Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to a multifunctional intelligent shockproof display stand welding mechanism. Background Art

[0002] The multifunctional intelligent shockproof display stand is a common display stand, which is usually provided with an intelligent panel on the top to display the displayed items, and the bottom end of the display stand is usually connected to the welding plate by welding through a cylindrical bracket, and the shockproof base can be installed at the lowest end for shockproof;

[0003] For example, the Chinese patent "A Metal Display Rack Production Process and Equipment Thereof" with publication number: CN112440110A includes a stamping mechanism for stamping, a welding mechanism for welding and fixing, and a polishing mechanism for polishing; wherein the welding mechanism includes a welding machine body and a workbench located on one side of the welding machine body, the welding machine body and a welding head are provided above the workbench, the workbench has a built-in groove on the side facing the welding head, a bearing frame for the metal display rack to be welded is provided inside the built-in groove, a longitudinal movement component for driving the bearing frame to move longitudinally is provided inside the built-in groove, and a transverse movement component for driving the bearing frame to move transversely is provided inside the built-in groove. The present application utilizes the longitudinal movement component and the transverse movement component to realize the multi-directional movement of the bearing frame, so that welding can be performed on different welding points of the product, replacing manual labor and improving welding accuracy.

[0004] In the process of welding the bracket, the welding of the cylindrical bracket usually requires the staff to perform welding in two steps. Because it is difficult for the staff to circle the inside of the display rack, usually after circling half a circle on the outside, half of the staff's body enters the inside of the display rack to weld the other half circle. Therefore, when welding the display rack, it will lead to low welding efficiency and more troublesome welding. Alternatively, there are also some welding mechanisms as shown in the above-mentioned patents, which can be separated from the staff for welding operations, but during the welding process, they can usually only move horizontally and vertically for welding. It is difficult to weld when facing a cylindrical welded part, and it is also impossible to weld upward, which makes welding more limited. Summary of the invention

[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] See also Figure 1-6 A multifunctional intelligent shockproof display stand welding mechanism comprises a workbench 1 and a display stand, the display stand comprises a welding plate 2 and a bracket 7, a top plate 32 is fixedly mounted on the workbench 1, a servo motor is fixedly mounted on the top plate 32, a screw rod 33 is fixedly mounted on the output end of the servo motor, and a slide plate 31 is threadedly sleeved on the screw rod 33;

[0030] A sliding frame 51 is vertically slidably mounted on the slide plate 31, an annular outer frame 52 is fixedly mounted on the slide plate 31, a rotating wheel 53 is threadedly sleeved on the sliding frame 51, an annular plate 54 is slidably mounted inside the annular outer frame 52, a connecting frame 55 is fixedly mounted on the annular plate 54, a rotating shaft 57 is rotatably mounted inside the connecting frame 55, a welding gun 56 is fixedly mounted on the rotating shaft 57, a connecting frame 55 is fixedly mounted on the side wall of the connecting frame 55, a sliding bar 59 is vertically slidably mounted inside the connecting frame 55, and a spiral ring rod 513 is fixedly mounted on the annular outer frame 52;

[0031] During the rising or falling process of the slide plate 31, the welding gun 56 will rotate around the bracket 7 to perform welding as the movement stroke progresses. Meanwhile, during the rising or falling movement process, the welding gun 56 will adaptively rotate to align with the welding position.

[0032] In another embodiment of the present invention: the sliding frame 51 includes two contact plates, and a round rod is fixedly installed between the two contact plates;

[0033] The round rod and the rotating wheel 53 are threadedly connected. When the slide plate 31 moves down, as the contact plate at the bottom of the slide frame 51 is released from the workbench 1, the slide frame 51 will not be able to move, but the slide plate 31 will continue to move down. At this time, the slide frame 51 will move up relative to the slide plate 31. At this time, as the slide frame 51 and the slide plate 31 move relative to each other, the round rod will drive the rotating wheel 53 to rotate. At this time, the two rotating wheels 53 rotate in the same direction, and the rotating wheel 53 and the annular plate 54 are frictionally fitted. Therefore, when the rotating wheel 53 rotates, the rotating wheel 53 will drive the annular plate 54 to rotate synchronously, so as to facilitate the annular plate 54 to drive the connecting frame 55 to move. At this time, the connecting frame 55 will drive the welding gun 56 to rotate in a circle around the bracket 7, so as to facilitate the welding gun 56 to perform circular welding on the bracket 7.

[0034] In another embodiment of the present invention: a notch is provided on the annular outer frame 52, the annular plate 54 and the spiral ring rod 513;

[0035] The bracket 7 can be placed in the middle of the annular outer frame 52 through the gap.

[0036] In another embodiment of the present invention: a limit frame 58 is fixedly installed on the side wall of the connection frame 55, and the number of the limit frames 58 is two. The two limit frames 58 are respectively located at the upper and lower ends of the rotating shaft 57, and the limit frames 58 are offset from the rotating shaft 57;

[0037] The slide bar 59 is arranged to fit the surface of the rotating shaft 57;

[0038] The slide bar 59 is inserted into the inner part of the limit frame 58, and the friction coefficient between the inner wall of the limit frame 58 and the slide bar 59 is relatively large, so that the slide bar 59 will not slide freely. However, when the slide plate 31 moves down to the specified position, the bottom end of the slide bar 59 contacts the workbench 1, and the slide bar 59 will move up. At this time, as the slide bar 59 moves up, the rotation shaft 57 will be driven to rotate due to the fit between the slide bar 59 and the rotation shaft 57. Figure 4 When the slide bar 59 moves up relative to the connecting frame 55, the rotating shaft 57 will be driven to rotate counterclockwise, thereby driving the welding gun 56 to rotate downward, and at the same time, the extension plate 510 on the rotating shaft 57 will move up until the extension plate 510 contacts the bottom end of the upper connecting frame 55, thereby limiting the continued rotation of the rotating shaft 57. When the slide plate 31 moves up, the slide plate 31 will drive the annular outer frame 52 to move up until the top end of the slide bar 59 contacts the upper welding plate 2. At this time, the slide bar 59 will move down, and at the same time, the slide bar 59 will drive the welding gun 56 to rotate upward, until the welding gun 56 rotates upward, and the top end of the slide frame 51 contacts and abuts against the top plate 32.

[0039] In another embodiment of the present invention: an extension plate 510 is fixedly mounted on the rotating shaft 57, a convex strip 511 is fixedly mounted on the extension plate 510, a connecting strip 512 is fixedly mounted on the convex strip 511, wherein the connecting strip 512 is L-shaped;

[0040] When the bottom end of the slide bar 59 contacts the lower welding plate 2, it will drive the shaft 57 to rotate, and the shaft 57 will drive the extension plate 510 to rotate. As the extension plate 510 rotates, until the shaft 57 rotates downward to the maximum angle, the top of the convex strip 511 and the connecting strip 512 will contact the bottom end of the upper spiral ring rod 513. At this time, the bottom end of the slide frame 51 driven by the slide plate 31 will contact the workbench 1. At this time, the slide frame 51 moves up relative to the slide plate 31. At this time, the slide frame 51 will drive the rotating wheel 53 to rotate. As the rotating wheel 53 rotates, it will drive the annular plate 54 to rotate. At this time, the annular plate 54 will drive the connecting frame 55 to move in a circular manner. Figure 3 When the slide plate 31 moves downward, the connecting frame 55 rotates clockwise. At this time, as the connecting frame 55 rotates, it will drive the convex strip 511 to move. At this time, the convex strip 511 and the connecting strip 512 will move at the bottom end of the spiral ring rod 513. When the connecting frame 55 moves clockwise, the bottom end of the spiral ring rod 513 will gradually extend downward, so the connecting strip 512 and the convex strip 511 will rotate downward, thereby driving the rotating shaft 57 to rotate. At this time, the welding gun 56 will rotate upward, so that when the annular outer frame 52 moves downward, the welding gun 56 can be passively raised, so that the flame of the welding gun 56 is always sprayed toward the bottom end of the bracket 7 and the weld of the welding plate 2 below, until the connecting frame 55 rotates one circle to the original position, and the connecting strip 512 and the convex strip 511 will also be reset;

[0041] The connecting strip 512 is located on one side of the convex strip 511. Since a notch is provided on the spiral ring rod 513, when the convex strip 511 passes over the notch, the connecting strip 512 will still abut against the spiral ring rod 513, thereby preventing the notch from affecting the rotation of the rotating shaft 57. When the convex strip 511 completely passes over the notch, the convex strip 511 will contact the spiral ring rod 513 again, and at this time the connecting strip 512 will pass over the notch. Through the cooperation of the connecting strip 512 and the convex strip 511, the notch will not affect the rotation of the rotating shaft 57.

[0042] In another embodiment of the present invention: a connecting frame 514 is fixedly mounted on the spiral ring rod 513;

[0043] The spiral ring rod 513 is fixedly connected to the annular outer frame 52 via a connecting frame 514 .

[0044] In another embodiment of the present invention: a positioning plate 6 is fixedly mounted on the workbench 1, and the positioning plate 6 is L-shaped;

[0045] After the bottom welding plate 2 is placed on the workbench 1, the welding plate 2 can be positioned by the positioning plate 6, so that the position of the bracket 7 is located at the center of the annular outer frame 52 to facilitate subsequent welding. At the same time, a notch is opened on the top plate 32, and the notch position of the top plate 32 is aligned with the hollow position of the positioning plate 6, so that the upper and lower layers of the welding plates 2 are positioned and aligned by the top plate 32 and the positioning plate 6.

[0046] In another embodiment of the present invention: a driving motor is fixedly installed on the workbench 1, a screw rod 42 is fixedly installed on the output end of the driving motor, a support plate 41 is provided on the workbench 1, a convex plate 44 is fixedly installed on the bottom end of the support plate 41, the screw rod 42 threadedly penetrates the convex plate 44, and a limiting strip 43 vertically penetrating the convex plate 44 is fixedly installed on the bottom end of the workbench 1;

[0047] The drive motor is started, and as the output shaft of the drive motor rotates, it will drive the screw rod 42 to rotate, and the screw rod 42 will drive the support plate 41 to slide up and down through the convex plate 44. As the support plate 41 slides up and down, it will adjust the height of the welding plate 2, so that the welding plate 2 is aligned with the positioning plate 6, and it can also be used for display racks of different heights. The limit strip 43 slides through the convex plate 44, so that the screw rod 42 can easily drive the convex plate 44 to move up and down when it rotates.

[0048] In another embodiment of the present invention: two rotating wheels 53 are provided, and the distance between the two rotating wheels 53 is greater than the length of the notch;

[0049] The two rotating wheels 53 are used so that when the gap approaches one of the rotating wheels 53, the other rotating wheel 53 can still drive the annular plate 54 to rotate. Furthermore, the rotating wheel 53 can be circumferentially provided with convex teeth, and the annular plate 54 is provided with tooth grooves. When the rotating wheel 53 rotates, the engagement of the convex teeth and the tooth grooves makes it easier to drive the annular plate 54 to rotate. The sliding frame 51 slides vertically in the slide plate 31 through the round rod. The friction coefficient between the round rod and the slide plate 31 is large, so that the round rod will not slide freely without being affected by external force. The sliding frame 51 will move only when the top or bottom end of the sliding frame 51 contacts the top plate 32 or the positioning plate 6.

[0050] In another embodiment of the present invention: the notch of the spiral ring rod 513 is provided with a rounded corner;

[0051] When the convex strip 511 and the connecting strip 512 move along the surface of the spiral ring rod 513 until they are close to the notch of the spiral ring rod 513, the height of the spiral ring rod 513 has changed, so the heights of the ends of the spiral ring rod 513 at both ends of the notch are inconsistent. At this time, when the convex strip 511 passes over one end of the notch, it is easy to be flush with the other end, so that it cannot enter the bottom of the spiral ring rod 513. At this time, the rounded corner is set so that when the convex strip 511 passes over the notch, it can move to the bottom of the spiral ring rod 513 through the rounded corner;

[0052] The side walls of the connecting frame 55 are fixedly installed with side panels, and the connecting frame 55 is fixedly connected to the annular plate 54 through the side panels. The connection through the side panels leaves a gap between the connecting frame 55 and the annular plate 54. Therefore, when the rotating shaft 57 rotates to drive the extension plate 510 to move from the top to the bottom, the protruding strip 511 and the connecting strip 512 can pass through the gap, so that no abutment occurs.

[0053] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
