Description

Technical Field

[0001] This application relates to the field of motherboard stacking and bundling, specifically to a stacking and bundling device. Background Technology

[0002] In the after-sales repair process of mobile phone motherboards, there is a station for packaging scrapped motherboards, which requires bundling motherboards in a certain number and then packing them into boxes.

[0003] When packaging motherboards, workers usually manually stack multiple motherboards of the same size to align them, and then manually bundle the stack together, which is inefficient. Summary of the Invention

[0004] In view of this, it is necessary to provide a stacking and bundling device capable of stacking and bundling workpieces.

[0005] One embodiment of this application provides a stacking and bundling device, including a feeding unit, a transfer unit, a stacking unit, a bundling unit, and an unloading unit. The feeding unit is used to provide workpieces; the transfer unit includes a translation mechanism, a rotation mechanism, and grippers connected in sequence. The grippers are used to grasp the workpieces, the rotation mechanism is used to rotate the grippers, and the translation mechanism is used to translate the grippers; the stacking unit includes a support platform, a fixed component, and a movable component. The support platform is used to support the workpieces grasped by the grippers from the feeding unit, so that multiple workpieces form a stack. The fixed component and the movable component are respectively arranged on opposite sides of the support platform to limit the stacking. The movable component can move relative to the fixed component to adjust the distance between the movable component and the fixed component; the bundling unit is used to receive the stacks grasped by the grippers from the stacking unit and bundling the stacks, and is also used to receive the stacks grasped by the grippers from the bundling unit, and bundling the stacks again after the rotation mechanism rotates the stacks by a certain angle; the unloading unit is used to receive the bundled stacks grasped by the grippers from the bundling unit and transport the stacks.

[0006] In the aforementioned stacking and bundling equipment, the workpiece is fed by the feeding unit, and its position is transferred by the transfer unit. Multiple workpieces are aligned in the stacking unit to form a stack, which is then bundled by the bundling unit. The unloading unit outputs the bundled stack, thus achieving automated stacking and bundling of workpieces with high efficiency. Furthermore, by moving the moving parts relative to the fixed parts, the distance between them becomes variable, allowing workpieces of different widths to form stacks of different sizes on the support platform. This ensures that multiple workpieces within each stack are aligned, making the stacking unit suitable for workpieces of varying widths and improving its adaptability. A rotating mechanism drives the grippers to rotate, causing the bundled stack to rotate and allowing the bundling unit to re-bundle the stack for even stronger bundling, thus enhancing the bundling strength. When the workpiece is a motherboard, this application can automate the stacking and bundling of motherboards with high efficiency, and it is applicable to motherboards of different widths, ensuring secure bundling of the motherboard stacks.

[0007] In some embodiments, the stacking and bundling equipment further includes an operating table, a fixing member including a fixed connecting part and a fixed stop part, and a moving part including a moving connecting part and a moving stop part. The fixed connecting part is fixedly disposed on the operating table, and the moving stop part is movably disposed on the operating table. The fixed stop part is connected to the end of the fixed connecting part away from the operating table, and the moving stop part is connected to the end of the moving connecting part away from the operating table. The fixed connecting part and the moving connecting part are located on opposite sides of the support platform and are used to clamp the stack to align multiple workpieces in the stack. The stacking unit further includes a first elastic member, which connects the support platform and the operating table and applies force to the support platform toward the fixed stop part and the moving stop part, so that the support platform, the fixed stop part, and the moving stop part press the stack.

[0008] In some embodiments, the stacking unit further includes a second elastic member and a first driving member. The first driving member is used to drive the movable connecting part to move to adjust the distance between the movable connecting part and the fixed connecting part. The second elastic member connects the first driving member and the movable connecting part and applies force to the movable connecting part towards the fixed connecting part, so that the fixed connecting part and the movable connecting part clamp the stack. Both the movable member and the fixed connecting part are provided with guide surfaces. The guide surfaces are provided on the side of the movable stop and the fixed connecting part facing away from the support platform. The guide surfaces are used to guide the workpiece to drive the movable connecting part away from the fixed connecting part and squeeze the second elastic member, so that the workpiece enters between the fixed connecting part and the movable connecting part.

[0009] In some embodiments, the strapping unit includes a strapping mechanism and a positioning mechanism. The strapping mechanism has a strapping position for placing a stack gripped by a gripper from the stacking unit. The strapping mechanism is used to strap the stack located at the strapping position. The positioning mechanism includes two positioning components, which are respectively located on two pairs of sides of the strapping position. The two positioning components can move relative to each other to clamp or release the stack.

[0010] In some embodiments, the positioning assembly includes a second driving member, an intermediate member, a slide rod, a third elastic member, and a pressing member. The second driving member, the intermediate member, the slide rod, and the pressing member are connected in sequence. The slide rod is slidably connected to the intermediate member so that the slide rod abuts against the second driving member. The third elastic member is sleeved on the slide rod and connects the intermediate member and the pressing member. The second driving member drives the intermediate member to move toward the pressing member so that the pressing member contacts the stack. The pressing member and the intermediate member squeeze the third elastic member, causing the slide rod to slide along the intermediate member until the slide rod abuts against the second driving member, thereby clamping the stack between the two pressing members.

[0011] In some embodiments, the gripper includes a third driving member, a pressure rod, a pressure head, a fourth elastic member, and two spaced-apart clamping plates. The third driving member is located on the rotating mechanism and drives the two clamping plates to move relative to each other to clamp or release the stack. The pressure rod is located between the two clamping plates, and the pressure head is connected to the end of the pressure rod away from the third driving member. The fourth elastic member is sleeved on the pressure rod and connects the pressure head and the third driving member. When the two clamping plates clamp the stack, the stack squeezes the pressure head, causing the fourth elastic member to apply force to the pressure head, so that the pressure head presses the stack tightly.

[0012] In some embodiments, the loading unit includes a first lifting platform, a transfer member, and a second lifting platform. The first lifting platform is used to carry multiple stacked pallets containing workpieces and can move the uppermost pallet to the loading position. The gripper is used to grab the workpieces in the pallet located at the loading position. The second lifting platform is used to carry multiple stacked empty pallets. The transfer member is used to grab the empty pallet located at the loading position and move it to the unloading position. The unloading position is located above the uppermost pallet on the second lifting platform.

[0013] In some embodiments, the transfer component includes a slide rail, a frame, and a plurality of suction cups. The suction cups are distributed on the frame and are used to adsorb empty trays. The slide rail extends from the upper material position to the lower material position, and the frame is slidably connected to the slide rail, so that the frame can move between the upper material position and the lower material position.

[0014] In some embodiments, the stacking and bundling equipment further includes an identification element, a marking element, and an adsorption element. The identification element is located on the translation mechanism and is used to identify the workpiece; the marking element is used to print a label; and the adsorption element is located on the rotation mechanism and is used to adsorb the label printed by the marking element and paste the label into the unloading unit for stacking.

[0015] In some embodiments, the translation mechanism includes a first translation member, a second translation member, and a third translation member. The second translation member is disposed on the first translation member. The first and second translation members drive the gripper to move along two perpendicular horizontal directions, respectively. The third translation member is disposed on the second translation member. The rotation mechanism is disposed on the third translation member. The third translation member is used to adjust the rotation mechanism and the gripper in the vertical direction. Attached Figure Description

[0081] The technical solution of this application will now be described with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments.

[0082] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0083] Furthermore, the terms "first," "second," and "third," etc., are used for descriptive purposes only and should not be interpreted as indicating or implying relative importance. The term "perpendicular" is used to describe an ideal state between two components. In actual production or use, two components may exist in a state that is approximately perpendicular. For example, combined with numerical descriptions, perpendicularity can refer to the angle between two straight lines within the range of 90° ± 10°, the dihedral angle between two planes within the range of 90° ± 10°, or the angle between a straight line and a plane within the range of 90° ± 10°. The two components described as "perpendicular" do not have to be absolutely straight lines or planes; they can be approximately straight lines or planes. From a macroscopic perspective, if the overall direction of extension is straight or plane, the component can be considered a "straight line" or "plane."

[0084] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0085] In the after-sales repair process of mobile phone motherboards, there is a section involving the packaging of scrapped motherboards. This requires bundling motherboards in certain quantities before packing them into boxes. Typically, workers manually stack multiple motherboards of the same size to align them, and then manually bundle the stacks together. This process is inefficient.

[0086] In view of this, it is necessary to provide a stacking and bundling device capable of stacking and bundling workpieces. The stacking and bundling device includes a feeding unit, a transfer unit, a stacking unit, a bundling unit, and an unloading unit. The loading unit provides workpieces; the transfer unit includes a translation mechanism, a rotation mechanism, and grippers connected in sequence. The grippers grip the workpieces, the rotation mechanism rotates the grippers, and the translation mechanism translates the grippers. The stacking unit includes a support platform, a fixing member, and a moving member. The support platform supports the workpieces gripped by the grippers from the loading unit, so that multiple workpieces form a stack. The fixing member and the moving member are respectively disposed on opposite sides of the support platform to limit the stack. The moving member can move relative to the fixing member to adjust the distance between the moving member and the fixing member. The binding unit receives the stacks gripped by the grippers from the stacking unit and binds the stacks. It also receives the stacks gripped by the grippers from the binding unit and binds the stacks again after the rotation mechanism rotates the stacks by a certain angle. The unloading unit receives the bound stacks gripped by the grippers from the binding unit and transports the stacks.

[0087] In the aforementioned stacking and bundling equipment, the workpiece is fed by the feeding unit, and its position is transferred by the transfer unit. Multiple workpieces are aligned in the stacking unit to form a stack, which is then bundled by the bundling unit. The unloading unit outputs the bundled stack, thus achieving automated stacking and bundling of workpieces with high efficiency. Furthermore, by moving the moving parts relative to the fixed parts, the distance between them becomes variable, allowing workpieces of different widths to form stacks of different sizes on the support platform. This aligns multiple workpieces within each stack, making the stacking unit suitable for workpieces of varying widths, thereby improving its adaptability. A rotating mechanism drives the grippers to rotate, causing the bundled stack to rotate and allowing the bundling unit to re-bundle the stack for even stronger bundling, thus enhancing the bundling strength. When the workpiece is a motherboard, this application can automate the stacking and bundling of motherboards with high efficiency, and it is also applicable to motherboards of different widths, ensuring secure bundling of the motherboard stacks.

[0088] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0089] Please see Figures 1-3 One embodiment of this application provides a stacking and bundling device 100, including a feeding unit 10, a transfer unit 20, a stacking unit 30, a bundling unit 40, and a unloading unit 50.

[0090] The feeding unit 10 is used to provide workpiece 210 ( Figure 5 (As shown). The workpiece 210 is conveyed to the designated position by the loading unit 10 so that the gripper 23 ( Figure 8 (As shown) Capture.

[0091] Please see Figure 4 and Figure 5 The stacking unit 30 includes a support platform 31, a fixing member 32, and a moving member 33. The support platform 31 is used to support the workpieces 210 gripped by the grippers 23 from the feeding unit 10, so that multiple workpieces 210 can form a stack. Multiple workpieces 210 stacked on the support platform 31 can form a stack. The fixing member 32 and the moving member 33 are respectively disposed on opposite sides of the support platform 31 to limit the stack. The fixing member 32 and the moving member 33 act on the front and rear sides of the stack, respectively, and can limit the front and rear sides of the stack, so that the front and rear sides of multiple workpieces 210 in the stack can be aligned. The moving member 33 can move relative to the fixing member 32 to adjust the distance between the moving member 33 and the fixing member 32, so as to facilitate the formation of stacks of different widths.

[0092] Please see Figure 6The bundling unit 40 is used to receive the stacks gripped by the gripper 23 from the stacking unit 30 and to bundle the stacks. By receiving and bundling the stacks through the bundling unit 40, the stacks can be bundled once. The bundling unit 40 is also used to receive the stacks gripped by the gripper 23 from the bundling unit 40, and to bundle the stacks again after the rotating mechanism 22 rotates the stacks at a certain angle. By receiving, rotating, and bundling the stacks after the first bundling, the stacks can be bundled again. Because the stacks are bundled once and then bundled again after rotation, the bundling positions on both sides are different, making the bundled stacks more secure and less prone to damage during transportation. As an example, the angle of the stack after the rotating mechanism 22 rotates the stacks at 90°, allowing the bundling unit 40 to perform a cross-bundle, ensuring that the stacks of multiple workpieces 210 are firmly bundled and that the multiple workpieces 210 are less likely to scatter.

[0093] Please see Figures 1-3 The unloading unit 50 is used to receive the bundled stacks gripped by the grippers 23 from the bundling unit 40 and to transport the stacks. The final bundled stacks are output through the unloading unit 50.

[0094] Please see Figure 7 and Figure 8 The transfer unit 20 includes a translation mechanism 21, a rotation mechanism 22, and a gripper 23 connected in sequence. The gripper 23 is used to grip the workpiece 210. Specifically, the gripper 23 has the function of gripping any material. The gripper 23 can grip the workpiece 210 of the feeding unit 10, can grip a stack of multiple workpieces 210 aligned on the support platform 31, can grip the bundled stack in the bundling unit 40, and can grip the stack after re-bundling in the bundling unit 40. The rotation mechanism 22 is used to rotate the gripper 23. It can adjust the angle of the gripper 23 so that the stack after one bundling in the bundling unit 40 gripped by the gripper 23 can be rotated at a certain angle, which is convenient for re-bundling the remaining positions of the stack. The translation mechanism 21 is used to translate the gripper 23. It can adjust the position of the gripper 23 so that the gripped object of the gripper 23 can be moved, which is convenient for transferring the workpiece 210 or the stack.

[0095] In the stacking and bundling equipment 100 of this application, the workpiece 210 is fed by the feeding unit 10, and the position of the workpiece 210 is transferred by the transfer unit 20, so that multiple workpieces 210 are aligned to form a stack in the stacking unit 30, the stack is bundled in the bundling unit 40, and the unloading unit 50 outputs the bundled stack, thus completing the automated stacking and bundling of the workpiece 210 with high work efficiency; in addition, by moving the moving part 33 relative to the fixed part 32, the distance between the moving part 33 and the fixed part 32 is increased. The stacking unit 30 is adjustable, allowing workpieces 210 of different widths to form stacks of different sizes on the support platform 31, and aligning multiple workpieces 210 in each stack so that the stacking unit 30 can be adapted to workpieces 210 of different widths, thereby improving the adaptability of the stacking unit 30; the rotating mechanism 22 drives the gripper 23 to rotate, causing the stack after being bundled by the bundling unit 40 to rotate, so that the bundling unit 40 can bundle the stack again, so that the stack is bundled more firmly, thereby improving the strength of the bundling unit 40 in bundling the stack.

[0096] As an exemplary example, workpiece 210 is a scrapped motherboard. At the packaging station for scrapped motherboards, motherboards of the same size need to be bundled in a certain quantity. Using the stacking and bundling equipment 100 of this application, the motherboards can be automatically stacked and bundled, achieving high work efficiency. It is also applicable to motherboards of different widths, forming stacks of varying widths, and securely bundling the motherboards within the stacks. In other embodiments, workpiece 210 can be stacked and packaged using the stacking and bundling equipment 100 as long as it has a plate-like structure.

[0097] Please see Figures 1-5In some embodiments, the stacking and bundling equipment 100 further includes an operating table 60. This facilitates the connection of the fixing member 32 and the moving member 33 via the operating table 60. The fixing member 32 includes a fixing connection portion 321 and a fixing stop portion 322. The fixing connection portion 321 is fixedly disposed on the operating table 60, and the fixing stop portion 322 is connected to the end of the fixing connection portion 321 away from the operating table 60. The moving member 33 includes a moving connection portion 331 and a moving stop portion 332. A guide rail 61 is provided on the operating table 60, and the lower end of the moving stop portion 332 can move along the guide rail 61, so that the moving stop portion 332 is movably disposed on the operating table 60. The moving stop portion 332 is connected to the end of the moving connection portion 331 away from the operating table 60. The fixed connecting part 321 is connected to the operating table 60 and the fixed stop part 322 at both ends, and the movable connecting part 331 is connected to the operating table 60 and the movable stop part 332 at both ends. The fixed connecting part 321 and the movable connecting part 331 are at the same height. When the fixed stop part 322 presses down on the stack, the movable stop part 332 also presses down on the stack. The fixed connecting part 321 and the movable connecting part 331 are located on opposite sides of the support platform 31 and are used to clamp the stack to align multiple workpieces 210 in the stack. The fixed connecting part 321 and the movable connecting part 331 are arranged facing each other. By moving the movable connecting part 331 relative to the fixed connecting part 321, the distance between the fixed connecting part 321 and the movable connecting part 331 can be adjusted to accommodate different widths of stacks formed by different workpieces 210. By moving the movable connecting part 331 closer to the fixed connecting part 321, the stack between the fixed connecting part 321 and the movable connecting part 331 can be clamped to align multiple workpieces 210 in the stack.

[0098] Please see Figure 4 and Figure 5 The stacking unit 30 also includes a first elastic element 34, which connects the support platform 31 and the operating table 60. The first elastic element 34 applies force to the support platform 31 towards the fixed stop 322 and the movable stop 332, so that the support platform 31, the fixed stop 322, and the movable stop 332 press the stack. When multiple workpieces 210 are stacked on the support platform 31, the support platform 31 contacts one side of the stack, the movable connection 331 and the fixed connection 321 clamp the two sides of the stack, the first elastic element 34 is elastically compressed by the stack, and has a tendency to elastically elongate, applying an upward force to the support member, so that the movable stop 332 and the fixed stop 322 simultaneously press the other side of the stack.

[0099] Therefore, the stacking unit 30 can adjust the distance between the support platform 31 and the fixed stop 322 through the elastic deformation of the first elastic member 34, which facilitates the formation of stacks of different thicknesses for multiple workpieces 210. In fact, mobile phone motherboards often have multiple models, and the thickness of different models of motherboards may vary. A stack is usually formed by stacking ten motherboards. Therefore, when such a stacking unit 30 is used to stack motherboards of various models, it can make each model of motherboard form a stack separately, which is suitable for stacking motherboards of various models.

[0100] In some embodiments, the stacking unit 30 further includes a movable rod 35 extending vertically. One end of the movable rod 35 is fixedly connected to the support platform 31, and the other end passes through the operating table 60. A first elastic member 34 is sleeved on the movable rod 35, ensuring that the first elastic member 34 extends or retracts along the extension direction of the movable rod 35, thus ensuring that the movement of the support platform 31 is always vertically upward or downward. This effectively prevents the support platform 31 from swaying during movement near or away from the fixed stop 322. As an exemplary example, the number of movable rods 35 and first elastic members 34 is the same, with one first elastic member 34 sleeved on each movable rod 35. Having two first elastic members 34 increases the stability of the support platform 31 during movement. Alternatively, the number of movable rods 35 and first elastic members 34 can be multiple depending on the actual application.

[0101] In some embodiments, the stacking unit 30 further includes a second elastic member 36 and a first driving member 37. The first driving member 37 is used to drive the movable connecting portion 331 to move, thereby adjusting the distance between the movable connecting portion 331 and the fixed connecting portion 321. The position of the movable connecting portion 331 can be adjusted by the first driving member 37 according to workpieces 210 of different widths, so that the distance between the movable connecting portion 331 and the fixed connecting portion 321 is adjustable.

[0102] The second elastic member 36 connects the first driving member 37 and the movable connecting part 331, and applies force to the movable connecting part 331 towards the fixed connecting part 321, causing the fixed connecting part 321 and the movable connecting part 331 to clamp the stack. By providing the second elastic member 36, the distance between the fixed connecting part 321 and the movable connecting part 331 is adjustable, allowing the workpiece 210 to enter between the fixed connecting part 321 and the movable connecting part 331.

[0103] Both the movable part 33 and the fixed connection part 321 are provided with guide surfaces 333. The guide surfaces 333 are inclined surfaces and are located on the side of the movable stop part 332 and the fixed connection part 321 facing away from the support platform 31. By providing guide surfaces 333, the distance between the movable stop part 332 and the fixed stop part 322 gradually decreases from the side away from the support platform 31 to the side close to the support platform 31, forming an entrance that is wider at the top and narrower at the bottom. This allows the guide surfaces 333 to guide the workpiece 210 to drive the movable connection part 331 away from the fixed connection part 321 and squeeze the second elastic member 36, so that the workpiece 210 enters between the fixed connection part 321 and the movable connection part 331.

[0104] In some embodiments, the first driving member 37 is a cylinder, which has a cylinder body and a piston rod. The piston rod is slidably disposed on the cylinder body, and the end of the piston rod away from the cylinder body is movable relative to the movable connecting portion 331. A second elastic member 36 is sleeved on the piston rod, with one end of the second elastic member 36 connected to the cylinder body and the other end of the second elastic member 36 connected to the movable connecting portion 331. As an exemplary example, the movable connecting portion 331 is provided with a groove, and the end of the piston rod away from the cylinder body is aligned with the groove. The piston rod moves along the cylinder body toward the fixed connecting portion 321 to drive the movable member 33 to move, so that the distance between the fixed member 32 and the movable member 33 can be adapted to the workpiece 210 of the corresponding size. In use, the workpiece 210 of the corresponding size is pushed open by the guide surface 333 to move the movable connecting part 331 away from the fixed connecting part 321 so that the workpiece 210 enters between the fixed connecting part 321 and the movable connecting part 331. At this time, the piston rod is inserted into the positioning groove, and the movable connecting part 331 and the cylinder press the second elastic member 36. The second elastic member 36 applies force to the movable connecting part 331 toward the fixed connecting part 321 so that the fixed connecting part 321 and the movable connecting part 331 clamp and stack.

[0105] In some embodiments, the stacking unit 30 includes two movable members 33 spaced apart, both of which are located on the same side of the stack, with one movable member 33 directly opposite the fixed member 32. The two movable members 33 enable better alignment of multiple workpieces 210 in the stack. Furthermore, multiple movable members 33 may be used depending on the actual application.

[0106] As an exemplary example, please refer to Figure 4 and Figure 5The stacking unit 30 includes a fixing member 32, a moving member 33, and two limiting members 38. The fixing member 32 and the moving member 33 are respectively disposed on opposite sides of the support platform 31 along a first direction. The fixing connection part 321 has a first limiting surface, and the moving connection part 331 has a second limiting surface. The first limiting surface and the second limiting surface face each other to limit the stack along the first direction, allowing the first and second limiting surfaces to clamp the two sides of the stack in the first direction. The two limiting members 38 are respectively disposed on two pairs of opposite sides of the support platform 31 along a second direction. The first and second directions are perpendicular. Each limiting member 38 has a third limiting surface. The two third limiting surfaces face each other to limit the stack along the second direction, allowing the two third limiting surfaces to limit the two sides of the stack in the second direction. Both the first and second directions are in the XY plane, with the first direction parallel to the Y-axis and the second direction parallel to the X-axis. Figure 1 and Figure 2 (As shown). Therefore, the stacking unit 30 can adapt to workpieces 210 of different widths by adjusting the distance between the fixing member 32 and the moving member 33, and can be used to form stacks of the same length but different widths. Mobile phone motherboards often have multiple models, and the dimensions of different models of motherboards are different, specifically in that the widths of different models of motherboards are different, while the lengths of different models of motherboards are usually the same. Therefore, when such a stacking unit 30 is used to stack multiple models of motherboards, each model of motherboard can be stacked separately, which is suitable for stacking various models of mobile phone motherboards.

[0107] As another exemplary example, the stacking unit 30 includes two fixing members 32 and two moving members 33. One fixing member 32 and one moving member 33 are respectively disposed on two pairs of sides of the support platform 31 along a first direction, and the other fixing member 32 and the other moving member 33 are respectively disposed on two pairs of sides of the support platform 31 along a second direction, with the first and second directions being perpendicular. Therefore, the stacking unit 30 can adapt to workpieces 210 of different widths by adjusting the spacing between the fixing member 32 and the moving member 33 in the first direction, and to workpieces 210 of different lengths by adjusting the spacing between the fixing member 32 and the moving member 33 in the second direction. It can stack workpieces 210 of different lengths, different widths, and both different lengths and widths.

[0108] Please see Figures 1-3 as well as Figure 6In some embodiments, the strapping unit 40 includes a strapping mechanism 41 and a positioning mechanism 42. The strapping mechanism 41 has a strapping position 411, which is located on the same plane as the operating table 60. The strapping position 411 is used to place the stack gripped by the gripper 23 from the stacking unit 30, and the strapping mechanism 41 is used to strap the stack located at the strapping position 411. The positioning mechanism 42 includes two positioning components 422, both of which are located on the operating table 60. The two positioning components 422 are respectively located on two pairs of sides of the strapping position 411, and the center of the two positioning components 422 is the strapping position 411 of the strapping mechanism 41. The two positioning components 422 can move relative to each other to clamp or release the stack. So that the two positioning components 422 clamp the stack, and the strapping mechanism 41 straps the center position of the stack, so that the stack can be securely strapped.

[0109] In some embodiments, two positioning components 422 are spaced apart along a second direction to clamp the stack grasped by the gripper 23 from the stacking unit 30 along the second direction. Since the moving member 33 and the fixing member 32 have clamped the stack along a first direction, the multiple workpieces 210 in the stack are aligned on both sides in the first direction. The two clamping plates 235 of the gripper 23 are also spaced apart along the first direction, so that the stack grasped by the gripper 23 from the stacking unit 30 is clamped by the two clamping plates 235 along the first direction, making the multiple workpieces 210 in the stack received by the binding position 411 aligned on both sides in the first direction. Therefore, by arranging the two positioning components 422 along the second direction, the two pressing members 4225 can clamp the stack along the second direction, making the multiple workpieces 210 in the stack aligned on both sides in the second direction. Through the cooperation of the stacking unit 30, the transfer unit 20, and the binding unit 40, the multiple workpieces 210 in the stack can be better aligned, making the multiple workpieces 210 in the stack completely aligned.

[0110] As an exemplary example, when the two positioning components 422 clamp the stack along the second direction, the binding mechanism 41 binds the stack clamped by the two positioning components 422 along the first direction, which is perpendicular to the second direction. In some embodiments, the positioning component 422 includes a second driving member 4221, an intermediate member 4222, a slide bar 4223, a third elastic member 4224, and a pressing member 4225. The second driving member 4221, the intermediate member 4222, the slide bar 4223, and the pressing member 4225 are connected in sequence. The second driving member 4221 can drive the pressing member 4225 to move through the intermediate member 4222 and the slide bar 4223, so that the pressing members 4225 of the two positioning components 422 are relatively close or relatively far apart, thereby clamping or releasing the stack.

[0111] The slide rod 4223 is slidably connected to the intermediate member 4222. The intermediate member 4222 is provided with a through hole. The slide rod 4223 passes through the through hole. One end of the slide rod 4223 is connected to the pressure member 4225. The slide rod 4223 moves in the through hole, causing the other end of the slide rod 4223 to move closer to or away from the second driving member 4221. The third elastic member 4224 is sleeved on the slide rod 4223 and connects the intermediate member 4222 and the pressure member 4225. The second driving member 4221 drives the intermediate member 4222 to move towards the pressing member 4225, causing the pressing member 4225 to contact the stack. At this time, the two pressing members 4225 clamp the stack, and the interaction force between the pressing members 4225 and the stack causes the pressing members 4225 and the intermediate member 4222 to compress the third elastic member 4224. The third elastic member 4224 is elastically compressed, and then the slide rod 4223 slides along the intermediate member 4222. The slide rod 4223 moves along the through hole until its other end abuts against the second driving member 4221. At this time, the two pressing members 4225 can stably clamp the stack. The third elastic member 4224 plays the role of connecting the pressing member 4225 and the intermediate member 4222 in the positioning assembly 422, and also plays a buffering role in the process of the two positioning assemblies 4222 clamping the stack, avoiding rigid contact between the pressing member 4225 and the stack.

[0112] Please see Figure 7 In some embodiments, the gripper 23 includes a third drive member 231, a pressure bar 233, a pressure head 234, a fourth elastic member 232, and two spaced-apart clamping plates 235. The two clamping plates 235 are arranged opposite each other to clamp the stack. The third drive member 231 drives the two clamping plates 235 to move relative to each other to clamp or release the stack. The third drive member 231 is provided on the rotating mechanism 22 so that the rotating mechanism 22 drives the stack clamped between the two clamping plates 235.

[0113] A pressure bar 233 is positioned between two clamping plates 235. A connecting frame 236 is positioned between the two clamping plates 235 and connected to a third driving member 231. The pressure bar 233 passes through the connecting frame 236 and can move up and down relative to the connecting frame 236, allowing the upper end of the pressure bar 233 to move closer to or further away from the driving member. A pressure head 234 is connected to the end of the pressure bar 233 away from the third driving member 231. A fourth elastic member 232 is fitted onto the pressure bar 233 and connects the pressure head 234 to the third driving member 231. When the two clamping plates 235 clamp the stack, the upper surface of the stack presses against the pressure head 234. The pressure head 234 and the pressure bar 233 move upward relative to the connecting frame 236, causing the fourth elastic member 232 to be elastically compressed by the pressure head 234 and the connecting frame 236. The fourth elastic member 232 has a tendency to elastically elongate and exerts force on the pressure head 234, causing the pressure head 234 to press the stack tightly.

[0114] Please see 1- Figure 3 as well as Figure 8In some embodiments, the loading unit 10 includes a first lifting platform 11, a transfer member 12, and a second lifting platform 13. The first lifting platform 11 is used to carry multiple pallets 200 stacked with workpieces 210, and can move the uppermost pallet 200 to the loading position 111. As an exemplary example, the first lifting platform 11 rises and falls via a lifting rail to deliver the multiple stacked pallets 200 one by one to the loading position 111.

[0115] The gripper 23 is used to grasp the workpiece 210 in the pallet 200 located at the loading position 111. The second lifting platform 13 is used to carry multiple stacked empty pallets 200, and the transfer member 12 is used to grasp the empty pallet 200 located at the loading position 111 and move it to the unloading position 131, which is located above the uppermost pallet 200 on the second lifting platform 13. As an exemplary example, the second lifting platform 13 rises and falls via a lifting rail to receive the empty pallets 200 moved to the unloading position 131 one by one.

[0116] In some embodiments, the first elastic element 34, the second elastic element 36, the third elastic element 4224, and the fourth elastic element 232 are all springs.

[0117] As an exemplary example, both the first lifting platform 11 and the second lifting platform 13 are located below the operating table 60. The operating table 60 has a loading opening and a unloading opening spaced apart. The loading position 111 is located directly below the loading opening, aligning the loading position 111 with the loading opening. The unloading position is located directly below the unloading opening, aligning the unloading position with the unloading opening. A transfer member 12 is located on the operating table 60 and can move between the loading opening and the unloading opening to transfer the pallet 200 from the loading position 111 to the unloading position 131.

[0118] In some embodiments, the transfer member 12 includes a slide rail 121, a frame 122, and a plurality of suction cups 123. The plurality of suction cups 123 are distributed on the frame 122 and are used to absorb empty trays 200. The slide rail 121 is disposed on the operating table 60 and extends from the loading position 111 to the unloading position 131. The frame 122 is slidably connected to the slide rail 121. The frame 122 can move between the loading position 111 and the unloading position 131 by sliding along the slide rail 121, so as to transfer the empty trays 200 from the loading position 111 to the unloading position 131. The empty trays 200 can be unloaded by the second lifting platform 13.

[0119] Please see Figures 1-3 In some embodiments, the stacking and bundling equipment 100 further includes an identification element 70, a marking element 80, and an adsorption element 90. Figure 7(As shown). Identifier 70 is located on translation mechanism 21 and is used to identify workpiece 210. Marking component 80 is located on operating table 60 and is used to print labels. Adsorption component 90 is located on rotation mechanism 22 and is used to adsorb the labels printed by marking component 80 and attach the labels to the unloading unit 50 for stacking. As an example, identifier 70 identifies the QR code on the mobile phone motherboard. The label printed by marking component 80 is a barcode or QR code.

[0120] Please see Figure 1 In some embodiments, the unloading unit 50 includes a conveyor belt and a clamping member 51 disposed at one end of the conveyor belt. The clamping member 51 is used to clamp the bundled stack grasped by the gripper 23 from the bundling unit 40, so that the adsorbent 90 with the label attached is moved to the corresponding area of ​​the clamping member 51 by the translation mechanism 21 to attach the label to the stack clamped by the clamping member 51. After the stack is labeled, the clamping member 51 releases the stack with the label attached, and the stack falls onto the conveyor belt, which transports the stack with the label attached. As an exemplary example, the clamping member 51 includes a cylinder and two clamping plates, the cylinder driving the two clamping plates to move closer or further apart to clamp the stack.

[0121] Please see Figure 8 In some embodiments, the translation mechanism 21 includes a first translation member 211, which drives the gripper 23 to move horizontally. The translation mechanism 21 also includes a second translation member 212, which drives the gripper 23 to move horizontally. The second translation member 212 is disposed on the first translation member 211, and the first and second translation members 211 and 212 respectively drive the gripper 23 to move in two perpendicular horizontal directions. The translation mechanism 21 also includes a third translation member 213, which drives the rotation mechanism 22 to move vertically, thereby causing the gripper 23 connected to the rotation mechanism 22 to move vertically. The XY plane is a horizontal plane, the horizontal direction is any direction within the horizontal plane, and the vertical direction is parallel to the Z-axis, i.e., the vertical direction is perpendicular to the horizontal direction. Figure 1 and Figure 2 (As shown). The third translation member 213 is disposed on the second translation member 212, and the rotation mechanism 22 is disposed on the third translation member 213. The third translation member 213 is used to adjust the rotation mechanism 22 and the gripper 23 in the vertical direction. The gripper 23 is driven to move by the translation mechanism 21, thereby transferring the position of the workpiece 210 or stacked materials held by the gripper 23.

[0122] In some embodiments, the rotating mechanism 22 includes a rotating shaft and an extension plate. The rotating shaft connects a motor to the extension plate, enabling the motor to drive the extension plate to rotate. The motor is connected to a third translation member 213, which adjusts the position of the gripper 23 in the vertical direction by adjusting the position of the motor in the vertical direction. The extension plate extends laterally, and the rotating shaft is connected to the middle region of the extension plate. The gripper 23 is connected to one end of the extension plate, facilitating the insertion of the gripper 23 into the strapping unit 40, which facilitates moving the stack to the strapping position 411 to complete the strapping. The adsorption member 90 is connected to the other end of the extension plate. The adsorption member 90 and the gripper 23 are connected by an extension plate, ensuring that the gripper 23 and the adsorption member 90 always maintain the same angle, so that when the adsorption member 90 affixes the label to the stack, the angle of the label on the stack is consistent.

[0123] Please see Figures 1-8 In some embodiments, the stacking and bundling equipment 100 operates as follows:

[0124] Multiple pallets 200 containing workpieces 210 are stacked on the first lifting platform 11, and the first lifting platform 11 moves the pallets 200 to the loading position 111.

[0125] The identification component 70 identifies the workpiece 210. Based on the identification result of the identification component 70, the marking component 80 marks the label. The gripper 23 picks up the workpiece 210 from the loading position 111. The gripper 23 is moved by the translation mechanism 21 and the workpiece 210 picked up by the gripper 23 is placed on the support platform 31. The steps of the gripper 23 picking up the workpiece 210 are repeated so that multiple workpieces 210 are stacked on the support platform 31.

[0126] Move the moving part 33 away from the fixed part 32, so that the gripper 23 can grab the stack from the support platform 31. Move the gripper 23 through the translation mechanism 21, and place the stack grabbed by the gripper 23 into the binding position 411. The two positioning components 422 clamp the stack in the binding position 411, and the binding mechanism 41 binds the stack.

[0127] The two positioning components 422 loosen the bundled stack, the gripper 23 grasps the stack, the rotating mechanism 22 rotates the stack, the translation mechanism 21 moves the gripper 23, and the rotated stack is placed in the bundling position 411. The two positioning components 422 clamp the stack in the bundling position 411, and the bundling mechanism 41 bundles the stack again to form a cross bundling, so that the stack is firmly bundled.

[0128] The two positioning components 422 are loosened and the stack is re-tied. The stack is then tied up. The clamping mechanism 21 moves the gripper 23 to place the tied stack into the unloading unit 50.

[0129] The translation mechanism 21 moves the adsorption component 90 to the marking component 80 to adsorb the label. The translation mechanism 21 then moves the adsorption component 90 with the label to the unloading unit 50, where the label is affixed to the bundled stack. When the pallet 200 at the loading position 111 is empty, the transfer component 12 transfers the empty pallet 200 to the unloading position 131. The second lifting platform 13 receives the empty pallets 200 one by one, stacking the empty pallets 200 on the second lifting platform 13.

[0130] The first lifting platform 11 moves the next pallet 200 to the loading position 111. The identification component 70 identifies the workpiece 210 again. Based on the identification result of the identification component 70, the marking component 80 marks the label again. The gripper 23 grabs another workpiece 210 from the loading position 111 to the carrying platform 31. The above steps are repeated to pack another stack.

[0131] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
