DETAILED DESCRIPTION

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Example 1, reference Figures 1 to 5 , which is the first embodiment of the present invention, provides a welding device for metal sheet processing, including a supporting mechanism 100, on which a fixing mechanism 200 and a welding robot arm 300 are provided; the welding robot arm 300 is used for automatic welding.

[0027] The support mechanism 100 is provided with a support frame 101a, and the support mechanism 100 is provided with two symmetrically arranged positioning bars 103; the two symmetrically arranged positioning bars 103 are arranged on both sides of the part of the plate to be welded, and the welding robot arm 300 welds the middle part of the positioning bars 103.

[0028] Among them, the supporting mechanism 100 includes a mounting plate 101 and a limiting plate 102 arranged on the mounting plate 101, the limiting plate 102 is connected to the positioning bar 103, the supporting frame 101a is arranged on the mounting plate 101, the welding robot arm 300 is installed on the mounting plate 101, and the limiting plate 102 is used to limit the plate.

[0029] Preferably, the limiting plate 102 is provided with a side plate 102a, and the side plate 102a is provided with a connecting frame 102b. The side plate 102a is connected to the mounting plate 101 via the connecting frame 102b. The setting of the side plate 102a facilitates the positioning of the plate, so that when the upper surface of the plate is in contact with the bottom of the positioning strip 103, the welding position can be centered.

[0030] The fixing mechanism 200 includes a rotating motor 201 fixed on the support frame 101 a , and a conveying member 202 disposed at a rotating end of the rotating motor 201 ; the conveying member 202 can be controlled to rotate by the rotating motor 201 .

[0031] There are two conveying members 202 symmetrically arranged on the support frame 101a. The two symmetrically arranged conveying members 202 respectively press against the inner surface of the plate, so that the upper surface of the plate fits with the bottom of the positioning strip 103, thereby clamping and fixing the plate.

[0032] It should be noted that the device is adapted for assembly line operation, and one side of the device is provided with upper and lower conveyor lines, the upper conveyor line is used to convey the plates to the bottom of the limit plate 102a, and the lower conveyor line can receive the fallen welded plates.

[0033] Specifically, the conveying member 202 includes two parallel short support parts 202a and two parallel long support parts 202b. The short support parts 202a and the long support parts 202b are connected in sequence to form a parallelogram. Support wheels 202c are provided at the connection between the short support parts 202a and the long support parts 202b, and also include a conveying belt 202d arranged on the outer wall of the support wheel 202c. The design of the short support parts 202a and the long support parts 202b, one short and one long, can increase the length of the fixing mechanism 200 and reduce the width, so as to facilitate insertion into the interior of the square plate formed after bending. At the same time, the support area can be increased when fixing the plate, thereby improving the fixing effect and the stability of the welding process.

[0034] Furthermore, the conveying member 202 also includes a support arm 202e fixed on the short support portion 202a, and a driving wheel 202f is provided on the support arm 202e. The outer wall of the driving wheel 202f is in contact with the surface of the conveying belt 202d. The operation of the driving wheel 202f can make the conveying belt 202d operate, thereby realizing the conveying operation of the plate, which is convenient for docking with the assembly line.

[0035] When in use, firstly, the conveying member 202 is controlled to rotate by the rotating motor 201 so that the front end of the conveying member 202 is aligned with the center of the square plate. At this time, the front end of the plate is sleeved on the outside of the conveying member 202 through the conveying of the upper conveyor line. The angle of the conveying member 202 is adjusted again so that the conveying belt 202d fits the inner surface of the plate. The operation of the driving wheel 202f causes the conveying belt 202d to move, so that the square plate is completely sleeved on the outside of the conveying member 202 and is separated from the upper conveyor line. When the conveying member 202 is controlled to rotate by the rotating motor 201, the plate can be lifted by the conveying member 202. When the plate is lifted, the position of the plate is adjusted by the guidance of the side plate 102a, so that the welding part can be located between the two positioning sleeves 103 until the bottom of the two positioning strips 103 and the top surface of the plate are in conflict. At this time, the two supporting wheels 202c on the conveying member 202 press against the conveying belt 202d to make it conflict with the inner surface of the plate. Figure 3 At this time, both sides of the plate that needs to be welded are squeezed and fixed, and then the welding robot arm 300 is used to weld the butt joint in the middle of the plate; after welding is completed, the conveyor 202 is rotated to make the plate approach the lower conveyor line, and the conveyor 202 is used to transport it so that it falls on the lower conveyor line to complete the welding operation.

[0036] In summary, when the device is used for welding, the two sides of the welding part can be pressed and fixed respectively through two symmetrically arranged conveying parts 202, and it has a large support area, which can improve the stability during welding. The side plate 102a can realize the centering of the welding part, which can improve the forming effect of the plate after welding, and the bent and formed plate can be welded into a square tube. In addition, the device can adapt to the automated operation of the assembly line, which greatly improves the efficiency of the operation.

[0037] Example 2, reference Figure 1 to Figure 5 , which is the second embodiment of the present invention. Different from the previous embodiment, a limit frame 202e-1 is provided on the support arm 202e; the fixing mechanism 200 also includes a deformable member 203 slidably arranged in the limit frame 202e-1, and a cylinder 204 is provided on the deformable member 203; the limit frame 202e-1 and the support arm 202e are fixedly connected, and the support arm 202e is fixedly connected to one of the short support parts 202a, and the extension and retraction of the cylinder 204 can control the deformable member 203 to slide in the limit frame 202e-1.

[0038] The short support portion 202a and the long support portion 202b are rotatably connected. Through the rotation between the short support portion 202a and the long support portion 202b, in conjunction with the parallelogram structure, the length and width of the conveying member 202 can be changed, and the shape of the conveying member 202 can be adjusted. The circumference of the parallelogram will never change, and therefore, the conveying belt will not fall off. The conveying belt can always remain on the outside of the four support wheels 202c without the need to adjust the conveying belt.

[0039] Specifically, the deformable member 203 includes a slide plate 203a slidably arranged in the limit frame 202e-1, and a smooth groove 203b arranged on the slide plate 203a. The slide plate 203a is provided with a side plate 203c, and also includes a side sliding groove 203d arranged on the side plate 203c. The side plate 203c and the slide plate 203a are arranged in a Y shape, and the smooth groove 203b and the side sliding groove 203d are arranged in a Y shape.

[0040] Furthermore, a first limiting rod 202a-4 is provided on the short support portion 202a, and the first limiting rod 202a-4 is slidably connected to the smooth groove 203b; a second limiting rod 202b-4 is provided on the long support portion 202b, and the second limiting rod 202b-4 is slidably connected to the side sliding groove 203d.

[0041] The rest of the structure is the same as that of Example 1.

[0042] When in use, the cylinder 204 is telescopically controlled to control the deformation member 203 to slide in the limit frame 202e-1, so that the angle between the short support part 202a and the long support part 202b can be controlled, thereby changing the shape of the conveying member 202. Therefore, when docking with the upper conveyor line, the angle between the short support part 202a and the long support part 202b can be reduced first, so that the length of the conveying member 202 is increased, which is more conducive to the upper conveyor line to convey the plate to the outside of the conveying member 202. After the plate is sleeved on the outside of the conveying member 202, the shape of the conveying member 202 can be controlled by the telescopic cylinder 204, so that the upper surface of the conveying belt 202d can better fit the inner wall of the square plate. Therefore, when the driving wheel 202f controls the operation of the conveying belt 202d, it can increase the friction force, so that the square plate moves completely around the outside of the conveying member 202.

[0043] When the rotating motor 201 rotates the conveying member 202 to lift the square tube, refer to Figure 3 When the upper left support wheel 202c is against the square pipe, the cylinder 204 can be extended and retracted to control the deformation member 203 to slide in the limit frame 202e-1, thereby reducing the angle between the short support part 202a and the long support part 202b, so that the upper right support wheel 202c is pressed upward, thereby improving the fixing effect and fixing strength of the plate, and because the shape of the conveying member 202 is adjustable, it can be suitable for the processing of plates of more specifications and thicknesses.

[0044] Example 3, reference Figure 1 to Figure 5 , which is the third embodiment of the present invention. Different from the previous embodiment, the short support portion 202a includes a first rotating seat 202a-1, and a first threaded sleeve 202a-2 rotatably arranged on the first rotating seat 202a-1, and the inner wall of the first threaded sleeve 202a-2 is threadedly connected with a first screw 202a-3. By rotating the first threaded sleeve 202a-2, the length of the short support portion 202a can be adjusted.

[0045] Specifically, the long support portion 202b includes a second rotating seat 202b-1, and a second threaded sleeve 202b-2 rotatably arranged on the second rotating seat 202b-1, and the inner wall of the second threaded sleeve 202b-2 is threadedly connected to a second screw 202b-3. By rotating the second threaded sleeve 202b-2, the length of the long support portion 202b can be adjusted.

[0046] The rest of the structure is the same as that of Example 2.

[0047] When in use, the conveyor belt 202d can be disassembled and installed by means of the short support part 202a and the long support part 202b of adjustable length, and after the conveyor belt 202d is loosened, it is only necessary to increase the length of the short support part 202a or the long support part 202b at the same time, which is convenient for maintenance. In addition, due to the arrangement of the short support part 202a and the long support part 202b, the conveyor member 202 can be suitable for belts of different lengths, or the shape of a belt of the same length can be changed by adjusting the respective lengths of the short support part 202a and the long support part 202b to improve the applicability of the device.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
