In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. The present invention is further described in detail below in conjunction with the accompanying drawings.

[0031] like Figure 1-7 As shown, a barbecue tongs continuous rod feeding mechanism proposed by the present invention comprises a workbench 1, two sets of fixed brackets 2 are installed on the workbench 1, a product fixed mold bar 3 is horizontally fixed on the fixed bracket 2, movable and liftable product lifting mold bars 4 are installed on both sides of the product fixed mold bar 3, the product fixed mold bar 3 and the product lifting mold bar 4 are fixedly connected by a mold bar mounting aluminum profile 5, a material pressing limit mechanism 6 is arranged on the top of the fixed bracket 2, and the material pressing limit mechanism 6 is located above the product fixed mold bar 3 and the product lifting mold bar 4, and a transverse proximity switch 26 is also arranged on the workbench 1 to determine the initial position of the coordinate system;

[0032] The workbench 1 is also provided with a transverse slide rail 7, on which a mobile support frame 8 is slidably provided, on which a lifting mechanism 9 is provided, and on which a lifting detection device 27 is provided to detect lifting. The lifting mechanism 9 is fixedly connected to the bottom of the product lifting mold bar 4, and a transverse mechanism 10 is also provided on one side of the mobile support frame 8. The lifting mechanism 9 and the transverse mechanism 10 jointly drive the product lifting mold bar 4 to lift and move transversely, and the material rod is limited under the action of the material pressing limiting mechanism 6, thereby realizing automatic feeding;

[0033] like Figure 2 As shown, position grooves 11 are evenly distributed on the product fixing mold bar 3, and pushing grooves 12 are evenly distributed on the product lifting mold bar 4. The position grooves 11 and the pushing grooves 12 are aligned and are used to place and push the material rods.

[0034] like Figure 1-4 As shown, the pressing material limiting mechanism 6 includes a mounting block 13, a pressing material optical axis 14 and a pressing material spring 15. A circular limiting groove 16 is provided on the top of the fixed bracket 2. A limiting push rod 17 is passed through the limiting groove 16. The mounting block 13 is fixed to the bottom of the limiting push rod 17. Two sets of parallel pressing material optical axes 14 are fixed on the mounting block 13. The pressing material optical axes 14 are located above the product fixing mold bar 3 and the product lifting mold bar 4. The pressing material spring 15 is sleeved on the outer end of the limiting push rod 17 and fixed It is fixed on the top of the fixed bracket 2, and the other end is fixed on the top surface of the mounting block 13. A circular limiting top plate 28 is fixed on the top of the limiting top plate 28. The diameter of the limiting top plate 28 is larger than the limiting top rod 17 and smaller than the diameter of the connection between the bottom of the limiting groove 16 and the fixed bracket 2. The limiting top plate 28 is limited in the limiting groove 16, thereby limiting the limiting top rod 17, and then limiting the mounting block 13 and the pressing optical axis 14 in the vertical direction, so that the pressing optical axis 14 can only move up and down.

[0035] like Figure 5 , 6 As shown, the transverse movement mechanism 10 includes a transverse movement servo motor 18, a transverse movement lead screw 19 and a lead screw sleeve block 20. A support shell 21 is installed on the top of the workbench 1 and one side of the movable support frame 8. An end block 22 is fixed to the bottom of the support shell 21. The transverse movement servo motor 18 is installed on the outer surface of the support shell 21. One end of the transverse movement lead screw 19 is fixedly connected to the output end of the transverse movement servo motor 18, and the other end of the transverse movement lead screw 19 is rotatably arranged on the end block 22. The lead screw sleeve block 20 is threadedly sleeved on the transverse movement lead screw 19, and one side of the lead screw sleeve block 20 is fixedly connected to the outer surface of the movable support frame 8. The transverse movement servo motor 18 drives the transverse movement lead screw 19 to rotate, and the transverse movement lead screw 19 drives the lead screw sleeve block 20 and the movable support frame 8 to move. The movable support frame 8 moves relative to the transverse movement slide rail 7, thereby driving the lifting mechanism 9 and the product lifting mold bar 4 to move as a whole.

[0036] like Figure 6 , 7As shown in , 8, the lifting mechanism 9 includes a lift 23 and a lifting base plate 24. The lifting base plate 24 is fixed on the outer side of the mold bar mounting aluminum profile 5. The bottom of the lift 23 is fixed to the bottom of the mobile support frame 8. The top of the lift 23 and the bottom of the lifting base plate 24 are fixedly connected. The lift 23 drives the lifting base plate 24 and the product lifting mold bar 4 to move up and down. The lift 23 is driven by a lifting servo motor 29 to convert the rotational motion of the lifting servo motor 29 into linear motion. The mobile support frame 8 and the lifting base plate 24 have a uniform U-shaped structure. A lifting slider 25 is fixed on the outer side of the lifting base plate 24. The lifting slider 25 is slidably arranged on the inner side of the mobile support frame 8, so that the support base plate drives the product lifting mold bar 4 to move up and down relative to the mobile support frame 8.

[0037] When in use, the product slides from the material channel into the position slot 11 and the push slot 12 of the first position. At this time, the lifting servo motor 29 drives the lift 23 to rise. The specific principle is the existing technology and will not be described in detail here. The lift 23 drives the lifting bottom plate 24 and the product lifting mold bar 4 to rise. As the lift 23 rises, the product is driven to rise synchronously. At the same time, the product abuts against the bottom of the pressing optical axis 14, pushing the pressing optical axis 14 to rise, and the pressing spring 15 is squeezed.

[0038] The lifting detection device 27 monitors the rising position of the lift 23 in real time. The lifting detection device 27 is an encoder structure, which can accurately determine the rising position and input the position information into the PLC. The PLC analyzes and processes the input position information according to the pre-set program and algorithm, determines the current accurate position of the product, and then gives the next step action instruction according to the established production logic;

[0039] When the PLC confirms that the product has reached the predetermined precise position, the transverse servo motor 18 starts to work, the transverse servo motor 18 drives the transverse screw 19 to rotate, the transverse screw 19 drives the screw sleeve 20 and the mobile support frame 8 to move, and the mobile support frame 8 moves relative to the transverse slide rail 7, thereby driving the lifting mechanism 9 and the product lifting mold bar 4 to move as a whole, accurately moving the product to the specified position, which position corresponds to the second position slot 11 of the product fixed mold bar 3. After reaching the specified position, the lifting servo motor 29 starts again, driving the elevator 23 to descend, so as to place the product steadily in the second position slot 11 of the product fixed mold bar 3. At this time, the pressing optical axis 14 will press the product under the action of the pressing spring 15 to ensure that it will not be displaced during subsequent processing. After completing the placement action, the transverse motor returns to the origin according to the program setting. At this time, the product is located in the second position slot 11 and the second push slot 12, ready to meet the feeding process of the next product;

[0040] When the moving support frame 8 returns to the origin, the transverse proximity switch 26 detects in real time whether it has returned to the origin position accurately. When the position is confirmed to be correct, the next product slides into the first position in the product fixing mold bar 3, and the entire feeding mechanism starts to repeat the above steps again, and the cycle is repeated. The barbecue tongs production process realizes the fully automatic and continuous production of workpieces in five processes from bending round bars to flattening, punching, rotating 90 degrees to flatten and trimming, and welding clips. There is no need for manual separation operations, which greatly improves production efficiency and product quality, reduces production costs and labor intensity, and has broad market application prospects.

[0041] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
