[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] Schematic diagram; Figure 3 This is a structural schematic diagram of the conveyor table, part B of this utility model; Figure 4 This is a schematic diagram of the carrier plate moving stage of this utility model.

[0025] As attached Figure 1 As shown, an automatic handle assembly machine includes a fixture 1, a fixture transfer mechanism 2, a part A conveyor 3, a part A positioning mechanism 4, a part A transfer mechanism 5, a part B conveyor 6, a handle transfer mechanism 1 7, a screw driver 8, a tray moving platform 9, and a handle transfer mechanism 2 10. Several fixtures 1 are installed on the fixture transfer mechanism 2. The handle transfer mechanism 1 7, the screw driver 8, and the handle transfer mechanism 2 10 are distributed around the fixture transfer mechanism 2. The part A conveyor 3 is located on one side of the part B conveyor 6. The part A positioning mechanism 4 is located at the discharge end of the part A conveyor 3. The part A transfer mechanism 5 is located above the part A positioning mechanism 4. The handle transfer mechanism 1 7 is located above the part B conveyor 6, and the tray moving platform 9 is located below the handle transfer mechanism 2 10.

[0026] The fixture transfer mechanism 2 includes a cam divider and a disk. The output shaft of the cam divider is fixed at the center of the disk, and the fixture 1 is fixed on the disk.

[0027] The cam divider drives the disc to rotate, which can rotate the jig 1 with the loading handle to different processing positions.

[0028] The conveyor platform 3 for part A is a belt conveyor.

[0029] As attached Figure 2 As shown, the positioning mechanism 4 for part A includes a positioning platform 41, a positioning plate 42, a positioning plate horizontal movement cylinder 43, a lifting cylinder 44, and a lifting block 45. The positioning platform 41 has a through hole for the lifting block 45 to pass through. The lifting cylinder 44 is located below the positioning platform 41, and the lifting block 45 is fixed to the piston rod of the lifting cylinder 44. The positioning platform 41 is equipped with positioning plate horizontal movement cylinders 43 on its left and right sides, and the positioning plate 42 is fixed to the piston rod of the positioning plate horizontal movement cylinder 43. The positioning platform 41 has a positioning groove, and the front end of the positioning groove has an opening for part A to pass through.

[0030] After a part A is horizontally conveyed by the part A conveyor 3 into the positioning slot of the positioning table 41, the two positioning plate horizontal movement cylinders 43 drive the positioning plates 42 to move towards part A, thereby positioning part A in the center position. The multi-axis robot arm of the part A transfer mechanism 5 drives the positioning pin to move and align it with the through hole of part A. Then, the positioning pin lifting cylinder 11 drives the positioning pin to move down until the positioning pin passes through the through hole of part A and inserts into the groove on the top of the lifting block 45. Then, the lifting cylinder 44 drives the lifting block 45 to move up, and at the same time, the positioning pin moves up, so that part A can be lifted out of the positioning table 41 and finally held by the gripper.

[0031] The part A transfer mechanism 5 includes a multi-axis manipulator and a gripper. The multi-axis manipulator is equipped with a gripper and a positioning pin lifting cylinder 11. The piston rod end of the positioning pin lifting cylinder 11 is fixed with a positioning pin, and the end of the lifting block 45 is provided with a groove for inserting the positioning pin.

[0032] As attached Figure 3 As shown, the part B conveyor 6 includes a platform body 61, an X-axis horizontal drive cylinder 62, a Y-axis horizontal drive cylinder 63, a push plate 64, a pressure block 65, and a pressure block lifting cylinder 66. The cylinder bodies of the X-axis horizontal drive cylinder 62 and the Y-axis horizontal drive cylinder 63 are fixed to the front and rear ends of the platform body 61, respectively. Push plates 64 are fixed to the piston rods of both the X-axis and Y-axis horizontal drive cylinders 62 and 63. The piston rods of the X-axis and Y-axis horizontal drive cylinders 62 and 63 are perpendicular to each other in the horizontal plane. The platform body 61 has four straight flow channels that connect end to end, with adjacent straight flow channels perpendicular to each other. A pressure block lifting cylinder 66 is located above the platform body 61, and a pressure block 65 is fixed to the piston rod of the pressure block lifting cylinder 66. The four straight flow channels that connect end to end form a rectangular flow channel.

[0033] Several parts B are placed inside a rectangular flow channel, leaving a space equal to the length of part B within the channel. Then, the piston rod of the X-axis horizontal drive cylinder 62 moves the push plate 64 on it, pushing a row of parts B along the X-axis straight flow channel a distance equal to the length of part B. Next, the piston rod of the Y-axis horizontal drive cylinder 63 moves the push plate 64 on it, pushing another row of parts B along the Y-axis straight flow channel a distance equal to the length of part B. Repeating these steps allows the parts to move along the rectangular flow channel.

[0034] The pressing block lifting cylinder 66 can drive the pressing block 65 to move down, and the pressing block 65 will press the parts A and B placed together below together.

[0035] Both handle transfer mechanism 17 and handle transfer mechanism 210 consist of a multi-axis manipulator and grippers, with grippers installed on the multi-axis manipulator.

[0036] As attached Figure 4 As shown, the tray moving stage 9 includes a base 91, a horizontal linear module 92, and a slide plate 93. The horizontal linear module 92 is mounted on the base 91, and the slide block of the horizontal linear module 92 is fixed to the bottom of the slide plate 93. The slide plate 93 is slidably connected to the horizontal straight rail on the base 91.

[0037] A carrier tray for loading the assembled handles is placed on the slide plate 93. Once the carrier tray is full, the horizontal linear module 92 drives the slide plate 93 to move horizontally with the carrier tray to the tray retrieval position.

[0038] The working method of this application is as follows: Several parts A are placed on the parts A conveyor 3 and moved horizontally in sequence. Several parts B are placed in the rectangular flow channel of the parts B conveyor 6 for conveying. When part A is conveyed into the parts A conveyor 3 and positioned at the accurate pick-up position, the parts A transfer mechanism 5 picks up the part and places it on the parts B. The pressure block 65 is driven down by the pressure block lifting cylinder 66 to press parts A and parts B together to form a complete handle. Then, the parts B conveyor 6 moves the assembled handle to the pick-up position, and the handle transfer mechanism 7 transports the handle into the fixture 1.

[0039] The fixture transfer mechanism 2 drives the fixture 1 with the handle to move below the screw-driving machine 8, where the screw-driving machine 8 screws the handle in. Then, the fixture transfer mechanism 2 drives the finished handle to move below the handle transfer mechanism 2 10. Finally, the handle transfer mechanism 2 10, in conjunction with the tray moving table 9, places the handle in the fixture 1 into the tray and moves the tray to the tray removal position to remove it.
