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] In automated production lines of industries such as electronics, semiconductors, and small components, trays are general-purpose fixtures for carrying and transferring precision parts, semiconductor chips, and microelectronic components. Automated loading mechanisms are one of the key pieces of equipment for achieving efficient and continuous production. Currently, common tray loading mechanisms typically adopt a horizontal layout, arranging the full tray bin, loading station, and empty tray return area sequentially in a horizontal direction. This layout has certain limitations. For example, a horizontal, linear layout requires a long conveyor line, resulting in a large overall footprint; the empty tray return path often also occupies horizontal space, leading to low space utilization; and the loading and unloading points for full and empty trays are usually located on different sides of the equipment, requiring operators to work around the equipment, increasing operational complexity and walking distance, and hindering efficient management. Utility Model Content

[0003] In view of the above, this utility model provides a feeding assembly line equipment with a more compact layout, high space utilization, automatic empty tray recycling, and easy operation, so as to solve the outstanding problems existing in the prior art.

The module includes a hopper base plate, a hopper tray, and a hopper tray driving component. A through-hole tray window is opened in the center of the hopper base plate, and baffles are provided around the tray window. The hopper tray supports the stacked full trays above the tray window. A single-tray conveying module is mounted on the machine base and located below the hopper tray. It includes a first synchronous conveying mechanism, a U-shaped moving tray, and a lifting mechanism. The lifting mechanism is located below the tray window, rises through the U-shaped moving tray to support the single full tray, and descends to bring the full tray onto the U-shaped moving tray. The first synchronous conveying mechanism drives the U-shaped moving tray to convey the full tray. A waiting-to-feed module is also included. Located on the same conveying line as the single-disc conveying module, the system includes opposing support side plates and side positioning trays on the support side plates. A full tray is conveyed between the support side plates by the U-shaped moving tray and supported and fixed by the side positioning trays, awaiting material removal. A loading robot is mounted above the waiting-to-load module to transfer products from full trays. An empty tray lifting module includes a vertical lifting module and a support rod on the vertical lifting module. The vertical lifting module is located at one end of the support side plate and extends into the machine, driving the support rod to move up and down below the waiting-to-load module to connect trays that have been emptied. An empty tray conveying module is located inside the machine and includes a second synchronous conveying mechanism extending below the support rod and interleaved with it, for receiving trays on the support rod.

[0005] As a further improved technical solution, the hopper pallet driving component includes a first driving cylinder, the fixed end of the first driving cylinder is disposed on the bottom plate of the hopper, the hopper pallet is disposed opposite to the two sides of the tray window, and is connected to the piston end of the first driving cylinder. The hopper pallet is provided with a plurality of protrusion structures on the side of the hopper pallet near the tray window, and the hopper pallet is driven by the first driving cylinder to extend towards the tray window to support the tray.

[0006] As a further improved technical solution, the first synchronous transmission mechanism includes a first motor, a first drive shaft, a first drive synchronous pulley, a first driven synchronous pulley, and a first synchronous belt.

[0007] As a further improved technical solution, the lifting mechanism includes a top plate, a second motor, and a first lead screw. The second motor is mounted inside the machine base, the first lead screw is located at the output end of the second motor, and the top plate is mounted on the first lead screw. The second motor drives the top plate to rise and fall.

[0008] As a further improved technical solution, the side positioning plate is moved horizontally on the support side plate by a second drive cylinder.

[0009] As a further improved technical solution, an L-shaped positioning baffle is provided at the end of the support side plate near the vertical lifting module.

[0010] As a further improved technical solution, the loading robot includes an X-axis moving module, a Y-axis moving module, a Z-axis moving module, and a product picking component.

[0014] The feeding assembly line equipment of this utility model has the following beneficial effects: This design greatly saves space and effectively optimizes space utilization. It adopts a three-layer vertical layout of "top-middle-bottom", placing the full-load stacking module on top of the equipment, the single-disc conveying and loading operation in the middle, and the empty disk lifting and recycling system integrated inside the lower part of the equipment. This design integrates the traditional horizontally laid-out functional units into a compact vertical space, greatly reducing the floor area of ​​the equipment. The empty disk recycling process does not occupy any additional horizontal operating space, solving the fundamental defect of the traditional layout having a large floor area.

[0015] It achieves full-process automation and seamless integration with production. Through the coordinated operation of the full-material stacking module, single-disc conveying module, empty-disc lifting module and empty-disc conveying module, it realizes the closed-loop automation of the entire process from automatic supply of full-material trays, precise single-disc conveying, automatic product picking, to automatic descent and transfer of empty trays out of the equipment. It avoids production interruptions caused by manual tray replacement, ensures the continuous and efficient operation of the production line, and significantly improves the overall production efficiency.

[0016] It also features excellent human-machine interaction and ease of operation, adopting a user-friendly "same-side operation" design. The loading of the full material tray and the recycling outlet of the empty tray are both located on the same side of the equipment. This allows operators to complete all material loading and unloading management tasks at only one workstation, greatly simplifying the operation process, reducing personnel movement, and lowering labor intensity. It is very much in line with the principles of ergonomics and facilitates centralized management and monitoring. Attached Figure Description

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 Figures 1-2 This embodiment of a feeding assembly line includes a machine base 1, a full-load stacking module 2, a single-plate conveying module 3, a waiting-for-feeding module 4, a feeding robot 5, an empty-plate lifting module 6, and an empty-plate conveying module 7. The full-load stacking module 2 can stack multiple trays 100 filled with products. During feeding, each tray 100 descends to the single-plate conveying module 3 and is then conveyed to the waiting-for-feeding module 4 for fixation. The feeding robot 5 then removes the products from the trays 100. After all products have been removed, the empty-plate lifting module 6 lowers the empty trays from below the waiting-for-feeding module 4 into the machine base 1. The empty-plate conveying module 7 then automatically sends the empty trays out of the equipment. This layout saves space, automatically recovers empty trays, does not occupy the upper operating space, and the upper and lower trays 100 are all on one side of the equipment, making it easier for operators to use and increasing efficiency.

[0024] The following is a detailed explanation of each module.

[0025] Reference Figure 3The full-material stacking module 2 is mounted on the machine base 1 and includes a hopper base plate 21, a hopper support plate 22 and a hopper support plate driving component. A through tray window 211 is opened in the middle of the hopper base plate 21, and baffles 23 are provided around the tray window 211 to guide and block the stacked trays 100. The hopper support plate 22 supports the stacked full trays 100 above the tray window 211. Furthermore, the hopper bottom plate 21 is mounted above the single-disc conveyor module 3 via support columns 24. The hopper pallet driving component includes a first driving cylinder 25, the fixed end of which is located on the hopper bottom plate 21. The hopper pallet 22 is positioned opposite each other on both sides of the pallet window 211 and connected to the piston end of the first driving cylinder 25. Multiple protrusion structures 26 are provided on the side of the hopper pallet 22 closest to the pallet window 211. The number of protrusion structures 26 can be 1-3, depending on the shape and size of the pallet; in this embodiment, 3 are evenly spaced. The hopper pallet 22 is driven by the first driving cylinder 25 to extend towards the pallet window 211 to support the pallet 100. When the pallet 100 is released, the first driving cylinder 25 then drives the hopper pallet 22 to retract. Guide rails 27 are provided on both sides of the first drive cylinder 25. The hopper tray 22 is slidably mounted on the guide rails 27 by a guide slider. The first drive cylinder 25 drives the hopper tray 22 to move along the guide rails 27 on the hopper bottom plate 21.

[0026] Reference Figure 4 The single-disc conveying module 3 is mounted on the machine base 1 and located below the hopper pallet 22. It includes a first synchronous conveying mechanism, a U-shaped moving pallet 31, and a lifting mechanism. The lifting mechanism is located below the pallet window 211. It rises through the U-shaped moving pallet 31 to support the full pallet 100, and descends to bring the full pallet 100 onto the U-shaped moving pallet 31. The first synchronous conveying mechanism drives the U-shaped moving pallet 31 to convey the full pallet 100.

[0027] Furthermore, the first synchronous transmission mechanism includes a first motor 32, a first drive shaft 33, a first drive synchronous pulley 34, a first driven synchronous pulley 35, and a first synchronous belt 36. The first drive shaft 33 is located at the output end of the first motor 32, the first drive synchronous pulley 34 is located on the first drive shaft 33, the first driven synchronous pulley 35 is mounted on the machine base 1 and is located on the same straight line as the first drive synchronous pulley 34, and the first synchronous belt 36 is sleeved on the first drive synchronous pulley 34 and the first driven synchronous pulley 35. The bottom of the U-shaped moving pallet 31 is mounted on the first synchronous belt 36 through a downwardly extending clamping block 311. The bottom of the U-shaped moving pallet 31 is also provided with two guide support plates 312, and the top of the guide support plates 312 is provided with a guide rail. The bottom of the U-shaped moving pallet 31 is connected to the guide rail at the top of the guide support plates 312 through a slider. When the first synchronous belt 36 drives the U-shaped moving pallet 31 to move back and forth in a straight line, it plays a supporting, guiding, and stabilizing role. The first motor 32 drives the first drive shaft 33 to rotate, thereby driving the first synchronous belt 36 to transmit the U-shaped moving pallet 31 on it. In the attached figure of this embodiment, the first motor 32 is located in the middle of the first drive shaft 33 and is connected to the first drive shaft 33 through a reversing reducer with two output ends. In other embodiments, the first motor 32 may also be located at one end of the first drive shaft 33.

[0028] In addition, the lifting mechanism includes a top plate 37, a second motor 38, and a first lead screw 39. The second motor 38 is mounted inside the machine base 1 via a connecting frame. The first lead screw 39 is located at the output end of the second motor 38. The top plate 37 is mounted on the matching nut of the first lead screw 39. The second motor 38 drives the top plate 37 to rise and fall. Guide shafts 371 can also be provided at the four corners of the bottom of the top plate 37. The guide shafts 371 are movably mounted on the machine base 1 via linear bearings 372 and play a guiding role when the top plate 37 rises and falls. When loading materials, the second motor 38 drives the first lead screw 39 to rotate, raising the top plate 37. It then passes through the middle window of the U-shaped moving pallet 31 and rises to the bottom tray 100 position in the tray window 211. The hopper pallet 22 moves outward under the drive of the first drive cylinder 25, causing the protrusion structure 26 on the hopper pallet 22 to move away from the bottom tray 100 and release its restriction. The top plate 37 descends with one tray 100. During the descent, the first drive cylinder 25 drives the hopper pallet 22 to move towards the center, causing the protrusion structure 26 on the hopper pallet 22 to insert into the bottom of the second to last tray 100, supporting the remaining trays 100 except the bottom one. The top plate 37 descends to the U-shaped moving pallet 31 and continues to descend, leaving the trays 100 on the U-shaped moving pallet 31 so that the U-shaped moving pallet 31 can push the trays 100 filled with products into the waiting loading module 4 to wait for loading.

[0029] The waiting-to-load module 4 and the single-disc conveying module 3 are located on the same conveying line. The module includes two opposing support side plates 41 and a side positioning tray 42 on the support side plates 41. The full material tray 100 is conveyed between the support side plates 41 by the U-shaped moving tray 31 and is supported and fixed by the side positioning tray 42 to wait for material to be picked up.

[0030] Furthermore, the side positioning pallet 42 is moved horizontally on the support side plate 41 by the second drive cylinder 43, and an L-shaped positioning baffle is provided at the end of the support side plate 41 near the empty tray lifting module 6. Similar to the hopper pallet 22, the inner side of the side positioning pallet 42 is also provided with multiple protrusion structures. The side positioning pallet 42 is driven by the second drive cylinder 43, causing one side of the protrusion structure to extend towards the center to support the conveyed tray 100. When the tray 100 is released, the second drive cylinder 43 drives the side positioning pallet 42 to retract, and the support rod 61 on the vertical lifting module takes over the tray 100 and brings it into the machine base 1, ready to be conveyed to the empty tray conveying module 7. Preferably, the second drive cylinder 43 is mounted on the top of the support side plate 41 via the mounting plate 44. Guide rails are also provided on both sides of the second drive cylinder 43. The side positioning plate 42 is slidably mounted on the guide rail via the guide slider. The second drive cylinder 43 drives the side positioning plate 42 to move along the guide rail on the mounting plate 44, that is, to translate on the support side plate 41.

[0031] A loading robot 5, mounted above the waiting loading module 4, is used to transfer products from a full material tray 100. The loading robot 5 includes an X-axis moving module 51, a Y-axis moving module 52, a Z-axis moving module 53, and a product picking component. The product picking component can be either an existing vacuum nozzle or an electric gripper, selected appropriately based on the specific product. The X-axis moving module 51 is mounted above the waiting loading module 4 and the empty tray lifting module 6 via a support frame 54. An X-axis guide rail is also mounted on the side parallel to the X-axis moving module 51 via a support frame. The Z-axis moving module 53 is mounted on the X-axis moving module 51. Furthermore, the Z-axis moving module 53 is spanned across the X-axis moving module 51 and the X-axis guide rail via a crossbeam, and moves along the X-axis... The X-axis guide rail moves horizontally, and the Y-axis moving module 52 is mounted on the Z-axis moving module 53. The product picking component is mounted on the Y-axis moving module 52. The product picking component is used to pick up products from the tray 100. It is driven by the X-axis moving module 51, the Y-axis moving module 52, and the Z-axis moving module 53 to perform three-axis movements: horizontal lateral, horizontal longitudinal, and vertical lifting. The X-axis moving module 51, the Y-axis moving module 52, and the Z-axis moving module 53 include, but are not limited to, linear motors, servo motors, and lead screws, as well as various electromechanical devices, transmission devices, and control devices that can realize horizontal X-axis, Y-axis, and vertical Z-axis movements.

[0032] The empty tray lifting module 6 includes a vertical lifting module and a support rod 61 mounted on the vertical lifting module. The vertical lifting module is located at one end of the supporting side plate 41 and extends vertically into the machine base 1. It is used to drive the support rod 61 to move up and down below the waiting loading module 4 to connect the empty tray 100. The vertical lifting module includes a back plate 62, a second lead screw 63, a third motor, and guide rails 64 parallel to both sides of the second lead screw 63. The second lead screw 63 and guide rails 64 are located on the same side of the back plate 62, and the third motor is located on the other side of the back plate 62. The support rod 61 is mounted on the matching nut of the second lead screw 63 via a connecting plate 65. The bottom ends of the connecting plate 65 are provided with sliders that are slidably connected to the two guide rails 64. The third motor is connected to one end of the second lead screw 63 via a coupling, synchronous pulley, synchronous belt, or other common mechanical connection structure, and drives it to rotate. The nut on the motor then moves the connecting plate 65 and the support rod 61 up and down along the guide rails 64.

[0033] The empty tray conveying module 7, located inside the machine base 1, includes a second synchronous conveying mechanism and a belt pad 76. The second synchronous conveying mechanism extends below the support rod 61 and is staggered with the support rod 61 to receive the tray 100 on the support rod 61. The second synchronous conveying mechanism includes a fourth motor 71, a second drive shaft 72, a second drive synchronous pulley 73, a second driven synchronous pulley 74, and a second synchronous belt 75. The second drive shaft 72 is located at the output end of the fourth motor 71. The second drive synchronous pulley 73 is located on the second drive shaft 72. The second driven synchronous pulley 74 is mounted inside the machine base 1 and is aligned with the second drive synchronous pulley 73. The second synchronous belt 75 is fitted onto the second drive synchronous pulley 73 and the second driven synchronous pulley 74. The belt pad 76 is mounted inside the machine base 1 and is inserted into the second synchronous belt 75 to prevent the second synchronous belt 75 from sagging and deforming when conveying the tray 100. During the feeding process, the support rod 61 and the second synchronous belt 75 are intersected without interference. The support rod 61 will lower the empty material tray 100 onto the second synchronous belt 75. The support rod 61 continues to descend and detaches from the material tray 100. The empty tray is then conveyed to the discharge port by the second synchronous belt 75. Once conveyed to the discharge port, it can slide directly into the pre-prepared collection box.
