Description

Technical Field

[0001] This utility model relates to the field of automated equipment, and in particular to a material feeding assembly line device. Background Technology

[0002] With the continuous improvement of industrial automation, automated production lines have been widely used in many industries such as electronics, light industry, food, and pharmaceuticals. In the final stage of product manufacturing, it is usually necessary to sort, count, and stack the finished products in an orderly manner in trays to facilitate subsequent transportation, warehousing, and shipping.

[0003] Currently, there are various ways to implement the material unloading and palletizing process on the production line. The traditional method mainly relies on manual stacking, which is labor-intensive, inefficient, and prone to errors due to fatigue. While existing automated unloading equipment has reduced the burden on manpower to some extent, it still has many limitations, such as low space utilization. Many devices adopt a horizontal layout, with empty pallet bins, receiving stations, and full pallet bins arranged horizontally in sequence, resulting in a large footprint and difficulty in deployment in factories with limited space. The automation continuity is also poor. Some devices cannot automatically replenish empty pallets or automatically unload and temporarily store full pallets. When a single pallet is full, the machine must be stopped and the empty pallet must be replaced manually and the full pallet removed, interrupting the production process and affecting the overall production line efficiency. Utility Model Content

[0004] In view of the above, this utility model provides a material feeding production line equipment with a compact layout, high degree of automation, reliable operation, and the ability to achieve continuous material feeding operation.

[0005] This utility model specifically adopts the following technical solution: a material unloading assembly line equipment, including a product conveyor line, a material conveying robot mounted above the product conveyor line, and a material unloading and storage mechanism located in the unloading direction of the material conveying robot; wherein, the material unloading and storage mechanism includes an empty pallet stacking bin mounted above the machine platform, a receiving and lifting mechanism movably located below the empty pallet stacking bin, and a full pallet receiving mechanism movably located inside the machine platform and located below the receiving and lifting mechanism; the empty pallet stacking bin includes a base plate with a through-type operation window in the middle, and three sets of support components movably located on opposite sides of the operation window, the three sets of support components being positioned on the base plate... The operating window extends and retracts to support stacked empty trays. The receiving lifting mechanism includes a first lifting drive mechanism vertically installed inside the machine and a receiving component installed on the first lifting drive mechanism. The receiving component rises under the drive of the first lifting drive mechanism to receive a single tray and then falls back to the operating plane. The full tray receiving mechanism includes a second lifting drive mechanism installed on one side of the first lifting drive mechanism and a top plate installed on the second lifting drive mechanism. The second lifting drive mechanism drives the top plate to rise to receive a tray with product materials installed on the receiving component and then falls back to avoid it. Multiple trays can be received in a cycle.

[0006] As a further improved technical solution, the three sets of support components are an upper support plate, a lifting support plate, and a lower support plate. The upper support plate is mounted on the upper surface of the base plate via a first translation cylinder, which drives it to move on both sides of the operation window and insert into the bottom of the second-to-last tray in the direction of the operation window. The lifting support plate is mounted on the upper surface of the base plate via a second translation cylinder, which is also equipped with a lifting cylinder. The lifting support plate has an L-shaped structure, with its long side located on the lifting cylinder. The second translation cylinder and the lifting cylinder drive the horizontal movement and vertical lifting of the lifting support plate, respectively. The lower support plate is mounted on the bottom of the base plate via a third translation cylinder, which drives it to move on both sides of the operation window and move to the bottom of the lowest tray in the direction of the operation window.

[0007] As a further improved technical solution, the receiving assembly includes a receiving plate and a movable support plate. The receiving plate has a receiving port, and the movable support plate is movably mounted on the receiving plate by a fourth translation cylinder and is located on opposite sides of the receiving port to support the material tray to be received.

[0008] As a further improved technical solution, a guide block is provided in each of the end corners of the receiving port, and is mounted on the receiving plate by a guide fixing block. The guide block has a trapezoidal structure, with the hypotenuse of the guide block facing upward and towards the inside of the receiving port. An arc chamfer is provided at the connection between the hypotenuse of the guide block and the adjacent straight side.

[0009] As a further improved technical solution, the first lifting drive mechanism includes a first lead screw, a first motor, a first guide rail, and a receiving connection plate. The first lead screw and the first motor are vertically mounted inside the machine base via a mounting plate. The first guide rail is parallel to both sides of the first lead screw. The receiving connection plate is mounted on the first lead screw and is slidably connected to the first guide rail. The receiving connection plate has first supporting reinforcing ribs on both sides, and the first supporting reinforcing ribs are connected to the bottom of the receiving plate.

[0010] As a further improved technical solution, the second lifting drive mechanism includes a second lead screw, a second motor, a second guide rail, and a lifting connecting plate. The second lead screw and the second motor are vertically mounted inside the machine base via fixed side plates. The second guide rail is parallel to both sides of the second lead screw. The lifting connecting plate is mounted on the second lead screw and is slidably connected to the second guide rail. The lifting connecting plate has second supporting reinforcing ribs on both sides, and the second supporting reinforcing ribs are connected to the bottom of the top plate.

[0011] As a further improved technical solution, the size of the top plate is smaller than the size of the material tray.

[0012] As a further improved technical solution, corner baffles are provided at the four corners of the operation window on the base plate.

[0013] As a further improved technical solution, the material handling robot includes an X-axis moving module, a first Y-axis moving module, a Z-axis moving module, a guide bracket, a second Y-axis moving module, and a product picking component. The first Y-axis moving module is mounted on the machine platform and located on one side of the unloading and storage mechanism. The X-axis moving module is mounted on the first Y-axis moving module, the Z-axis moving module is mounted on the X-axis moving module, the guide bracket is mounted on the Z-axis moving module and is parallel to the first Y-axis moving module, and the product picking component is mounted on the second Y-axis moving module.

[0014] As a further improved technical solution, the product conveyor line is a belt conveyor line or a roller conveyor line, and the conveying direction is set perpendicular to the unloading direction.

[0015] The material feeding assembly line equipment of this utility model has the following beneficial effects: Through the original design of the three-layer vertical space architecture, the empty pallet stacking bin, the material receiving and lifting mechanism and the full pallet receiving mechanism are integrated into one unit in the vertical direction. This compact layout of "upper storage, middle receiving and lower storage" greatly reduces the horizontal footprint of the equipment and improves space utilization.

[0016] This solution integrates the entire process of automatic empty tray feeding, single tray connection, product stacking, and automatic transfer and temporary storage of full trays. The empty tray stacking hopper can automatically and reliably release individual empty trays, the receiving lifting mechanism accurately receives and positions the empty trays on the working plane, and the full tray receiving mechanism can silently remove and buffer full trays. The entire process requires no manual intervention, ensuring continuous and efficient operation of the production line and significantly improving production efficiency. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set up" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through the specific circumstances.

[0023] Reference Figure 1 This embodiment of a material unloading production line includes a product conveyor line 1, a material handling robot 2 mounted above the product conveyor line 1, and a material unloading and storage mechanism located in the unloading direction of the material handling robot 2. The material unloading and storage mechanism can achieve smooth and continuous operation functions in a vertical space, including empty tray stacking and temporary storage, receiving single trays, and lowering full trays for temporary storage. Specifically, the material unloading and storage mechanism includes an empty tray stacking bin 3 mounted above the machine base 6, a receiving lifting mechanism 4 movably located below the empty tray stacking bin 3, and a full tray receiving mechanism 5 movably located inside the machine base 6 and below the receiving lifting mechanism 4.

[0024] Further reference Figures 2-3 The empty pallet stacking hopper 3 includes a base plate 31 with a through-type operating window in the middle, and three sets of support components movably located on opposite sides of the operating window. The three sets of support components extend and retract on the base plate 31 toward the operating window to support the stacked empty pallets 100. Specifically, the base plate 31 is supported on the machine base 6 by pillars 311. Corner baffles 32 are provided at the four corners of the operating window of the base plate 31 to facilitate guiding and stabilizing the stacked pallets. The three sets of support components include an upper support plate 33, a lifting support plate 34, and a lower support plate 35. The upper support plate 33 is located on the upper surface of the base plate 31 by a first translation cylinder 36, which drives it to move on both sides of the operating window and move toward the operating window to insert into the bottom of the second to last pallet, thus lifting all empty pallets 100 except the bottom one. The lifting pallet 34 is mounted on the upper surface of the base plate 31 via the second translation cylinder 37. The second translation cylinder 37 is also equipped with a lifting cylinder 38. The lifting pallet 34 has an L-shaped structure, with its long side located on the piston end of the lifting cylinder 38. The second translation cylinder 37 and the lifting cylinder 38 drive the horizontal movement and vertical lifting of the lifting pallet 34, respectively. The lower support plate 35 is mounted on the bottom of the base plate 31 via the third translation cylinder 39. Driven by the third cylinder 39, the plate moves to the bottom of the lowest material tray in the direction of the operation window, supporting all the empty material trays stacked above. Preferably, when the lifting cylinder 38 raises the lifting pallet 34 to its highest limit, the horizontal short side of the lifting pallet 34 is at the same height as the upper pallet 33. At this time, it functions the same as the upper pallet 33. Driven by the second translation cylinder 37, it moves inward and inserts into the bottom of the second-to-last tray. Together with the upper pallet 33, it holds up all empty trays except the bottom one. After the bottom tray descends and is taken away, the upper pallet 33 retracts, the lower support plate 35 extends, and the lifting cylinder 38 drives the lifting pallet 34 to smoothly land on the lower support plate 35 with the upper tray. Then, the second translation cylinder 37 drives it to retract and detach from the tray, and the lifting cylinder 38 drives it to rise and reset, waiting for the next operation.

[0025] When the operator places an empty pallet 100 into the empty pallet stacking hopper 3, the lower support plate 35 extends to support all the pallets 100 above. When unloading begins, the receiving lifting mechanism 4 rises to connect with a single pallet 100. The upper support plate 33 and the lifting support plate 34 extend and hold the bottom of the second-to-last pallet. The lower support plate 35 retracts, and the bottom pallet falls onto the receiving lifting mechanism 4, which descends with it, leaving the movement area of ​​the lower support plate 35. The lower support plate 35 then extends again, the upper support plate 33 retracts, and the lifting support plate 34, carrying all the pallets, descends onto the lower support plate 35 and resets, awaiting the next release of pallets 100. The dynamic coordination of the three sets of support components, through precise timing, ensures that multiple mechanisms always support the pallet stack, ensuring that the pallets stacked above remain stable when the bottom single pallet is released, completely avoiding the risks of jamming, scattering, or falling.

[0026] The receiving and lifting mechanism 4 includes a first lifting drive mechanism vertically installed inside the machine base 6 and a receiving component installed on the first lifting drive mechanism. The receiving component rises under the drive of the first lifting drive mechanism to receive the single-pane material tray 100 and then falls back to the operating plane, which is the working position on the surface of the machine base 6 waiting for the material handling robot 2 to release the material. The receiving component includes a receiving plate 41 and a movable support plate 42. The receiving plate 41 has a receiving port. The movable support plate 42 is movably installed on the receiving plate 41 by a fourth translation cylinder 43 at the bottom of the receiving plate 41 and is located on opposite sides of the receiving port to support the material tray 100 to be received. A guide block 44 is provided at each of the four corners of the receiving port, and is mounted on the receiving plate 41 by a guide fixing block. The guide block 44 has a trapezoidal structure, with its hypotenuse facing upwards and towards the inside of the receiving port. The connection between the hypotenuse and the adjacent straight edge of the guide block 44 is provided with an arc chamfer. The setting of the guide block 44 allows the receiving plate 41 to smoothly guide the material tray into the receiving port, ensuring that the position of each material tray 100 is consistent. On both sides of the receiving port where there is no movable support plate 42, the guide block 44 is directly provided on the receiving plate 41, which can further guide and position the connected material trays 100.

[0027] The first lifting drive mechanism includes a first lead screw 45, a first motor, a first guide rail 46, and a receiving connection plate 47. The first lead screw 45 and the first motor are vertically fixed inside the machine base 6 via a mounting plate 48. One end of the first lead screw 45 is connected to the output end of the first motor via a coupling, synchronous pulley, synchronous belt, or other common mechanical connection structure, and is driven to rotate by the first motor. The first guide rail 46 is arranged parallel to both sides of the first lead screw 45 on the mounting plate 48. The receiving connection plate 47 is located on the nut of the first lead screw 45 and is slidably connected to the first guide rail 46 via a matching slider. The receiving connection plate 47 has first supporting reinforcing ribs 49 on both sides, and the first supporting reinforcing ribs 49 are fixedly connected to the bottom of the receiving plate 41 so as to drive the receiving plate 41 to lift.

[0028] The full-receiving mechanism 5 includes a second lifting drive mechanism located on one side of the first lifting drive mechanism and a top plate 51 located on the second lifting drive mechanism. The second lifting drive mechanism drives the top plate 51 to rise and connect to the material tray 100 loaded with product materials on the receiving assembly, and then lowers to avoid it. It can cyclically connect multiple material trays 100. The size of the top plate 51 is smaller than the size of the material tray 100 so that it can rise to avoid the movable support plates 42 on both sides of the receiving plate 41 and support the middle of the product for stable unloading. The second lifting drive mechanism includes a second lead screw 52, ​​a second motor 53, a second guide rail 54, and a lifting connecting plate 55. The second lead screw 52 and the second motor 53 are vertically fixed inside the machine base 6 via a fixed side plate 56. One end of the second lead screw 52 is connected to the output end of the second motor 53 via a coupling, synchronous pulley, synchronous belt, or other common mechanical connection structure, and is driven to rotate by the second motor 53. The second guide rail 54 is arranged parallel to both sides of the second lead screw 52 on the fixed side plate 56. The lifting connecting plate 55 is located on the nut of the second lead screw 52 and is slidably connected to the second guide rail 54 via a matching slider. The lifting connecting plate 55 has second supporting reinforcing ribs 57 on both sides, and the second supporting reinforcing ribs 57 are fixedly connected to the bottom of the top plate 51 so as to drive the top plate 51 to lift and connect to the material tray 100 containing the product on the receiving plate 41. In this embodiment, the first motor and the second motor 53 can be stepper motors or servo motors.

[0029] Reference Figure 4The material handling robot 2 includes an X-axis moving module 21, a first Y-axis moving module 22, a Z-axis moving module 23, a guide bracket 24, a second Y-axis moving module 25, and a product picking component 26. The first Y-axis moving module 22 is mounted on the machine base 6 via a support frame 27 and is located on one side of the unloading and storage mechanism. A Y-axis guide rail 28 is also mounted on the side parallel to the first Y-axis moving module 22 via the support frame 27. The X-axis moving module 21 is mounted on the first Y-axis moving module 22. Furthermore, the X-axis moving module 21 is spanned across the first Y-axis moving module 22 and the Y-axis guide rail 28 via a crossbeam, and translates along the Y-axis guide rail 28 under the drive of the first Y-axis moving module 22. The Z-axis moving module 23 is mounted on the X-axis moving module 21, the guide bracket 24 is mounted on the Z-axis moving module 23 and is parallel to the first Y-axis moving module 22, and the product picking component 26 is mounted on the second Y-axis moving module 25. Product pickup component 26 can be an existing vacuum nozzle or electric gripper, selected appropriately according to the specific product, and is used to pick up products on product conveyor line 1. Product pickup component 26 is driven by X-axis moving module 21, Y-axis moving module (first Y-axis moving module 22 and second Y-axis moving module 25), and Z-axis moving module 23 to perform three-axis motion: horizontal (lateral), horizontal (longitudinal), and vertical (lifting). X-axis moving module 21, Y-axis moving module, and Z-axis moving module 23 include, but are not limited to, linear motors, servo motors, and lead screws—various electromechanical devices capable of achieving horizontal X-axis, Y-axis, and vertical Z-axis motion, including power devices, transmission devices, and control devices. The second Y-axis moving module 25 allows product pickup component 26 to extend its feeding distance, greatly expanding its operating range and enabling it to cover a larger product conveyor line area and receiving area, adapting to different production line layouts and product specifications, thus having broad application prospects. Driven by the X-axis moving module 21, the Y-axis moving module (first Y-axis moving module 22 and second Y-axis moving module 25), and the Z-axis moving module 23, the product picking component 26 picks up the products one by one from the product conveyor line 1 and transfers them to the tray 100 on the receiving plate 41.

[0030] Product conveyor line 1 can be an existing belt conveyor or roller conveyor, and the conveying direction of product conveyor line 1 is set perpendicular to the unloading direction.
