piston rod to complete the rapid alignment.

[0064] Please refer to Figure 2 The screwing head 240 is a cylinder with a cross groove 241 on its end face; the end of the cylinder is chamfered 242.

[0065] The power receiving unit 9 is in the shape of a double fork. When the screwing head 240 is docked with the power receiving unit 9, the screwing head 240 is driven to rotate by the rotary driver 230 motor. During the rotation, the double fork-shaped power receiving unit 9 enters the cross groove 241 and is driven to rotate.

[0066] Before the material box is driven by the lifting device 3 to adjust the layer height, the first horizontal transplanter 210 and the second horizontal transplanter 220 of the driving cylinder adjust the position of the rotary driver 230 and the turning head 240 to avoid misalignment.

[0067] Please refer to Figure 5 The bracket 4 has alignment pushers 10 arranged around its side.

[0068] The side of bracket 4 that receives incoming materials has an open structure.

[0069] The alignment pusher 10 is located on the edge of the bracket 4, which has a frame. After the board material box or simplified pallet is placed on the bracket 4, the alignment pusher 10 pushes out a predetermined stroke to the board material box or simplified pallet to perform positioning. The alignment pusher 10 can be a drive cylinder or a linear electric cylinder.

[0070] Please refer to Figure 1 and Figure 5The lifting device 3 includes a lead screw 310, a lifting motor 320 that drives the lead screw 310 to rotate, a support guide rod 330, and a connecting frame 340 that connects the lifting motor 320 and the support guide rod 330; the connecting frame 340 is connected to the frame 1; the bracket 4 is provided with a connecting nut hole (not shown) that matches the lead screw 310; the bracket 4 is also provided with a sliding hole (not shown) that is slidably connected to the support guide rod 330.

[0071] Please refer to Figure 5 The bracket 4 is provided with a positioning sensor 11, and the frame 1 is equipped with a positioning sensor 12 that matches the positioning sensor 11.

[0072] The positioning sensor 11 is a vertically placed slat with multiple regular notches. The positioning sensor 12 collects information about the notches it passes through and uploads it to the host computer. The host computer then determines and controls the lifting motor 320 to operate, so that the bracket 4 is raised or lowered to the precise position.

[0073] Please refer to Figure 1 and Figure 3 The two feed inlets of the first feed zone 110 and the second feed zone 120 face opposite directions.

[0074] The first feeding zone 110 and the second feeding zone 120 constitute a sheet material transfer device capable of receiving material from two intermediate transfer carriers. When the sheet material supplied by the intermediate transfer carrier in one of the feeding zones 110 and 120 is completely removed, the system can directly switch to the intermediate transfer carrier in the other feeding zone to retrieve the sheet material. After switching, an empty intermediate transfer carrier can be replaced with a new intermediate transfer carrier fully loaded with sheet material to be retrieved. This does not affect the ongoing sheet material retrieval process. It achieves seamless connection, avoids downtime due to material shortages, and improves production efficiency.

[0075] By having the two feed inlets facing opposite directions, this setup can improve the safety of the device.

[0076] Please refer to Figure 1 The first hoisting device 7 and the second hoisting device 13 are both hoisting suction cups; the driving direction of the shifting linear module 510 is perpendicular to the conveying direction of the conveying line 520; the conveying line 520 is provided with limiting fences 530 on both sides; the first transplanting module 6 is used to drive the first hoisting device 7 to move in a direction parallel to the second transplanting module 8 is used to drive the second hoisting device 13 to move in a direction parallel to the direction of the first transplanting device 7.

[0077] Please refer to Figure 3 and Figure 5 It includes a tray 14, which is detachably connected to the bracket 4.

[0078] The material box itself has a complete and flat bottom plate, so when it sits on the bracket 4, the tray 14 is not needed. The tray 14 can be removed, and the automated intelligent trolley can easily load the material box onto the bracket 4.

[0079] In some embodiments, the simplified tray is made of plastic. In order to extend its service life and prevent the bracket 4 from supporting only the three sides of the bottom of the simplified tray, with some parts suspended and unevenly stressed, a tray plate 14 is provided on the bracket 4.

[0080] Please refer to Figure 1 and Figure 3 A rotary motor 15 is provided between the transplanting module and the hoisting device, and the rotary motor 15 is used to drive the hoisting device to rotate to a predetermined angle.

[0081] In some embodiments, the discharge port of conveyor line 520 is also connected to a flipping assembly (not shown), which is used to flip the sheet 180° and adjust it before conveying it to the subsequent conveyor line. This ensures that the front and back sides of the sheet face in the same direction as the requirements of subsequent processes.

[0082] In some embodiments, an automated guided vehicle delivers the transfer carrier to the bracket 4. The number of stacks of sheet metal arriving in the transfer carrier is determined by manual intervention or by parameters issued by the MES system. The host computer system, in conjunction with a visual recognition device or with orientation information already included in the parameter information, determines the orientation of the top sheet metal along its length and the orientation of its front and back sides based on the total number of stacks.

[0083] In multi-layered boards within a board material box, the orientation is generally consistent, which is more standardized; however, there may be instances where the front and back orientations are inconsistent. When simplifying multi-layered boards on a pallet, the orientation between each layer may be inconsistent. For example, if the board outline is rectangular, different layers may be placed at 90° angles along their length. Inconsistent front and back orientations may also occur.

[0084] Then, after the hoisting device is used to lift the sheet material whose length direction does not meet the requirements, the rotary motor 15 drives the hoisting device and the sheet material to rotate 90° together for adjustment, so that the sheet material can fall into the receiving area of ​​the conveyor line 520, which is surrounded and limited by the limiting fence 530. At the same time, it also makes the end of the sheet material oriented correctly.

[0085] If the board material still has issues with the orientation of its front and back sides not meeting the requirements, then conveyor line 520 will transport it to the flipping assembly for a 180° rotation adjustment. This ensures that the final output board material meets the requirements in terms of both length orientation and front and back side orientation.

[0086] If the material in the transfer carrier meets the requirements in terms of both length direction and orientation, then it can be taken from the transfer carrier, placed in the receiving area of ​​conveyor line 520, and transported to the subsequent workstation without the need for operation and adjustment using rotary motor 15 and flipping assembly.
