Description

Technical Field

[0001] The invention belongs to the field of welding wire production, and in particular relates to an online upright positioning and placing device for a welding wire shaft. Background Art

[0002] A wire spool (also called a wire reel) consists of two circular discs connected by a winding drum. After the wire is drawn, it is wound onto the spool. After production is complete, the spool is moved from the production line to a storage rack. Currently, the transfer of wire reels is mostly accomplished using an electric hoist. The process involves placing the wire spool upright on a conveyor line, manually manipulating the hoist to the spool position, and then manually placing a lifting rope through the center hole of the spool. Finally, the hoist is used to lift and transfer the wire spool.

[0003] With the rapid development of automation technology, it has become an inevitable development trend for robots to automatically grab the welding wire shaft and move it. The robot operation places high requirements on the accuracy of the welding wire shaft discharge position, while the electric hoist lifting and transfer method has very low requirements on the accuracy of the welding wire shaft position. The welding wire shaft position accuracy is far from meeting the robot grasping position accuracy requirements. Therefore, how to determine the wire shaft position to ensure accurate grasping by the robot has become a problem that needs to be solved urgently by technical personnel in this field. Summary of the Invention

[0004] In view of this, the present invention aims to provide an online upright positioning and placement device for the welding wire shaft, so as to position and place the welding wire shaft upright, so as to facilitate the robot to grasp it quickly and accurately.

[0005] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0006] A device for online upright positioning and placement of a welding wire shaft comprises a lifting frame, a first baffle and two support rails. The two support rails are arranged at the terminal ends of a slide and are used to receive the welding wire shaft from the slide. Two protective bars are symmetrically provided on the outer sides of the two support rails. The distance between the two protective bars is the same as the outer width of the welding wire shaft. The lifting frame is arranged between the two support rails and is located below the support surface of the support rails. The first baffle is arranged above the support rails and is located in front of the lifting frame.

[0007] Furthermore, the lifting frame includes a fixed plate fixed relative to the support rail position, the fixed plate is provided with a pushing element, the push rod of the pushing element is vertically upward and is provided with a support block, the top surface of the support block is a concave arc surface structure corresponding to the welding wire shaft.

[0008] Furthermore, two lifting racks are arranged side by side along the conveying direction of the support track, and the distance between the two lifting racks is greater than the diameter of the welding wire shaft, wherein the rear end of the support block of the front lifting rack is connected and fixed with a second baffle.

[0009] Furthermore, a guide column is vertically connected and fixed to the bottom end of the support block downward, and the fixing plate is provided with a guide hole corresponding to the guide column, and the guide column passes through the guide hole.

[0010] Furthermore, the vertical distance between the protective rod and the support track is smaller than the radius of the welding wire shaft disk.

[0011] Furthermore, the distance between the two support rails is the same as the distance between the two discs of the welding wire shaft.

[0012] Furthermore, a blocking cylinder corresponding to the slideway is provided at the starting end of the support track.

[0013] Compared with the prior art, the device for online upright positioning and placement of welding wire shafts described in the present invention has the following advantages:

[0014] (1) In the present invention, the welding wire shaft is lifted and supported from the slideway by a lifting frame, and then the welding wire shaft is positioned upright online to ensure smooth grasping by the robot arm.

[0015] (2) In the present invention, the provision of two lifting frames enables positioning of two welding wire shafts at one time, and then moving the two welding wire shafts at one time, thereby meeting the high-yield production requirements of welding wire.

[0016] (3) In the present invention, the second baffle on the front lifting frame prevents the welding wire shaft on the front lifting frame from contacting and colliding with the welding wire shaft that subsequently rolls down the slide, thereby avoiding damage to the welding wire shaft.

[0027] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0028] A device for online upright positioning of welding wire shafts, Figure 1As shown, the device comprises a lifting frame 6, a first baffle 5, and two horizontal, side-by-side support rails 1. The two support rails 1 are located at the ends of an inclined, slideway 7, which is higher than the support rails 1. The distance between the two support rails 1 is the same as the distance between the two circular discs of the welding wire shaft 9. The welding wire shaft 9 automatically rolls or slides onto the two support rails 1 along the slideway 7. At this time, the welding wire shaft 9 is in an upright position (with its central axis and center hole horizontal, facilitating hooking or insertion by a three-axis manipulator). Its two circular discs are tightly attached to the two support rails 1, and the welding wire shaft 9 rolls forward on the support rails 1 by inertia. Two protective bars 2 are symmetrically arranged on the outside of the two support rails 1. The distance between the two protective bars 2 is the same as the outer width of the welding wire shaft 9 (i.e., the distance between the two discs). The protective bars 2 protect the welding wire shaft 9 and prevent it from falling off the support rails 1. Preferably, the vertical distance between the protective bars 2 and the support rails 1 is less than the radius of the welding wire shaft 9 disc, so that the three-axis manipulator can insert the welding wire shaft 9 into its center hole. The lifting frame 6 is arranged between the two support rails 1 and below the support surface of the support rails 1. The first baffle 5 is arranged above the support rails 1 and in front of the lifting frame 6. In this embodiment, the front and rear directions are relative to the moving direction of the welding wire shaft.

[0029] In this embodiment, the support frame 6 includes a fixed plate 63 fixed relative to the support rail 1. The fixed plate 63 is provided with a pushing element 64, which is a pneumatic, hydraulic, or electric cylinder, preferably a pneumatic cylinder. The push rod of the pushing element 64 is vertically upward and is provided with a mounting seat 62. A support block 61 is mounted on the mounting seat 62. The top surface of the support block 61 is a concave arc structure corresponding to the welding wire shaft 9.

[0030] In order to prevent the welding wire shaft on the slide 7 from sliding down and colliding with the welding wire shaft that had previously slid onto the support rail 1 during the positioning process of the welding wire shaft on the support rail 1, a blocking cylinder 8 corresponding to the slide 7 is provided at the starting end of the support rail 1. The blocking cylinder 8 is also called a stop cylinder, which can stop the welding wire shaft on the slide, that is, prevent the welding wire shaft on the slide from continuing to move. After the positioning of the welding wire shaft 9 on the support rail 1 is completed, the blocking cylinder 8 stops the blocking function, and the welding wire shaft on the slide falls onto the support rail 1. The structure and principle of the blocking cylinder 8 are existing technologies and will not be described in detail here.

[0031] In the production of welding wire, multiple production lines are simultaneously drawing wires, so the output and yield of welding wire per unit time are relatively high. The manipulator needs to grab and move at least two welding wire shafts each time to meet the production capacity requirements. The welding wire shafts produced by multiple production lines are all transported and moved by the slide 7. Therefore, in this embodiment, two lifting frames 6 are arranged side by side and adjacent to each other along the conveying direction of the support rail 1. The distance between the two lifting frames 6 is greater than the diameter of the welding wire shaft 9. The two lifting frames 6 each lift a welding wire shaft to position and arrange the two welding wire shafts. The rear end of the mounting seat 62 of the lifting frame 6 located on the front side is connected and fixed with a second baffle 3. The second baffle 3 moves up and down with the mounting seat 62 and the support block 61. In the present invention, the first baffle 5 is used to prevent the first welding wire shaft of the two welding wire shafts 9 positioned each time from moving on the support rail 1, and the second baffle 3 prevents the second welding wire shaft of the two welding wire shafts 9 from moving on the support rail 1, preventing the two welding wire shafts 9 from contacting and colliding, thereby avoiding damage to the welding wire.

[0032] In order to improve the linearity of the vertical movement of the support block 61 and ensure its lifting position accuracy, a guide column 65 is fixed vertically downward to the bottom end of the support block 61. The fixing plate 63 is provided with a guide hole corresponding to the guide column 65, and the guide column 65 passes through the guide hole.

[0033] The process of arranging two upright wire shafts is as follows: the first wire shaft 9 from the slide 7 falls from the slide 7 onto the support track 1, and moves forward along the support track 1 until it moves to the position corresponding to the front lifting frame 6. The first baffle 5 blocks the first wire shaft, and the blocking cylinder 8 blocks the second wire shaft 9 to prevent it from sliding down the slide 7. Figure 1 As shown. The push rod of the pushing element 64 of the front lifting frame 6 is lifted, the second baffle 3 and the support block 61 move upward, and the support block 61 lifts the first welding wire shaft 9 to the set height, positioning the upright first welding wire shaft 9. Then, the blocking cylinder 8 stops the blocking operation, and the second welding wire shaft 9 slides down the slide 7 and moves forward along the support track 1 until it moves to the position above the rear lifting frame 6. The second welding wire shaft is blocked by the second baffle 3, as shown. Figure 2 As shown, the second baffle 3 can prevent the first and second welding wire shafts 9 from contacting and colliding, thereby preventing the welding wire from being damaged and ensuring the quality of the welding wire. At this time, the rear lifting frame 6 lifts the second welding wire shaft 9 to the same height as the first welding wire shaft for positioning, so that the two welding wire shafts 9 can be placed upright online. Figure 3 As shown, at this time, the two welding wire shafts 9 are arranged side by side, and the distance between the two welding wire shafts 9 is the same as the distance between the two insertion rods of the three-axis manipulator 11, so that the three-axis manipulator 11 can simultaneously grab and move the two welding wire shafts 9 and place the two welding wire shafts on the placement rack 10. In this way, multiple welding wire shafts can be neatly placed on the placement rack 10 in groups of two, as shown in FIG. Figure 4 shown.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
