[0042] In order to make the technical personnel in the art better understand the scheme of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings.

[0043] Reference is made to the accompanying Figure 1 - the accompanying Figure 9 , the present application proposes a kind of automobile anti-collision beam welding workstation, including one sequence workbench 1, two sequence workbench 2, positioner 3 and welding robot 4;One sequence workbench 1 and two sequence workbench 2 are respectively installed at the two ends of positioner 3, and welding robot 4 is distributed in parallel at the end of positioner 3;Positioner 3 can drive one sequence workbench 1 or two sequence workbench 2 to have welding position close to welding robot 4 or piece position far from welding robot 4;One sequence workbench 1 includes first fixed unit 11 and second fixed unit 12, and first fixed unit 11 is used to fix extended beam 61 and light beam analysis palette 62;Second fixed unit 12 is used to fix beam bridge 63 on extended beam 61;Two sequence workbench 2 includes two sequence fixed unit 20 and two sequence clamping unit 21, and two sequence fixed unit 20 is used to fix beam body 60 and extended beam assembly;Two sequence clamping unit 21 is used to fix left support 66, right support 67, several beam supports 64 and several beam tubes 65 on beam body 60.

[0044] Specifically, the welding robots 4 are provided in two, and the two welding robots 4 are symmetrically arranged; the first fixing units 11 and the second fixing units 12 are both provided in two, the two first fixing units 11 are symmetrically distributed on the two sides of the first workbench 1, and the two second fixing units 12 are symmetrically arranged and are arranged between the two first fixing units 11, that is, one first fixing unit 11 and one second fixing unit 12 are distributed on the left side, and the other first fixing unit 11 and the other second fixing unit 12 are distributed on the right side. When the positioner 3 is in the welding position of the first workbench 1, the two welding robots 4 can respectively weld the first workbench 1 on the left side and the right side, thereby improving the welding efficiency.

[0046] Referring to the accompanying drawings Figure 3 and the accompanying drawings Figure 4 The first fixing unit 11 includes a first support structure 111 and a first clamping structure 112. The first support structure 111 is used for supporting and fixing the light beam analysis palette 62. The first clamping structure 112 is used for clamping the extended beam 61 and fixing the extended beam 61 on the light beam analysis palette 62. The first support structure 111 is provided with a plurality of first positioning portions 111a corresponding to the light beam analysis palette 62. The second fixing unit 12 includes a second support structure 121 and a second clamping structure 122. The second support structure 121 is used for supporting and fixing the extended beam 61 welded with the light beam analysis palette 62. The second clamping structure 122 is used for clamping the beam bridge 63 and fixing the beam bridge 63 on the extended beam 61. The second support structure 121 is provided with a plurality of second positioning portions corresponding to the light beam analysis palette 62.

[0047] Specifically, since the first support structure 111 and the second support structure 121 are both directly supporting and fixing the light beam analysis palette 62, in order to improve the equipment utilization of the workstation, the first support structure 111 and the second support structure 121 are designed with the same structure, and only the first support structure 111 is described in detail in this embodiment; the first support structure 111 specifically includes a bottom plate for supporting the light beam analysis palette 62, compression rods distributed at both ends of the bottom plate, and a protruding structure for preventing mistakes and positioning is arranged on the bottom plate corresponding to the through hole on the light beam analysis palette 62 to form a first positioning part 111a; the first clamping structure 112 specifically adopts a clamp structure to clamp and fix the extended beam 61 on the light beam analysis palette 62; the extended beam 61 and the light beam analysis palette 62 can be fixed by the first fixing unit 11, so as to be welded into an extended beam 61 with a light beam analysis palette 62; further, in order to facilitate the connection and fixation of the extended beam 61 and the beam body 60, a beam bridge 63 for connecting the extended beam 61 and the beam body 60 is arranged on the extended beam 61, therefore, the second support structure 121 is arranged in this embodiment to support and fix the extended beam 61 with the light beam analysis palette 62, and the beam bridge 63 is clamped and fixed on the top position of the extended beam 61 by the second clamping structure 122, so as to be welded into a complete extended beam assembly, facilitating the development of the second sequence welding work.

[0048] Referring to the accompanying Figure 5 and the accompanying Figure 6 , the second sequence fixing unit 20 includes two second sequence support structures 200, two end compression structures 201 and two middle clamping structures 202; the two second sequence support structures 200 are symmetrically distributed on the second sequence workbench 2, and the second sequence support structure 200 is used for supporting and fixing the extended beam assembly; the two middle clamping structures 202 are between the two second sequence support structures 200, and the two middle clamping structures 202 are used for clamping the middle section of the beam body 60; the two end compression structures 201 are arranged corresponding to the two second sequence support structures 200, and the two end compression structures 201 respectively compress and fix the two ends of the beam body 60 on the beam bridges 63 of the two extended beam assemblies. Specifically, the second sequence support structure 200 adopts the same structure design as the first support structure 111 in the first sequence workbench 1 in this embodiment, directly supporting and fixing the light beam analysis palette 62 of the extended beam assembly, clamping the beam body 60 by the two middle clamping structures 202, and contacting the two ends of the beam body 60 with the beam bridges 63 on the extended beam assembly, and finally compressing the two ends of the beam body 60 on the extended beam assembly by the two end compression structures 201.

[0049] Referring to the accompanying Figure 6In order to facilitate the assembly of second-order parts and ensure that the welding sequences of the two welding robots 4 do not interfere with each other, thereby improving welding efficiency, the second-order clamping unit 21 includes two first clamps 211, two second clamps 212 and two third clamps 213; the two first clamps 211 are respectively placed at the two ends of the beam body 60, and the two first clamps 211 are respectively used to clamp the left bracket 66 and the right bracket 67, and fix the left bracket 66 and the right bracket 67 to the two ends of the beam body 60 respectively; the two second clamps 212 are respectively used to clamp the two beam brackets 64, and fix the two beam brackets 64 to the middle section of the beam body 60; the two third clamps 213 are respectively used to clamp the two beam tubes 65, and fix the two beam tubes 65 to the middle section of the beam body 60. Specifically, since the welding points of the left bracket 66 and the right bracket 67 are located on the side of the beam body 60, the two first clamps 211 are distributed on the side close to the welding robot 4, and the left bracket 66 and the right bracket 67 are respectively fixed at the specified positions of the beam body 60 by the two first clamps 211; and the welding points of the beam tube 65 and the beam bracket 64 are at the top and top edges of the beam body 60, so there is no requirement for the distribution position of the second clamp 212 and the third clamp 213, and it is sufficient to avoid interference with the rotation and welding of the welding robot 4.

[0050] In order to prevent the welding robot 4 from affecting the worker's assembly effect on another sequence when performing welding work, a light shielding plate 30 is also provided on the positioner 3. The light shielding plate 30 is used to separate the first-sequence workbench 1 and the second-sequence workbench 2. The light shielding plate 30 prevents the light generated by the welding robot 4 during welding from directly shining into the worker's eyes, so that the worker can quickly complete the assembly operation of another sequence.

[0051] To further improve the safety of the workstation, the workstation also includes an outer baffle 5, which encloses the first-order workbench 1, the second-order workbench 2, the positioner 3, and the welding robot 4. The outer baffle 5 is provided with a loading and unloading entrance 50, which is arranged away from the welding robot 4. Specifically, the loading and unloading entrance 50 and the welding robot 4 are arranged at both ends, so that the loading cycle and the welding cycle are independent of each other, thereby improving the welding efficiency of the workstation. In addition, in actual production work, parts can be placed near the loading and unloading entrance 50, reducing the transfer operation of parts, improving the loading and unloading efficiency, and reducing the waste of manpower and material resources, thereby improving the welding efficiency of the workstation.
