DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0035] like Figures 1 to 14 As shown, the spot welding device with a visual recognition device of the present invention comprises a box 1, a welding platform 2, a holding component 3 and a clamping component 4. A controller is arranged inside the box 1 to control the motion trajectory of the welding platform 2 and the robot 5. The holding component 3 is used to clamp the welding workpiece 6 so that the welding workpiece 6 can be limitedly placed on the support plate 7, thereby facilitating the welding work of the robot 5. The clamping component 4 is used to clamp the welding rod on the robot 5, thereby facilitating the welding work of the robot 5.

[0036] The welding workpiece 6 is composed of a transverse plate 8 and a symmetrically arranged vertical plate 9. A symmetrically arranged mounting groove 10 is arranged on the transverse plate 8. The mounting groove 10 is arranged through, and slots 11 are arranged on both sides of the middle of the vertical plate 9. The portion of the slot 11 is not through, so that the transverse plate 8 can be installed therein. The width of the slot 11 matches the thickness of the transverse plate 8, and the width of the mounting groove 10 matches the distance between the slots 11 and the slots 11, so that the installation of the vertical plate 9 and the transverse plate 8 is realized, thereby limiting the position of the transverse plate 8 by the vertical plate 9. By limiting the position of the welding workpiece 6 by holding the assembly 3, the robot arm 5 will not have the welding workpiece 6 offset during welding, thereby ensuring the accuracy of the welding workpiece 6.

[0037] A welding platform 2 is provided at the upper end of the box body 1, and a welding workpiece 6 is placed on the welding platform 2 for welding. The welding platform 2 is composed of a base 12, a sliding seat 13 and a support plate 7. The welding workpiece 6 is specifically placed on the support plate 7. The sliding seat 13 is arranged in the middle of the base 12. The support plate 7 is installed on the base 12 and covers the sliding seat 13. The upper end surface of the sliding seat 13 contacts the lower end surface of the support plate 7, so that the position of the support plate 7 remains stationary, and the sliding seat 13 is driven to move by the driving member 14, so that the holding component 3 on the sliding seat 13 moves with the sliding seat 13. The holding component 3 is blocked by the baffle 15, so that the pressure member 16 pushes the first hinge 17 and the second hinge 18, and the sliding member 19 is pushed to slide on the holding seat 20 through the first hinge 17 and the second hinge 18, thereby driving the holding member 21 to rotate, so that the holding member 21 originally in a horizontal state rotates to a vertical state. The vertical plate 9 to be welded can be installed and placed between the two retaining members 21 to limit the position of the retaining members 21 so that it will not fall over.

[0038] In this application, Fig.13 and 14 It is one of the welding workpiece 6 structures that need to be welded. When the vertical plate 9 is placed, it needs to be kept stable by the holding assembly 3 so that it will not fall over, thereby facilitating the welding of other parts.

The support plate 7 is provided with a through hole 22 that cooperates with the retaining component 3, and the retaining member 21 is arranged in the through hole 22. A driving member 14 is provided at the lower end of the sliding seat 13, and the driving member 14 is a cylinder. The driving member 14 drives the sliding seat 13 to slide in the middle of the base 12, and makes the retaining component 3 extend out of the through hole 22 under force. The base 12 is provided with a plurality of baffles 15, and the sliding seat 13 is provided with a sliding groove 23 that cooperates with the baffle 15, so that during the movement of the sliding seat 13, the baffle 15 will not restrict the sliding seat 13, so that the baffle 15 makes relative movement in the sliding groove 23. The baffle 15 cooperates with the retaining component 3, so that the retaining component 3 is subjected to force.

[0040] The sliding seat 13 is provided with a sliding block 57, which can slide in the middle of the base 12.

[0041] The retaining assembly 3 is provided with a retaining seat 20, a pressure member 16, a first hinge member 17, a second hinge member 18, and symmetrically arranged sliding members 19 and retaining members 21.

[0042] The retaining seat 20 is provided with symmetrical dovetail grooves 24, and the bottom of the sliding member 19 is provided with a dovetail block 25 that cooperates with the dovetail grooves 24. Through the cooperation of the dovetail grooves 24 and the dovetail block 25, the sliding member 19 can slide smoothly on the retaining seat 20.

[0043] The retaining member 21 is hinged on the retaining seat 20 , and the pressure member 16 is limited by the baffle 15 , so that the first hinge member 17 and the second hinge member 18 are kept to slide the symmetrically arranged sliding members 19 on the retaining seat 20 and drive the retaining member 21 to rotate.

[0044] The sliding member 19 is provided with a plurality of second teeth 26 , and the retaining member 21 is provided with third teeth 27 cooperating with the second teeth 26 . The cooperation between the second teeth 26 and the third teeth 27 enables the sliding member 19 to drive the retaining member 21 to rotate during the sliding process.

[0045] The retaining member 21 is composed of a hinge portion 28 and a retaining plate 29, the retaining plate 29 is arranged in the through hole 22, and the third tooth 27 is arranged on the hinge portion 28. A hinge shaft 30 is arranged in the middle of the hinge portion 28, and the retaining member 21 is hinged to the base 12 through the hinge shaft 30. The retaining seat 20 is provided with a hinge block 31, and the hinge shaft 30 is arranged on the hinge block 31.

[0046] An extension plate 32 is provided on the retaining seat 20, and a strip groove 33 is provided on the extension plate 32.

After the pressure member 16 is blocked by the baffle 15, the spring 35 can be compressed by the positioning rod 38.

[0047] An outer cover 39 is provided at the upper end of the welding platform 2, and a mechanical arm 5 and a visual recognition device 53 are provided in the middle of the outer cover 39. The visual recognition device 53 is used to monitor the state of the mechanical arm 5 during welding. A clamping assembly 4 for mounting welding rods is provided on the mechanical arm 5. The clamping assembly 4 is provided with a housing 40, a cover plate 41, a motor 42, a first rotating shaft 43, a second rotating shaft 44 and symmetrically arranged clamping members 45. The motor 42 is arranged inside the housing 40, the first rotating shaft 43 is installed on the motor 42, and the second rotating shaft 44 is arranged inside the housing 40. The clamping member 45 is arranged on the first rotating shaft 43 and the second rotating shaft 44. When the motor 42 is started, it drives the symmetrically arranged clamping members 45 to rotate to clamp the welding rod.

[0048] The cover plate 41 is composed of a cover body 54 and an arc-shaped body 55. The cover plate 54 is provided with two small holes 56 for the rod body 47 to extend and rotate therein. The arc-shaped body 55 can block the welding rod, thereby facilitating the clamping of the clamping member 45.

When the arc surfaces 49 are arranged opposite to each other, the width of the clamping area 51 is the smallest, and of course the width is greater than the diameter of the welding rod, and when the plane surface 50 is arranged opposite to each other, the width is kept at the maximum, and the width is greater than the width of the welding rod, and the welding rod can be placed in the clamping area 51 at this time. Then the motor 42 is started to drive the two clamping members 45 to rotate, so that the arc surfaces 49 clamp the welding rod.

[0051] A notch 52 is provided on the arc surface 49 on the rod body 47. The notch 52 can limit the welding rod. If the arc surface 49 and the arc surface 49 are used to clamp the welding rod, when rotating from the plane 50, it is not necessary to rotate 180°, but the rotation angle is determined according to the diameter of the welding rod placed at that time.
