[0035] The directional terms such as "up," "down," "left," "right," "front," "back," "top," and "bottom" (if present) used in the specification and claims of this utility model are defined according to the position of the structures in the drawings and the relative positions of the structures, and are only for the purpose of clarity and convenience in expressing the technical solution. It should be understood that the use of directional terms should not limit the scope of protection claimed in this application.

[0036] Please see Figures 1-3 , Figure 5 , Figure 10 and Figure 14 An automatic loading and unloading lathe equipment includes a worktable 10, a lathe 20, an air blowing mechanism 30, a loading mechanism 40, a material transfer mechanism 50, a waste collection mechanism 60, and a CNC box 70.

[0037] The lathe 20 is fixed on the worktable 10 and includes a spindle 21 extending in the X direction and a cutting tool 22 that cooperates with the spindle 21. The spindle 21 is used to clamp the workpiece 100 and drive the workpiece 100 to rotate. The cutting tool 22 cooperates with the spindle 21 to process the workpiece 100.

[0038] The loading mechanism 40 is mounted on the worktable 10. It includes a sliding seat 42 that slides on the worktable 10 and a loading tray 43 mounted on the sliding seat 42. The sliding seat 42 can drive the loading tray 43 to move along the Y direction. The loading tray 43 is used to place the workpieces 100 to be processed and processed.

[0039] An air blowing mechanism 30 is disposed between the lathe 20 and the loading mechanism 40. It includes an air blowing element 31, which is used to blow away metal debris from the surface of the machined workpiece 100. In this embodiment, the workpiece 100 has a head 101 and a body 102 connected to the head 101. The lathe 20 processes the head 101 of the machined workpiece 100, and the air blowing element 31 can blow away the metal debris from the surface of the head 101 of the machined workpiece 100.

[0040] The transfer mechanism 50 is mounted on the worktable 10 and is used to transfer the machined workpiece 100 on the spindle 21 and the workpiece 100 to be processed on the loading tray 43. The transfer mechanism 50 includes a transfer robot 51 that can be displaced along the X and Z directions. The transfer robot 51 includes a first robot 511 facing downward along the Z direction, a second robot 512 facing towards the lathe 20 along the X direction, and a first drive device 513 that is inclined. The first drive device 513 is connected to the first robot 511 and the second robot 512 through a connector 514 and is used to drive the connector 514 to rotate so as to interchange the positions of the first robot 511 and the second robot 512. More specifically, the first robot 511 and the second robot 512 have completely identical structures and functions. In this embodiment, the first drive device 513 is a cylinder.

[0041] In the initial state, the first robot arm 511 faces downward along the Z-axis, and the second robot arm 512 faces towards the lathe 20 along the X-axis. The first robot arm 511 and the air blowing component 31 are arranged in a straight line along the X-axis, and the second robot arm 512 and the spindle 21 are arranged in a straight line along the X-axis. After the first drive device 513 drives the first robot arm 511 and the second robot arm 512 to exchange positions, the first robot arm 511 faces towards the lathe 20 along the X-axis, and the second robot arm 512 faces downward along the Z-axis. The first robot arm 511 and the spindle 21 are arranged in a straight line along the X-axis, and the second robot arm 512 and the air blowing component 31 are arranged in a straight line along the X-axis.

[0042] At least a portion of the waste collection mechanism 60 is located below the lathe 20, and it is used to collect and transfer the metal waste generated by the lathe 20.

[0043] The CNC box 70 is used to control the coordinated operation of the lathe 20, the loading mechanism 40, the air blowing mechanism 30, the material transfer mechanism 50, and the waste collection mechanism 60.

[0044] As described above, the automatic loading and unloading lathe equipment provided by this utility model, through the cooperation of the transfer robot 51, the loading tray 43, and the spindle 21, enables the transfer robot 51 to transfer the workpiece 100 to be processed on the loading tray 43 to the lathe 20 for processing, and to transfer the processed workpiece 100 on the spindle 21 to the loading tray 43, thus achieving automatic loading and unloading without relying on manual operation; through the cooperation of the first robot 511, the second robot 512, and the first drive device 513, its structure is compact, allowing the first robot 511 and the second robot 512 to interchange positions and alternately operate, realizing automatic loading and unloading. The robotic arm 51 can grip the machined workpiece 100 on the spindle 21 within the lathe 20 and place the workpiece 100 to be processed on the spindle 21, thus efficiently transferring the workpiece 100 between the robotic arm 51 and the lathe 20. Through the cooperation of the robotic arm 51 and the air blowing mechanism 30, the robotic arm 51 can move the machined workpiece 100 on the spindle 21 directly above the air blowing mechanism 31, automatically blowing away metal shavings from the surface of the machined workpiece 100 without manual intervention. Furthermore, the shavings collection mechanism 60 automatically collects and transfers metal shavings, eliminating the need for manual labor. In summary, this automatic loading and unloading lathe equipment enables automatic loading and unloading of CNC lathes, automatic workpiece blowing, and automatic collection of metal shavings, reducing labor costs and improving production efficiency.

[0045] Please see Figure 4The lathe 20 also includes a bed 23 fixed on the worktable 10, a saddle 24 slidably mounted on the bed 23, a fixed seat 25 mounted on the saddle 24, a movable plate 26 slidably mounted on the fixed seat 25, and a tool post 27 mounted on the movable plate 26. The tool post 27 is used to mount the cutting tool 22. The saddle 24 can drive the cutting tool 22 to move along the X-axis, and the movable plate 26 can drive the cutting tool 22 to move along the Y-axis, thereby enabling the cutting tool 22 to cooperate with the spindle 21 to process the workpiece 100.

[0046] Please see Figure 5 and Figure 6 The connector 514 has a first mounting plate 515, a second mounting plate 516, and a connecting part 517 connecting the first mounting plate 515 and the second mounting plate 516. The connecting part 517 is installed on the rotating end 5131 of the first drive device 513. The first mounting plate 515 and the second mounting plate 516 are centrally symmetrically distributed with the center point of the connecting part 517 as the reference, ensuring that after the first drive device 513 drives the connector 514 to rotate 180°, the positions of the first mounting plate 515 and the second mounting plate 516 are interchanged, thereby realizing that the first robot arm 511 and the second robot arm 512 can interchange positions.

[0047] Furthermore, the first mounting plate 515 has a first mounting surface 5151 for mounting the first robot arm 511, and the second mounting plate 516 has a second mounting surface 5161 for mounting the second robot arm 512. The first mounting surface 5151 and the second mounting surface 5161 are perpendicular to each other. In this embodiment, in the initial state, the first mounting surface 5151 is located on the same plane as the horizontal plane, and the second mounting surface 5161 is located on the same plane as the vertical plane. This arrangement allows the first robot arm 511 mounted on the first mounting surface 5151 to face downwards along the Z direction, and the second robot arm 512 mounted on the second mounting surface 5161 to face towards the lathe 20 along the X direction. This achieves the perpendicularity of the first robot arm 511 and the second robot arm 512, enabling the transfer robot arm 51 to cooperate with the spindle 21, the air blowing mechanism 30, and the loading mechanism 40. When the positions of the first mounting plate 515 and the second mounting plate 516 are interchanged, the first mounting surface 5151 is located on the same plane as the vertical surface, and the second mounting surface 5161 is located on the same plane as the horizontal surface, thereby realizing the interchange of the position and function of the first robotic arm 511 and the second robotic arm 512.

[0048] Please see Figure 2 , Figure 7 and Figure 8The material transfer mechanism 50 also includes a fixed frame 52 fixed on the worktable 10, a sliding unit 53 set on the fixed frame 52, and a lifting unit 54 connected to the sliding unit 53. The lifting unit 54 is connected to the transfer robot 51 and can drive the transfer robot 51 to move along the Z direction. The sliding unit 53 can drive the lifting unit 54 to move along the X direction. Then the transfer robot 51 follows the lifting unit 54 to move along the X direction, so that the transfer robot 51 can move along the Z and X directions to realize the operation and cooperation of the transfer robot 51 with the main shaft 21, the air blowing mechanism 30, and the loading mechanism 40.

[0049] Furthermore, the sliding unit 53 includes a first guide rail 532 fixed to the fixed frame 52 and extending along the X direction, a slide plate 531 slidably mounted on the first guide rail 532, and a first drive assembly for driving the slide plate 531 to slide along the first guide rail 532. The slide plate 531 is provided with a bracket 538 slidably connected to the lifting unit 54. During operation, the first drive assembly drives the slide plate 531 to slide along the first guide rail 532, thereby causing the lifting unit 54 to move along the X direction.

[0050] More specifically, the first drive assembly includes a first drive motor 533, a first drive wheel 534, a first transmission wheel 535, a first transmission belt 536, and a first clamping member 537. The output end of the first drive motor 533 is equipped with the first drive wheel 534 and is used to drive the first drive wheel 534 to rotate. The first drive wheel 534 and the first transmission wheel 535 are respectively rotatably mounted on the fixed frame 52 and distributed at both ends of the first guide rail 532. The first drive wheel 534 and the first transmission wheel 535 are connected by the first transmission belt 536. The first clamping member 537 is fixed on the first transmission belt 536 and is fixedly connected to the slide plate 531. During operation, the first drive motor 533 drives the first drive wheel 534 to rotate, thereby driving the first transmission belt 536 to rotate, which in turn causes the first transmission belt 536 to drive the slide plate 531 to slide along the first guide rail 532, realizing the displacement of the lifting unit 54 and the transfer robot 51 in the X direction.

[0051] Furthermore, the lifting unit 54 includes a lifting column 541 slidably mounted on a bracket 538, a second guide rail 542 extending along the Z-direction on the lifting column 541, and a second drive assembly for driving the lifting column 541 to rise and fall. The bracket 538 is provided with a guide block 539 slidably connected to the second guide rail 542. The lower end of the lifting column 541 is connected to the first drive device 513 via a connecting plate 546. The second guide rail 542 and the guide block 539 cooperate to limit the movement of the lifting column 541, thereby making the lifting of the lifting column 541 more stable. During operation, the second drive assembly drives the lifting column 541, which, under the limiting action of the second guide rail 542 and the guide block 539, smoothly moves along the Z-direction, thereby driving the transfer robot 51 to move along the Z-direction.

[0052] More specifically, the second drive assembly includes a second drive motor 543, a drive gear 544, and a transmission rack 545. The second drive motor 543 is located on the side of the bracket 538 away from the lifting column 541. The output end of the second drive motor 543 is equipped with the drive gear 544 and is used to drive the drive gear 544 to rotate. The transmission rack 545 is fixed to the side wall of the lifting column 541 and extends along the Z-direction, and the transmission rack 545 is meshed with the drive gear 544. During operation, the second drive motor 543 drives the drive gear 544 to rotate, thereby driving the lifting column 541 to move along the Z-direction via the transmission rack 545.

[0053] Please see Figure 2 , Figure 9 and Figure 13 The loading mechanism 40 also includes a base 41 mounted on the worktable 10, a third guide rail 44 extending along the Y direction on the base 41, and a third drive assembly for driving the sliding seat 42 to slide along the third guide rail 44. The sliding seat 42 is provided with a limiting block 421 for positioning the loading tray 43. More specifically, the loading tray 43 is provided with several loading slots 431 for placing workpieces 100. The loading slots 431 cooperate with the head 101 of the workpiece 100 to achieve placement; the several loading slots 431 are evenly distributed in a matrix. During operation, the third drive assembly drives the sliding seat 42 to slide along the third guide rail 44, thereby causing the loading tray 43 to move along the Y direction. When the loading tray 43 is full of a row of loading slots 431 along the X direction, the third drive assembly drives the loading tray 43 to move along the Y direction so that the next row of empty loading slots 431 can cooperate with the transfer robot 51.

[0054] More specifically, the third drive assembly includes a third drive motor 45, a second drive wheel 46, a second transmission wheel 47, a second transmission belt 48, and a second clamping member 49. The output end of the third drive motor 45 is equipped with the second drive wheel 46, which drives the second drive wheel 46 to rotate. The second drive wheel 46 and the second transmission wheel 47 are rotatably mounted on the base 41 and distributed at both ends of the third guide rail 44. The second drive wheel 46 and the second transmission wheel 47 are connected by the second transmission belt 48. The second clamping member 49 is fixed on the second transmission belt 48 and is fixedly connected to the sliding seat 42. During operation, the third drive motor 45 drives the second drive wheel 46 to rotate, thereby driving the second transmission belt 48 to rotate, which in turn drives the sliding seat 42 to slide along the third guide rail 44, realizing the displacement of the loading tray 43 in the Y direction.

[0055] Please see Figure 2 and Figure 10The upper surface of the air blowing component 31 is provided with several air blowing holes 311. The air blowing holes 311 are evenly distributed in a circle. This arrangement can make the air blowing more uniform, and the effect of blowing away metal waste on the processed workpiece 100 is better, thereby improving the blowing efficiency.

[0056] More specifically, the air blowing mechanism 30 also includes a waste chip collection box 32. The air blowing element 31 is disposed in the cavity of the waste chip collection box 32. The waste chip collection box 32 can collect some of the metal waste chips blown off from the processed workpiece 100, thereby improving the cleanliness of the automatic loading and unloading lathe equipment.

[0057] Please see Figure 3 , Figure 4 , Figure 11 and Figure 12 The waste chip collection mechanism 60 includes a waste chip collection funnel 61 disposed below the lathe 20, a waste chip collection box 63 for collecting metal waste chips, and a transfer channel 62 with its two ends communicating with the waste chip collection funnel 61 and the waste chip collection box 63, respectively. The worktable 10 has a downward-facing waste chip outlet 11 connected to the waste chip collection funnel 61. In this embodiment, the waste chip outlet 11 is funnel-shaped. The waste chip collection funnel 61 guides the metal waste chips into the transfer channel 62, which has a built-in conveyor belt that transports the metal waste chips falling into the transfer channel 62 to the waste chip collection box 63.

[0058] Furthermore, the bed 23 is located above the chip outlet 11, and the upper surface of the saddle 24 is provided with a downwardly inclined chip guide slope 241. The chip guide slope 241 facilitates the sliding of metal chips on the lathe 20 from the saddle 24, thereby falling into the chip collection funnel 61, reducing the accumulation of metal chips in the lathe 20 and improving the cleanliness of the lathe 20.

[0059] Please see Figure 1 A housing 12 is fixed on the worktable 10. The housing 12 covers the outer perimeter of the lathe 20. The housing 12 can effectively prevent metal scraps from splashing when the lathe 20 processes the workpiece 100, thereby improving the cleanliness of the lathe 20.

[0060] Furthermore, the top of the outer casing 12 is provided with a clearance opening 122 for avoiding the transfer robot 51. A movable baffle 121 for covering the clearance opening 122 is movably disposed on the outer casing 12, and the movable baffle 121 is driven by a second drive device 123. In this embodiment, the second drive device 123 is a cylinder. During operation, the CNC box 70 controls the second drive device 123 to drive the movable baffle 121 away from or towards the clearance opening 122 in the X direction.

[0061] The workflow of the automatic loading and unloading lathe equipment in this embodiment is as follows: In the initial state, the transfer robot 51 is located directly above the loading tray 43; the first robot 511 is facing downward along the Z direction, and the second robot 512 is facing towards the lathe 20 along the X direction, and the loading tray 43 holds the workpiece 100 to be processed.

[0062] S1. Initial loading: The transfer robot 51 moves downward along the Z direction so that the first robot 511 grips the workpiece 100 to be processed on the loading tray 43, and the transfer robot 51 returns to its initial position; then, the transfer robot 51 moves closer to the lathe 20 along the X direction. At the same time, the first drive device 513 rotates the connecting piece 514 to switch the positions of the first robot 511 and the second robot 512. The first robot 511 faces the direction closer to the lathe 20 along the X direction, and the second robot 512 faces downward along the Z direction; the second drive device 123 drives the movable baffle 121 away from the clearance opening 122 along the X direction.
