[0040] A blanking component 4, the blanking component 4 is arranged on the frame 1, and is used to remove the assembled utility knife from the turntable 3, with a higher automation coverage rate.

[0041] The feeding unit 2 includes a handle lifter 21 arranged on the side of the frame 1. A detection rotating table 22 is arranged on the top of the frame 1. The detection rotating table 22 rotates the handle transmitted by the handle lifter 21 to a suitable position. A grasping detection table 25 is arranged on the top of the frame 1. The detection rotating table 22 can detect the handle lifted to the top by the handle lifter 21, and then rotate it to a suitable position after detection.

[0042] A slide rail base 27 is arranged on the top of the frame 1. A lifting pneumatic component 29 is movably arranged on the side of the slide rail base 27. A motor 1 23 for driving the lifting pneumatic component 29 to slide on the slide rail base 27 is arranged on the side of the slide rail base 27. A chain-type protective shell 24 for protecting the circuit of the lifting pneumatic component 29 is arranged on the slide rail base 27. A triangular plate 28 is movably arranged on the side of the lifting pneumatic component 29. Three suction cup grasping components 26 are arranged on the surface of the triangular plate 28. The grasping detection table 25 can perform a secondary detection on the handle, clamp it after completion, and then place it on the disc.

[0043] Three suction cup grippers 26 move from the tool shank lifter 21 to the turntable 3, and are respectively used to grab the tool shanks on the tool shank lifter 21 onto the detection rotary table 22, synchronously grab the tool shanks on the detection rotary table 22 onto the grasping detection table 25, and move the tool shanks on the grasping detection table 25 to the top of the turntable 3. A clamping and assembling component 8 for rotating the tool shank to the required assembling position is arranged on the turntable 3. Through the setting of the triangular plate 28, multiple grippings can be completed at one time.

[0044] The clamping and assembling component 8 includes a CKD motor rotating table 85 arranged between the bottom of the turntable 3 and the frame 1. The CKD motor rotating table 85 is used to accurately rotate the turntable 3 to the position where various components need to be assembled. A plurality of clamping tables 81 for placing tool shanks are arranged on the top of the turntable 3. A pushing cylinder 82 is arranged on the top of the frame 1, an attitude control part 83 is arranged on the top of the frame 1, and two anti-disengagement plates 84 are arranged on the top of the turntable 3.

The anti-disengagement plates 84 are arranged on the top of the two, and can prevent the tool shank from disengaging from the clamping table 81 during use when the force is too strong.

[0045] The blade feeding and assembling component 7 includes support legs 71 arranged on the frame 1. A blade conveyor belt 72 is arranged on the top of the support legs 71 for conveying the blades to the designated position. A transverse rail sliding table 73 is arranged on the top of the support legs 71. A pneumatic lifting table board 75 is movably arranged on the side of the transverse rail sliding table 73. A pneumatic clamping gripper 74 for clamping the blade is arranged at the bottom of the pneumatic lifting table board 75. A blade clamping detection head 76 is arranged on the side of the pneumatic lifting table board 75 for detecting the attitude of the blades on the blade conveyor belt 72, calculating the clamping position and rotation angle of the pneumatic clamping gripper 74. A push block feeding and assembling component 5 for assembling the utility knife is arranged on the frame 1. The position where the pneumatic clamping gripper 74 clamps the blade is made of a soft anti-cutting material, and the transverse rail sliding table 73 can accurately position to the position where the blade needs to be clamped and move the pneumatic clamping gripper 74 to the top of the blade.

[0046] The pusher feeding and assembling component 5 includes a lead screw track table 52 arranged on the frame 1. On the side of the lead screw track table 52, there is a second motor 53 for driving the lead screw track table 52. On the side of the lead screw track table 52, there is a lifting and sliding table 54. At the bottom of the lifting and sliding table 54, there is a manipulator 55. At the top of the lead screw track table 52, there is a pusher detection table 56. On the side of the frame 1, there is a pusher vibration disk 51, which is used to transfer the pushers to be assembled to the pusher detection table 56 for detection. On the top of the frame 1, there is a rear top block feeding and assembling component 6 for assembling the rear top block of the utility knife. The lead screw track table 52 can horizontally move the lifting and sliding table 54. The lifting and sliding table 54 can control the manipulator 55 to pick up the pusher from the pusher detection table 56, install it on the knife handle, and connect it to the blade.

[0047] The rear top block feeding and assembling component 6 includes a support table 62 arranged on the frame 1. At the top of the support table 62, there is a rear top block placement table 66. On the side of the frame 1, there is a rear top block vibration disk 61, which is used to transfer the internal rear top blocks to the rear top block placement table 66. At the top of the support table 62, there is an attitude control cylinder 64. At the top of the support table 62, there is a parallel rail table 65. On the side plate of the pusher detection table 56, there is a pneumatic clamping pliers 63. The parallel rail table 65 and the pneumatic clamping pliers 63 are used to assemble the rear top block to the knife handle. The parallel rail is used to drive the pneumatic clamping pliers 63 to move to the rear top block, and then the pneumatic clamping pliers 63 are controlled pneumatically to assemble the rear top block to the knife handle.

[0048] The blanking component 4 includes a blanking conveyor belt 41 arranged on the frame 1. On the top of the frame 1, there is a transverse rail table 42. At the top of the transverse rail table 42, there is a pneumatic clamping mechanical claw 43. The transverse rail table 42 and the pneumatic clamping mechanical claw 43 are used to pick up the assembled utility knife inside the clamping table 81 and transfer it to the packaging place through the blanking conveyor belt 41. The transverse rail table 42 moves the pneumatic clamping mechanical claw 43 to the position where the assembled utility knife needs to be removed, and finally places it on the blanking conveyor belt 41 for the next process.

[0049] By placing the handle of the utility knife to be assembled inside the handle lifter 21, the handle lifter 21 can work at this time to sequentially and orderly convey the handles to the top. At this time, the first motor 23 will drive the lifting pneumatic component 29 to move through the slide rail pedestal 27, and the lifting pneumatic component 29 will drive the suction cup gripper 26 and the triangular plate 28 to move, suck the handle at the top of the handle lifter 21, and move it to the top of the detection rotating table 22. It is detected that it is not placed in accordance with the designed shape. At this time, the detection rotating table 22 is started to rotate the handle to a suitable angle, and then the handle on the detection rotating table 22 is moved to the grasping and detecting table 25 through the suction cup gripper 26 in the middle part of the triangular plate 28. Then, the handle on the grasping and detecting table 25 is placed into the clamping table 81 through the suction cup gripper 26 close to the turntable 3. At this time, the pushing cylinder 82 and the attitude control component 83 work sequentially to adjust the attitude of the handle placed inside the clamping table 81 so that it can be accurately installed inside the clamping table 81. Then, the turntable 3 will rotate driven by the CKD motor rotating table 85 to install the blade.

[0050] Before rotating the handle inside the clamping table 81 to the position where the blade needs to be installed, the blade will move to the transverse rail sliding table 73 through the blade conveyor belt 72 at this time. The transverse rail sliding table 73 will drive the pneumatic lifting table board 75 to move to the top of the blade. The blade clamping detection head 76 detects the attitude of the blade, calculates the position where the pneumatic lifting table board 75 needs to descend, and then uses the pneumatic clamping gripper 74 to clamp the blade. At this time, the handle that just needs to install the blade moves here through the clamping table 81, and the pneumatic clamping gripper 74 installs the blade on the handle, and then will perform the next installation under the action of the CKD motor rotating table 85.

[0051] Move the handle with the blade installed to the lead screw rail table 52. At this time, before installation, the push block to be installed is placed inside the push block vibrating disk 51. The push block will move to the lead screw rail table 52 under the vibration and spiral action of the push block vibrating disk 51. The lead screw rail table 52 moves the lifting sliding table 54 to the top of the push block. At this time, the lifting sliding table 54 drives the manipulator 55 to clamp the push block, and then rotates to the suitable installation position to install the push block on the handle and connect it to the blade, so that the blade can be pushed out by pushing the push block. At this time, the CKD motor rotating table 85 will drive the turntable 3 to rotate again to move the handle with the installed blade and push block to the support table 62.

[0052] At this time, the knife handle is carried by the clamping table 81 to the support table 62. Then, the top block will be poured into the vibrating disk 61 of the rear top block. Through the vibration and rotation of the vibrating disk 61 of the rear top block, the rear top block is moved to the support table 62, and then conveyed to the placement table 66 of the rear top block. The attitude of the rear top block is adjusted by the attitude control cylinder 64. Then, the parallel slide rail table 65 drives the pneumatic clamping pliers 63 to move to the rear top block on the placement table 66 of the rear top block. The rear top block is installed on the knife handle through the pneumatic clamping pliers 63, completing the assembly of the entire utility knife. At this time, the CKD motor rotating table 85 will drive the assembled utility knife to rotate again, rotating it to the blanking conveyor belt 41. Through the sliding of the horizontal slide rail table 42, the pneumatic clamping mechanical claw 43 is moved to the assembled utility knife. Then, the pneumatic clamping mechanical claw 43 conveys the utility knife to the blanking conveyor belt 41 for the next step of work.

[0053] Embodiment 2: The main structure of Embodiment 2 is the same as that of Embodiment 1. The difference is that a protective cover is provided on the top of the frame 1 in Embodiment 2. The protective cover provided on the frame 1 can prevent debris generated when the internal structure is damaged from damaging external objects.
