The transfer component 5 is arranged above the feeding conveyor belt 2, and the guide track component 6 is arranged on the side of the feeding conveyor belt 2. The pushing component 7 is arranged at the bottom of the guide track component 6. The pushing component 7 is used to push the spring on the guide track component 6 to the material receiving and flipping component 8. The material receiving and flipping component 8 is arranged at the output end of the guide track component 6. The material receiving and flipping component 8 flips the horizontally placed spring 90 degrees to make it stand up, and the transfer robot 9 takes the workpiece on the material receiving and flipping component 8 away.

[0031] In this embodiment, the lateral motion module 3 and the longitudinal motion module 4 are modules in the prior art that can realize linear motion, such as a servo slide, a motion module coordinated by a motor, a synchronous wheel, and a synchronous belt, etc. There are many structures in the prior art that can drive the device to perform linear motion, and their specific structures and working principles will not be described in detail here.

[0032] Specifically, the transfer assembly 5 includes a motor mounting base 52 that is transmission-connected to the longitudinal motion module 4, the surface of the motor mounting base 52 is fixedly connected with a rotating motor 51 by bolts, the output shaft of the rotating motor 51 is transmission-connected with a clamping cylinder 53 through a coupling, and the output shaft of the clamping cylinder 53 is fixedly connected with a clamping block 54 by bolts. The lateral motion module 3 drives the transfer assembly 5 to move to the top of the feeding conveyor belt 2, and then the longitudinal motion module 4 drives the transfer assembly 5 to move downward to the top of the feeding conveyor belt 2, and then the claw cylinder 53 drives the air claw clamp 54 to close and clamp the spring, and then the longitudinal motion module 4 drives the transfer assembly 5 to move upward away from the feeding conveyor belt 2, and the lateral motion module 3 drives the transfer assembly 5 to move to the guide rail 62, and then the longitudinal motion module drives the transfer assembly 5 to move to the top of the guide rail 62, at this time the claw cylinder 53 drives the air claw clamp 54 to release the spring, so that the spring falls on the guide rail 62, and repeat the above operation to move the spring on the feeding conveyor belt 2 to the guide rail 62 and arrange it neatly. If the direction of the spring is wrong, the rotating motor 51 can be used to drive the claw cylinder 53 to rotate 180 degrees, and the direction of the spring can be changed before putting it on the guide rail 62.

[0033] Specifically, the material guide rail assembly 6 includes a material guide mounting frame 61, and the material guide mounting frame 61 is fixedly mounted on the surface of the workbench 1. A plurality of material guide rails 62 are arranged in parallel on the material guide mounting frame 61. The cross-section of the material guide rail 62 is an inverted "V" shaped structure, so that the spring placed on the material guide rail 62 can roll to the lowest point of the material guide rail 62, thereby achieving positioning. A strip hole 63 is opened at the bottom of the material guide rail 62, and the strip hole 63 allows the pushing rod 75 of the pushing assembly 7 to pass through, thereby pushing the spring to move.

[0034] Specifically, the pushing component 7 includes a pushing guide rail 71 fixedly installed at the bottom of the material guiding mounting frame 61. The pushing guide rail 71 is arranged in parallel with the material guiding track 62. A pushing slider 72 is slidably connected to the pushing guide rail 71. A pushing cylinder bracket 73 is fixedly connected to the surface of the pushing slider 72 by screws. A pushing cylinder 74 is fixedly connected to the pushing cylinder bracket 73. The output shaft of the pushing cylinder 74 is fixedly connected to a pushing rod 75 by bolts. The number of the pushing rods 75 is the same as and corresponds one by one to the number of the material guiding tracks 62. The top end of the pushing rod 75 can penetrate through the strip-shaped hole 63. A pushing cylinder 76 is fixedly connected to the side surface of the material guiding mounting frame 61 by screws. The output shaft of the pushing cylinder 76 is fixedly connected to the pushing cylinder bracket 73. After the spring is transferred to the material guiding track 62, the pushing rod 75 is driven by the pushing cylinder 74 to pass through the strip-shaped hole 63 and extend onto the material guiding track 62. Then, the pushing cylinder bracket 73 is driven to move by the pushing cylinder 76, driving the pushing rod 75 to move. The pushing rod 75 pushes the spring to move towards the material receiving and flipping component 8. Until the spring is pushed into the material receiving and flipping component 8, the pushing cylinder 74 drives the pushing rod 75 to withdraw from the strip-shaped hole 63, and then returns to the initial position by driving of the pushing cylinder 76, waiting for the next material pushing.

[0035] Specifically, the material receiving and flipping component 8 includes a flipping bracket 81 fixedly connected to the surface of the workbench 1 by bolts. A flipping shaft 82 is rotatably connected to the surface of the flipping bracket 81 through a bearing seat. A plurality of positioning shafts 83 are welded or integrally formed on the side surface of the flipping shaft 82. The number of the positioning shafts 83 is the same as and corresponds one by one to the number of the material guiding tracks 62. A flipping motor 84 is fixedly connected to the side surface of the flipping bracket 81. The output shaft of the flipping motor 84 is in transmission connection with the flipping shaft 82. The spring is inserted into the positioning shaft 83 through pushing. Then, the flipping shaft 82 is driven to rotate 90 degrees by the flipping motor 84 to make the spring stand up. Then, the robot 9 takes away the standing spring and places it in a tray for the next step of processing, completing the overall loading operation.

[0036] Specifically, a manipulator is fixedly connected to the output end of the transfer robot 9. The manipulator includes a fixture bracket 91. A plurality of fixture cylinders 92 are fixedly connected to the fixture bracket 91. The number of the fixture cylinders 92 is the same as that of the positioning shafts 83. A clamping plate 93 is fixedly connected to the output shaft of the fixture cylinder 92. In this embodiment, the transfer robot 9 is a multi-axis mobile robot 9 in the prior art, which can drive the manipulator to move above the material receiving and flipping assembly 8 and the material receiving position of the downstream processing equipment. After the transfer robot 9 drives the manipulator to move above the flipping assembly, the fixture cylinder 92 is used to drive the clamping plate 93 to close and clamp the spring. Then, the transfer robot 9 moves the spring to the downstream equipment. This device has two feeding mechanisms, and the transfer robot 9 alternately clamps the springs conveyed by the two feeding mechanisms.

[0037] In one embodiment, a discharge cylinder mounting seat 22 is fixedly connected to the side surface of the end of the feeding conveyor belt 2 by bolts. A discharge cylinder 21 is fixedly connected to the discharge cylinder mounting seat 22. A discharge limit plate 23 is fixedly connected to the output shaft of the discharge cylinder 21 by bolts. The discharge limit plate 23 is arranged above the feeding conveyor belt 2. A discharge hopper 24 is arranged at the bottom of the end of the feeding conveyor belt 2. A discharge port is arranged on the workbench 1 below the discharge hopper 24. A discharge channel is fixedly connected to the inner side of the discharge port. After the spring is fed onto the feeding conveyor belt 2 through the vibrating feeding tray and transported to the end of the feeding conveyor belt 2 by the feeding conveyor belt 2, at this time, the discharge limit plate 23 blocks the spring from moving forward and waits for the transfer assembly 5 to pick up the spring.

[0038] Further, a position sensor 25 is fixedly connected to the side surface of the discharge limit plate 23. The detection end of the position sensor 25 penetrates through the discharge limit plate 23. The position sensor 25 is used to detect whether the spring is in place. After the spring is in place, a signal is sent to the controller, and the controller sends an instruction to the transfer assembly 5 to work.

[0039] Furthermore, a camera support 26 is fixedly connected to the side of the workbench 1 located on the feeding conveyor belt 2, and a camera 27 is fixedly connected to the camera support 26. The orientation of the spring is visually recognized by the camera 27, as well as whether there are springs tangled together. If it is recognized that the orientation of the spring is incorrect (one end of the spring is larger and the other is smaller, and normally the larger end needs to be in the front), a signal is sent to the PLC controller, and the PLC controller sends a signal to the transfer assembly 5. During the transfer process, the transfer assembly 5 drives the gripper cylinder 53 to rotate 180 degrees through the rotation motor 51, so that the spring rotates 180 degrees to adjust the direction of the spring. If the camera 27 recognizes that the springs are tangled together, at this time, the discharging cylinder 21 drives the discharging limit plate 23 to move upward to release the limit on the spring, and the spring continues to move forward along the feeding conveyor belt 2 and falls into the discharging hopper 24, and then rolls along the discharging hopper 24 into the discharging channel for discharging.

[0040] Furthermore, a material blocking cylinder 64 is fixedly connected to the side of the material guiding mounting frame 61 by bolts, an output shaft of the material blocking cylinder 64 is fixedly connected to a material blocking mounting bracket 65 by bolts, a plurality of material blocking plates 66 are fixedly connected to the material blocking mounting bracket 65 by bolts, the material blocking plates 66 are arranged above the material guiding track 62, and the number of the material blocking plates 66 is the same as and corresponds to the number of the material guiding tracks 62 one by one. At the beginning, the material blocking plates 66 extend into the material guiding track 62 to block the springs from moving. After all the springs are placed in the material guiding tracks 62, the material blocking cylinder 64 drives the material blocking mounting bracket 65 to move upward, so that the material blocking plates 66 leave the material guiding track 62. At this time, the springs can be pushed onto the receiving and flipping assembly 8 by the pushing assembly 7 for flipping.

[0041] Working principle of the utility model: The spring is fed onto the feeding conveyor belt 2 through the vibrating feeding tray. The spring moves to the end of the feeding conveyor belt 2 along the feeding conveyor belt 2. The spring is blocked by the discharging limiting plate 23 and stops advancing. At this time, the direction of the spring is visually recognized by the camera 27. If the direction is correct, the transverse movement module 3 drives the transfer assembly 5 to move above the feeding conveyor belt 2. Then, the longitudinal movement module 4 drives the transfer assembly 5 to move downward to above the feeding conveyor belt 2. Then, the clamping jaw cylinder 53 drives the jaw clamping block 54 to close and clamp the spring. After that, the longitudinal movement module 4 drives the transfer assembly 5 to move upward away from the feeding conveyor belt 2. The transverse movement module 3 drives the transfer assembly 5 to move onto the guiding track 62. Then, the longitudinal movement module drives the transfer assembly 5 to move above the guiding track 62. At this time, the clamping jaw cylinder 53 drives the jaw clamping block 54 to release the spring, and the spring falls onto the guiding track 62. If it is detected that the direction of the spring is incorrect, during the transfer process, the rotary cylinder drives the spring to rotate 180 degrees to ensure that the large-end of the spring is aligned with the positioning shaft 83. After the transfer assembly 5 transfers the spring to the guiding track 62, the pushing cylinder 74 drives the pushing rod 75 to pass through the strip-shaped hole 63 and extend onto the guiding track 62. Then, the pushing cylinder 76 drives the pushing cylinder bracket 73 to move, driving the pushing rod 75 to move. The pushing rod 75 pushes the spring towards the direction of the receiving and flipping assembly 8 until the spring is pushed into the receiving and flipping assembly 8. Then, the pushing cylinder 74 drives the pushing rod 75 to withdraw from the strip-shaped hole 63. Then, the pushing cylinder 76 drives it to return to the initial position and wait for the next pushing. The spring is pushed and inserted into the positioning shaft 83. Then, the flipping motor 84 drives the flipping shaft 82 to rotate 90 degrees to make the spring stand up. Then, the robot 9 picks up the standing spring and places it into the tray for the next step of processing, completing the overall feeding operation. In this embodiment, there are a total of two feeding mechanisms, and the transfer robot 9 takes springs from the two feeding mechanisms in turn to improve the feeding efficiency.
