[0023] The following description, in conjunction with the accompanying drawings, further illustrates the proposed solution:

[0024] See appendix Figures 1-20 An automatic flattening and punching machine for L-shaped shafts includes a worktable 1, a feeding mechanism 2, a loading and transfer mechanism, a handling mechanism 5, a punching mechanism 6, and a discharge mechanism 9.

[0025] The workbench 1 is provided with a transfer station 11, a stamping station 12, a punching station 13 and a discharge station 14 that are evenly spaced along a Y-axis.

[0026] The feeding mechanism 2 is used to transport the L-shaped shaft 100 to be processed.

[0027] The L-shaped shaft 100 includes a first shaft portion 101 and a second shaft portion 102 that are perpendicular to each other. When the first shaft portion 101 is placed vertically along a Z-axis and the second shaft portion 102 is placed horizontally along an X-axis, the L-shaped shaft 100 is in an upright state. When the first shaft portion 101 is placed horizontally along a Y-axis and the second shaft portion 102 is placed horizontally along an X-axis, the L-shaped shaft 100 is in a flat state. The X-axis is perpendicular to the Y-axis, and the Z-axis is perpendicular to the plane where the X-axis and Y-axis intersect.

[0028] The feeding mechanism 2 includes a feeding outlet 22 located at the transfer station 11; the L-shaped shaft 100 is output from the feeding outlet 22 of the feeding mechanism 2 in an upright state.

[0029] The feeding transfer mechanism is located at the transfer station 11 and is used to receive the L-shaped shaft 100 output by the feeding mechanism 2 and flip the L-shaped shaft 100 to a flat position.

[0030] The transport mechanism 5 is used to transport the L-shaped shaft 100, which is in a flat position at the transfer station 11, to the stamping station 12, the punching station 13 and the unloading station 14 in sequence.

[0031] A flattening die is provided at the stamping station 12; a punching die is provided at the punching station 13; and the stamping mechanism 6 is used to stamp the L-shaped shaft 100 on the flattening die and the punching die.

[0032] The discharge mechanism 9 is located at the discharge station 14 and is used to receive the processed L-shaped shaft 100.

[0033] This technical solution, through the cooperation of the feeding mechanism 2, the loading transfer mechanism, the handling mechanism 5, the stamping mechanism 6, and the unloading mechanism 9, realizes the automatic loading, handling, and stamping of the L-shaped shaft 100, replacing manual operation, saving labor, and revolutionizing the bottleneck of manual operation in this type of product industry. It improves work safety and efficiency, while also improving the stability and consistency of product quality.

[0034] The transport mechanism 5 includes a three-axis drive mechanism 53, a transport frame 52, and a transport fixture 51; the three-axis drive mechanism 53 is connected to the transport frame 52 to drive the transport frame 52 to move along the X-axis, Y-axis, and Z-axis; the transport fixture 51 is mounted on the transport frame 52.

[0035] The transport fixture 51 is provided in at least three sets, and each set of transport fixtures 51 is evenly spaced along the Y-axis. The distance between two adjacent sets of transport fixtures 51 is the same as the distance between two adjacent workstations. The transport fixture 51 is used to clamp or release the L-shaped shaft 100.

[0036] The flattening die includes a lower flattening die 71 and an upper flattening die 72; the punching die includes a lower punching die 81 and an upper punching die 82; the stamping mechanism 6 includes a vertically movable stamping base 61, on which the upper flattening die 72 and the upper punching die 82 are both mounted; the lower flattening die 71 and the lower punching die 81 are mounted on a die base 62, which is fixed to a worktable.

[0037] The lower punching die 81 and the upper punching die 82 are provided with die clearance portions for the transport clamp 51 to extend into; the transport clamp 51 always clamps the L-shaped shaft 100 when the stamping mechanism 6 is working.

[0038] The conveying mechanism 5 of this technical solution can simultaneously convey multiple workpieces and operate at multiple stations concurrently. This technical solution combines the stamping process, and the stamping mechanism 6 can simultaneously perform flattening and punching operations, significantly improving processing efficiency. During the flattening and punching process, the conveying fixture 51 always clamps the L-shaped shaft 100, eliminating the need for additional fixing fixtures. This also avoids the impact on processing quality caused by the clamping position shift due to release and re-clamping, further improving the stability and consistency of product quality.

[0039] The stamping mechanism can be achieved using an existing punch press. The flattening die for flattening the workpiece and the punching die for punching are existing technologies, therefore they are not illustrated in the accompanying drawings.

[0040] In this embodiment, the three-axis drive mechanism 53 is a three-axis motion manipulator, which moves flexibly and accurately.

[0041] The feeding mechanism 2 includes a feeding track 21 for conveying L-shaped shafts 100. The feeding track 21 extends along the Y-axis, and the feeding outlet 22 is located at the extended end of the feeding track 21. The L-shaped shafts 100 are arranged vertically one by one within the feeding track 21. In this embodiment, the feeding mechanism 2 is a conventional feeding vibratory feeder.

[0042] The feeding and transfer mechanism includes a receiving mechanism 3 and a flipping mechanism 4.

[0043] The receiving mechanism 3 includes a receiving seat 31 and a pressing mechanism; the receiving seat 31 is provided with a receiving channel 311 that connects with the feeding outlet 22. The pressing mechanism is installed on one side of the receiving channel 311 and is used to press the L-shaped shaft 100 that falls into the receiving channel 311.

[0044] The flipping mechanism 4 includes a fixed base 41, a flipping base 42, and a transfer clamp 43; the flipping base 42 is rotatably mounted on the fixed base 41 around the X-axis to switch between an upright position and a horizontal position; the flipping base 42 is provided with a transfer position 421 for placing the L-shaped shaft 100, and the transfer position 421 is opposite to the receiving channel 311 when the flipping base 42 is in the upright position; the transfer clamp 43 is mounted on the flipping base 42 and is used to clamp the L-shaped shaft 100 of the receiving channel 311.

[0045] In this embodiment, the flip seat 42 can be switched to a horizontal position by rotating 90° from the upright position.

[0046] When the feeding mechanism 2 of this technical solution conveys the L-shaped shaft 100, it must be in an upright state so that they can be arranged compactly one by one.

[0047] This technical solution sets up a feeding transfer mechanism at the output of the feeding mechanism 2. The receiving channel 311 of the receiving mechanism 3 connects with the feeding outlet 22 of the feeding track 21 to receive materials. The L-shaped shaft 100 is clamped and flipped by the flipping mechanism 4 to switch it to a flat position, which is convenient for the handling fixture 51 to clamp.

[0048] The clamping mechanism includes a clamping block that can be brought near or away from the receiving channel 311 for clamping or loosening the L-shaped shaft 100.

[0049] The transfer clamp 43 includes a transfer chuck 431 that can be opened or closed to release or clamp the L-shaped shaft 100; a through hole 422 is provided at the transfer position 421, and the transfer chuck 431 passes through the through hole 422; the receiving channel 311 is provided with a receiving clearance part 312; when the flipping seat 42 is in the upright position, the transfer chuck 431 extends into the receiving clearance part 312 to clamp the L-shaped shaft 100 of the receiving channel 311 and fix it on the flipping seat 42.

[0050] The transfer position 421 is provided with a transfer clearance 423; the transport clamp 51 includes a transport chuck 511 that can be opened or closed to release or clamp the L-shaped shaft 100; the transport chuck 511 extends into the transfer clearance 423 when the flip seat 42 is in a horizontal position to clamp the L-shaped shaft 100 of the transfer position 421; the transfer chuck 431 releases the L-shaped shaft 100 when the transport chuck 511 clamps the L-shaped shaft 100.

[0051] In this embodiment, the transfer clamp 43 includes a pneumatic gripper that drives the transfer chuck 431 to open or close; the transport angle includes a pneumatic gripper that drives the transport chuck 511 to open or close.

[0052] This technical solution first uses a receiving mechanism 3 to receive the L-shaped shaft 100. The receiving channel 311 can be provided with a receiving clearance part 312 to facilitate the transfer clamp 43 to clamp the workpiece. The transfer clamp 43 is set on the flipping seat 42. After clamping the L-shaped shaft 100, it flips synchronously with the flipping seat 42 to play the role of transfer and fixation. The flipping seat 42 is also provided with a transfer clearance part 423 to facilitate the transport chuck 511 to extend into and clamp the workpiece.

[0053] The receiving channel 311 includes a waiting position 313 and a transfer position 314 arranged side by side; the waiting position 313 is adjacent to the feeding outlet 22; the waiting position 313 and the transfer position 314 are respectively used to place an L-shaped shaft 100; the clamping mechanism is used to clamp or release the L-shaped shaft 100 in the waiting position 313, and the transfer clamp 43 is used to clamp the L-shaped shaft 100 in the transfer position 314.

[0054] In this embodiment, the receiving seat 31 is equipped with a material sensing probe for sensing whether there is a workpiece on the transfer position 314. When the receiving mechanism 3 receives the L-shaped shaft 100, when an L-shaped shaft 100 enters the transfer position 314, the L-shaped shaft 100 in the waiting position 313 is pressed and fixed, and the flipping mechanism 4 begins to clamp the L-shaped shaft 100 in the transfer position 314 and drives the L-shaped shaft 100 to flip and switch states.

[0055] This technical solution sets a waiting position 313 and a transfer position 314 in the receiving channel 311. The L-shaped shaft 100 in the waiting position 313 is pressed and fixed, which can intercept the L-shaped shaft 100 in the feeding track 21 and prevent the L-shaped shaft 100 behind from continuing to move forward and push, causing the workpiece to shift. The L-shaped shaft 100 in the transfer position 314 is not affected by the L-shaped shaft 100 in the feeding track 21, which makes it easier for the transfer fixture 43 to accurately clamp it.

[0056] The clamping mechanism includes a first clamping mechanism 32 and a second clamping mechanism 33; the first clamping mechanism 32 is used to clamp the first shaft portion 101 of the L-shaped shaft 100; the second clamping mechanism 33 is used to clamp the second shaft portion 102 of the L-shaped shaft 100.

[0057] The receiving channel 311 includes a first receiving area for receiving a first shaft portion 101 and a second receiving area for receiving a second shaft portion 102; the receiving seat 31 is provided with a groove communicating with the first receiving area; the first pressing mechanism 32 includes a first pressing block 321; the first pressing block 321 is movably mounted on the groove along the X-axis to be close to or away from the first receiving area; the second pressing mechanism 33 includes a second pressing block 331, the second pressing block 331 is movably mounted on the top side of the receiving seat 31 along the Z-axis to be close to or away from the second receiving area.

[0058] The first pressing mechanism 32 further includes a first pressing cylinder 322 and a guide seat 323; the first pressing cylinder 322 is mounted on the receiving seat 31, and one end of the guide seat 323 is slidably mounted on the cylinder body of the first pressing cylinder 322 through a guide rail and guide groove structure; the other end of the guide seat 323 is connected to the telescopic rod of the first pressing cylinder 322, and the first pressing block 321 is fixed on the guide seat 323.

[0059] The second pressing mechanism 33 also includes a second pressing cylinder 332, and the second pressing block 331 is connected to the telescopic rod of the second pressing cylinder 332.

[0060] In this technical solution, both the first shaft portion 101 and the second shaft portion 102 of the L-shaped shaft component 100 can be clamped and fixed by a clamping mechanism, ensuring stable positioning. The first pressure block 321, through its cooperation with the slide groove, guide seat 323, and guide rail 324, provides movable guidance, preventing deviation and improving the accuracy and stability of clamping.

[0061] The first receiving area is provided with two spaced-apart pressure-bearing protrusions 315; the space between the two pressure-bearing protrusions 315 forms a receiving clearance 312; the second receiving area is provided with two spaced-apart support protrusions; the space between the two support protrusions forms another receiving clearance 312.

[0062] The first pressing block 321 has two pressing parts 3211, which are respectively opposite to two pressure-bearing protrusions 315. A limiting block is provided above each of the two supporting protrusions; the second pressing block is opposite to one of the supporting protrusions, and the limiting block above the supporting protrusion has a notch corresponding to the second pressing block.

[0063] When the first pressing block 321 and the second pressing block 424 are far away from the receiving channel 311, the L-shaped shaft 100 is not pressed, but the limiting block still plays a certain limiting role, so that the L-shaped shaft 100 can smoothly transition from the waiting position to the transfer position.

[0064] Two transfer clamps 43 are provided, and the two transfer clamps 43 are respectively used to clamp or release the middle part of the first shaft 101 and the second shaft 102; each set of transport clamps 51 includes two transport clamps 51; the two transport clamps 51 in the same set are used to clamp or release the two ends of the first shaft 101 together; one of the transport clamps 51 is equipped with a sensing probe.

[0065] During the flipping process, the L-shaped shaft 100 of this technical solution uses two transfer clamps 43 to clamp the middle part of the first shaft 101 and the second shaft 102 respectively, which has high stability; at the same time, space is left at both ends of the first shaft 101 for the transport clamp 51 to clamp.

[0066] During the handling and loading process, the L-shaped shaft 100 is clamped by two handling fixtures 51. The double clamping setup can maintain the balance and stability of the workpiece without affecting the stamping process of the second shaft 102, especially during stamping.

[0067] This technical solution enables the feeding process to proceed efficiently and stably through the rational distribution and layout of the clearance space and the cooperation of the two clamps.

[0068] The flipping mechanism 4 further includes a flipping drive mechanism 44; the fixed base 41 includes two symmetrically arranged upright plates 411 and a rotating shaft 412 rotatably mounted between the two upright plates 411. The flipping seat 42 is fixed on the rotating shaft 412. The flipping drive mechanism 44 is connected to the rotating shaft 412 to drive the rotating shaft 412 to rotate, thereby driving the flipping seat 42 to rotate to switch positions. The receiving seat 31 is fixed between the two upright plates 411. The fixed base 41 is provided with a limiting post 413, and the flipping seat 42 abuts against the limiting post 413 when it is in a horizontal position. The flipping drive mechanism 44 is a rotary cylinder.

[0069] The flip seat 42 is provided with multiple pairs of positioning protrusions 424. Each pair of positioning protrusions consists of two spaced positioning protrusions 424. The space between the two positioning protrusions 424 in each pair of positioning protrusions 424 is used to accommodate the L-shaped shaft 100.

[0070] In this embodiment, the first shaft portion 101 and the second shaft portion 102 of the L-shaped shaft member 100 are respectively positioned by two pairs of spaced positioning protrusions 424. The through hole 422 is located between the two pairs of positioning protrusions 424.

[0071] The discharge mechanism 9 includes a discharge slide 91, which has an inlet 911 for receiving the processed L-shaped shaft 100; a hole detection mechanism 92 is provided above the inlet 911; the hole detection mechanism 92 is used to detect whether there are punched holes on the second shaft portion 102 of the processed L-shaped shaft 100, so as to ensure the quality of the discharged finished product.

[0072] like Figure 20 As shown, the workbench 1 is provided with a mounting groove 15 extending along the Y-axis; the mounting groove 15 is provided with a plurality of sliders 16 that can slide along the mounting groove 15, and the sliders 16 are provided with screw holes 161. The feeding transfer mechanism and the discharging mechanism 9 are connected to the screw holes 161 of the sliders 16 by screws.

[0073] Specifically, the feeding transfer mechanism also includes a base 30; the receiving seat 31, the fixing seat 41, and the flipping drive mechanism 44 are fixed on the base 30. The discharging mechanism 9 also includes a support frame 93, and the discharging slide 91 is fixedly connected to the support frame 93. The bottom of both the base 30 and the support frame 93 is provided with a strip hole for screws to pass through, and the strip hole extends along the X-axis direction.

[0074] During installation, the base 30 and support frame 93 are connected to the screw holes of the strip hole 162 and the corresponding slider 16 respectively by screws. The screws are tightened until they abut against the bottom of the mounting groove to fix the position. When the loading transfer mechanism or unloading mechanism 9 needs to be adjusted, the screws can be loosened, and the slider 16 can be moved to the appropriate position along the Y-axis, then moved to the appropriate position along the strip hole 162, and the screws can be tightened.

[0075] The loading transfer mechanism and unloading mechanism 9 of this technical solution are fixed by screws and slider 16, and can be moved and installed in a suitable position along the Y-axis, which is convenient for installation alignment and adding, removing or changing work stations; and the position on the X-axis can be finely adjusted by the slot and screws, which is convenient for alignment with the handling fixture 51.

[0076] The initial position of the flipping mechanism 4 is upright, and the transfer chuck 431 of the transfer clamp 43 opens at the receiving clearance part 312; the three sets of transfer clamps 51 of the conveying mechanism 5 are respectively the first set of transfer clamps 51A, the second set of transfer clamps 51B, and the third set of transfer clamps 51C along the Y-axis; the distance between two adjacent sets of transfer clamps 51 is greater than the width of the loading transfer mechanism when the flipping seat 42 is in the horizontal position; the working process of this technical solution is as follows:

[0077] 1. The feeding mechanism 2 transports the L-shaped shaft 100 to the transfer station 11 where it is received by the loading transfer mechanism;

[0078] 2. The receiving channel 311 of the receiving mechanism 3 receives the L-shaped shaft 100 output from the feeding outlet 22 of the feeding track 21. The L-shaped shaft 100 first arrives at the waiting position 313 and then enters the transfer position 314. When an L-shaped shaft 100 enters the transfer position 314, the pressing block of the pressing mechanism approaches the receiving channel 311 to press the L-shaped shaft 100 in the waiting position 313, preventing the L-shaped shaft 100 of the feeding track 21 from continuing to move forward. Then, the transfer clamp 43 clamps the L-shaped shaft 100 in the transfer position 314, and the flipping seat 42 flips 90° to reach the horizontal position, so that the L-shaped shaft 100 is switched to the flat position.

[0079] 3. The third set of transport fixtures 51C of the transport mechanism 5 moves to the transfer station 11 to clamp the L-shaped shaft 100 on the flipping seat 42, such as... Figure 5 As shown, the transfer chuck 431 opens, and the transport fixture 51 moves the L-shaped shaft 100 away from the transfer station 11;

[0080] 4. The flipping seat 42 returns to the upright position, and then the first pressing block 321 and the second pressing block 331 move away from the receiving channel 311. The L-shaped shaft 100 of the waiting position 313 enters the transfer position 314, and the operation of step 2 is repeated.

[0081] 5. The second set of transport fixtures 51B of the transport mechanism 5 moves to the transfer station 11 to clamp the L-shaped shaft 100, as follows. Figure 6 As shown, the third set of transport fixtures 51C drives the L-shaped shaft 100 to the flattening lower die 71 of the stamping station 12, the stamping seat 61 of the stamping mechanism 6 moves down, and the flattening upper die 72 flattens the second shaft part 102 of the L-shaped shaft 100 on the flattening lower die 71.

[0082] 6. The stamping seat 61 of the stamping mechanism 6 moves upward, the second set of handling fixtures 51B moves the L-shaped shaft 100 away from the transfer station 11, and the third set of handling fixtures 51C moves the L-shaped shaft 100 away from the stamping station 12; then repeat the operation of step 4.

[0083] 7. The first set of transport fixtures 51A of the transport mechanism 5 moves to the transfer station 11 to clamp the L-shaped shaft 100, as follows: Figure 7 As shown, the second set of transport fixtures 51B drives the L-shaped shaft 100 to the flattening die 71 of the stamping station 12, and the third set of transport fixtures 51C drives the L-shaped shaft 100 to the punching die 81 of the punching station 13. The stamping seat 61 of the stamping mechanism 6 moves down, and at the same time, the second shaft portion 102 of the L-shaped shaft 100 in the stamping station 12 is flattened, and the second shaft portion 102 of the L-shaped shaft 100 in the punching station 13 is punched.

[0084] 8. The stamping seat 61 of the stamping mechanism 6 moves upward, as follows: Figure 8As shown, the first set of transport fixtures 51A of the transport mechanism 5 drives the L-shaped shaft 100 to the stamping station 12, the second set of transport fixtures 51B drives the L-shaped shaft 100 to the punching station 13, and the third set of transport fixtures 51C drives the L-shaped shaft 100 to the discharge station 14. After the hole position detection mechanism 92 detects that the hole position is qualified, the L-shaped shaft 100 on the third set of transport fixtures 51C is lowered to the discharge sliding output; if the workpiece fails the inspection, it is transported to the recycling bin.

[0085] 9. The L-shaped shaft 100 on the first set of transport fixtures 51A and the second set of transport fixtures 51B continues to repeat the operation of the third set of transport fixtures 51C until the L-shaped shaft 100 on the first set of transport fixtures 51A reaches the discharge station 14 to complete the discharge.

[0086] 10. Repeat steps 1-9.

[0087] The above preferred embodiments should be regarded as illustrative examples of the embodiments of the present application.
