[0056] The embodiments of the present application provide a positioning fixture and a welding device for solving the technical problem of low splicing accuracy of automobile door rings.

[0057] In the embodiments of the present application, Figure 2 and Figure 4 As shown, the positioning fixture includes a mounting seat 2, an adsorption assembly 3 and a driving assembly 1, wherein at least two mounting seats 2, adsorption assemblies 3 and driving assemblies 1 are provided, and the driving assemblies 1 are provided at intervals; the mounting seat 2 is connected to the output end of the driving assembly 1; the adsorption assembly 3 is provided on the mounting seat 2, and the adsorption assembly 3 is used to adsorb the plate 40. Among them, the driving assembly 1 is used to drive the adsorption assembly 3 to move through the mounting seat 2, so that the adsorption assemblies 3 on two adjacent mounting seats 2 drive the plates 40 to be spliced.

[0058] The mounting seat 2 of the embodiment of the present application is arranged at the output end of the driving component 1, and the adsorption component 3 is arranged on the mounting seat 2, so that the mounting seat 2 is driven to move by the driving component 1, and then the adsorption component 3 is driven to move by the mounting seat 2; the adsorption component 3 is used to adsorb the plate 40, so the plate 40 can be first loaded onto the adsorption component 3 so that the adsorption component 3 adsorbs the plate 40; and then the plate 40 is driven to move by the adsorption component 3 to splice the plates 40 together; when deviation occurs in the splicing of the plates 40, so that the plates 40 cannot be aligned at the splicing position, the mounting seat 2 can be driven by the driving component 1, and then the adsorption component 3 can be driven by the mounting seat 2, and then the plate 40 can be driven by the adsorption component 3 to adjust the posture of the plates 40, so that two adjacent plates 40 can be aligned at their splicing positions, thereby improving the splicing accuracy of the plates 40, and then the splicing accuracy of the automobile door ring can be improved to improve the welding quality of the automobile door ring.

[0059] It can be understood that the drive assembly 1 can be arranged around the same central position to splice the plate 40 into a ring shape, so that it can be applied to the welding of the automobile door ring. The drive assembly 1 can be surrounded by a ring shape or an ellipse shape. That is, the distribution position of the drive assembly 1 can be arranged according to the application scenario.

[0060] In one embodiment, if Figure 4 As shown, the mounting base 2 is a plate-like structure to simplify the structure of the mounting base 2 and facilitate the arrangement of the adsorption component 3 on the mounting base 2 .

[0061] In one embodiment, if Figure 4 and Figure 5 As shown, the driving assembly 1 includes a first driving unit 11, and the mounting seat 2 is connected to the output end of the first driving unit 11. The first driving unit 11 is used to drive the mounting seat 2 to move back and forth along the first straight line direction. The first driving unit 11 drives the mounting seat 2 to move, and then drives the adsorption assembly 3 to move through the mounting seat 2, and then drives the plate 40 to move along the first straight line direction through the adsorption assembly 3, so that the position of the plate 40 in the first straight line direction can be adjusted to eliminate the deviation of two adjacent plates 40 in the first straight line direction, so that the two adjacent plates 40 are aligned in the first straight line direction.

[0062] In one embodiment, if Figure 4 and Figure 5 As shown, the driving assembly 1 further includes a second driving unit 12, which is disposed at the output end of the first driving unit 11, and the mounting seat 2 is disposed at the output end of the second driving unit 12, and the second driving unit 12 is used to drive the mounting seat 2 to reciprocate along a second linear direction, wherein the second linear direction is perpendicular to the first linear direction.

[0063] The first driving unit 11 can drive the second driving unit 12 to move in the first linear direction, and the second driving unit 12 can drive the mounting base 2 to move in the second linear direction, so that the mounting base 2 can be driven by the second driving unit 12 to move in the first linear direction and the second linear direction respectively. The mounting base 2 then drives the adsorption component 3 to move, and then the adsorption component 3 drives the plate 40 to move in the first linear direction and the second linear direction respectively, so as to adjust the posture of the plate 40 so that two adjacent plates 40 can be aligned in the first linear direction and the second linear direction.

[0064] In one embodiment, if Figure 4 and Figure 5 As shown, the driving assembly 1 further includes a third driving unit, which is disposed at the output end of the second driving unit 12, and the mounting seat 2 is disposed at the output end of the third driving unit, and the third driving unit is used to drive the mounting seat 2 to rotate around a third linear direction. The first linear direction, the second linear direction and the third linear direction are perpendicular to each other.

[0065] The first drive unit 11 can drive the second drive unit 12 to move in the first straight line direction, the second drive unit 12 can drive the third drive unit to move in the second straight line direction, and the third drive unit can drive the mounting base 2 to rotate around the third straight line direction. Thus, the mounting base 2 can be driven by the third drive unit to move in the first straight line direction, move in the second straight line direction, and rotate around the third straight line direction. The mounting base 2 can drive the adsorption component 3 to move, and the adsorption component 3 can drive the plate 40 to move, so that the posture of the plate 40 can be adjusted so that two adjacent plates 40 can be aligned in the first straight line direction, the second straight line direction, and the third straight line direction.

[0066] like Figure 5 As shown, the first straight line direction is parallel to the Y direction, the second straight line direction is parallel to the X direction, and the third straight line direction is parallel to the Z direction.

[0067] In this embodiment, the third straight line direction can be parallel to the vertical direction, and the first straight line direction can be parallel to the direction in which two adjacent plates 40 approach each other. At this time, by adjusting the position of the plate 40 in the first straight line direction, the width of the joint seam between the two adjacent plates 40 can be adjusted; by adjusting the position of the plate 40 in the second straight line direction, the degree of alignment of the two adjacent plates 40 in the width direction can be adjusted; by adjusting the rotation position of the plate 40 around the third straight line direction, the consistency of the joint seam between the two adjacent plates 40 can be adjusted, that is, the width of the entire joint seam can be made consistent, or the width of the joint seam can be gradually increased from one end to the other.

[0068] It can be understood that the first linear direction, the second linear direction and the third linear direction of the present embodiment are compared within the same drive assembly 1, and are compared based on the same drive assembly 1, reflecting the relationship between the first linear direction, the second linear direction and the third linear direction within the same drive assembly 1. The first linear directions or second linear directions of different drive assemblies 1 may be parallel or non-parallel.

[0069] In one embodiment, if Figures 2 to 4 As shown, adsorption components 3 are provided at both ends of the mounting seat 2, and the driving component 1 is used to drive the adsorption components 3 on two adjacent mounting seats 2 to splice through the mounting seat 2, so that the splicing seam formed by the two adjacent adsorption components 3 and the splicing seam formed by the adsorption component 3 driving the plate 40 to splice are aligned in the third straight line direction, so that the orthographic projection of the splicing seam of the plate 40 in the plane perpendicular to the third straight line direction (that is, in the horizontal plane) is located within the orthographic projection of the splicing seam between the two adjacent adsorption components 3 in the plane perpendicular to the third straight line direction. Since the splicing seam of the adsorption component 3 can be aligned with the splicing seam of the plate 40, the adsorption component 3 can be as close to the splicing seam of the plate 40 as possible to improve the stability of the splicing position of the plate 40, thereby improving the precision of the welding of the plate 40. The splicing seam of the adsorption component 3 can also facilitate slag removal so that the slag box 4 can receive the slag.

[0070] In this embodiment, the adsorption assembly 3 can be used to adsorb the end of the plate 40 so that the edge of the adsorption assembly 3 is parallel to the edge of the splicing edge of the plate 40, so that after the plates 40 are spliced, the splicing seam formed between the adsorption assemblies 3 on two adjacent mounting seats 2 and the splicing seam between two adjacent plates 40 can be aligned in the third straight line direction. Of course, the edge of the adsorption assembly 3 may not be parallel to the edge of the splicing edge of the plate 40.

[0071] The edge of the splicing side of the plate 40 can protrude from the edge of the adsorption component 3 so that the width of the splicing seam of the plate 40 can be smaller than the width of the splicing seam of the adsorption component 3, thereby avoiding the adsorption component 3 interfering with the adjustment of the splicing seam width of two adjacent plates 40.

[0072] In one embodiment, if Figure 4 and Figure 5 As shown, the positioning fixture further includes a slag receiving box 4, which is arranged on the side of the adsorption component 3 and is used to receive slag falling from the joints between the adsorption components 3 after splicing, so as to avoid the accumulation of slag generated after welding.

[0073] Optionally, the slag receiving box 4 can be arranged on the mounting seat 2 .

[0074] In one embodiment, if Figure 4 and Figure 5As shown, the positioning fixture further includes a dust extraction unit 5, which is disposed at the end of the adsorption assembly 3. The dust extraction unit 5 is used to generate negative pressure to absorb dust generated after welding the plates 40. Since the dust extraction unit 5 is relatively large in size, the dust extraction unit 5 is disposed at the end of the adsorption assembly 3 to avoid interference with the width adjustment of the joint seam between two adjacent plates 40. It can also prevent the dust extraction unit 5 from being damaged by the laser used for welding the plates 40 due to light leakage.

[0075] Optionally, the dust extraction unit 5 can be arranged on the mounting base 2 .

[0076] In one embodiment, if Figure 4 and Figure 5 As shown, the positioning fixture further includes a blowing unit 6, which is disposed on the side of the adsorption assembly 3, and the blowing unit 6 is used to blow air toward the joint seam between the adsorption assemblies 3 after splicing. The blowing unit 6 is used to blow out a shielding gas toward the joint seam between the adsorption assemblies 3 after splicing, so that the shielding gas can reach the joint seam of the plate 40, so that when the joint seam of the plate 40 is welded, the shielding gas can protect the plate 40 to prevent the welding position of the plate 40 from being oxidized. The shielding gas can also reduce the formation of plasma, and an ionized gas cloud can be formed above the joint seam of the plate 40 to reduce the blocking and distortion of the laser beam used for laser welding of the plate 40 by the plasma, thereby improving the welding quality. The shielding gas can also improve the stability of the molten pool when welding the plate 40.

[0077] Alternatively, if Figure 5 As shown, the blowing unit 6 can be arranged on the mounting seat 2.

[0078] In one embodiment, if Figure 5 As shown, the side surface of the adsorption assembly 3 for setting the slag box 4 and the blowing unit 6 is adjacent to the end surface of the adsorption assembly 3 for setting the dust extraction unit 5, that is, the end surfaces of the adsorption assembly 3 at both ends along the second straight line direction are used to set the dust extraction unit 5. The side surface of the adsorption assembly 3 facing another adjacent mounting seat 2 is used to set the slag box 4 and the blowing unit 6.

[0079] In one embodiment, if Figure 4 and Figure 5 As shown, the side of the adsorption assembly 3 facing another adjacent mounting seat 2 is provided with a mounting groove 311, and the slag receiving box 4 and the air blowing unit 6 are both arranged in the mounting groove 311. The damage of the laser to the air blowing unit 6 and the slag receiving box 4 caused by light leakage can be reduced. The slag receiving box 4 and the air blowing unit 6 can also be prevented from interfering with the adjustment of the width of the joint seam of the plate 40. Specifically, the air blowing port 61 of the air blowing unit 6 is arranged in the mounting groove 311.

[0080] In one embodiment, if Figure 5As shown, the blowing unit 6 is located above the slag receiving box 4 , which can prevent the slag receiving box 4 from interfering with the blowing of the blowing unit 6 .

[0081] In one embodiment, if Figure 2 and Figure 4 As shown, the positioning fixture further includes a support member 7, which is disposed on the mounting seat 2 and is used to support the plate 40. The support of the plate 40 by the support member 7 and the adsorption assembly 3 can improve the stability of the positioning plate 40 and reduce the requirement for the adsorption force of the adsorption assembly 3.

[0082] In one embodiment, if Figure 2 and Figure 3 As shown, a flexible layer or brush 71 is provided on the side of the support member 7 facing away from the mounting seat 2 , and the plate 40 can be supported by the flexible layer or brush 71 to avoid scratching the plate 40 , and the total weight of the support member 7 can also be reduced.

[0083] In one embodiment, if Figure 2 and Figure 3 As shown, the adsorption component 3 includes an electromagnet 31, which is arranged on the mounting seat 2 and is used to adsorb the plate 40. By using the characteristics of the electromagnet 31 generating magnetism when it is energized to adsorb the ferromagnetic plate 40, the adsorption efficiency and adsorption stability can be improved.

[0084] Optionally, the adsorption assembly 3 may include a vacuum adsorption component to adsorb the plate 40 using the principle of vacuum adsorption.

[0085] In one embodiment, the positioning fixture further includes a cooling unit, which is disposed on the electromagnet 31 to improve the heat dissipation efficiency of the electromagnet 31 .

[0086] Optionally, a water cooling channel may be provided in the electromagnet 31 to improve the heat dissipation efficiency of the electromagnet 31. A heat conducting plate may also be provided on the electromagnet 31 to improve the heat dissipation efficiency of the electromagnet 31 by heat conduction.

[0087] In one embodiment, if Figure 2 and Figure 3 As shown, the driving assembly 1 is used to drive the electromagnets 31 on two adjacent mounting seats 2 to splice through the mounting seat 2, so that the splicing seam between the two adjacent electromagnets 31 is aligned with the splicing seam of two adjacent plates 40 in the third straight line direction.

[0088] In one embodiment, if Figure 5 As shown, the slag box 4, the dust extraction unit 5 and / or the blowing unit 6 are arranged on the electromagnet 31. Specifically, the mounting groove 311 is arranged on the side of the electromagnet 31 facing another adjacent mounting seat 2, and the slag box 4 and the blowing unit 6 are arranged on the side of the electromagnet 31 facing another adjacent mounting seat 2.

[0089] In one embodiment, if Figure 2 and Figure 4 As shown, the positioning fixture also includes a base 8, and the driving component 1 is arranged on the base 8. The setting position of the driving component 1 on the base 8 is adjustable. In order to adjust the position of the driving component 1 according to the product to be welded, the welding of multiple products can be realized, and the compatibility of the positioning fixture is improved.

[0090] In this embodiment, the base 8 can be slidably mounted on a workbench so as to transport the base 8 to a loading position, unloading position or welding position. The base 8 can also be directly fixed on the ground, and during welding, the welding head can be directly moved above the base 8 to weld the plate 40.

[0091] In one embodiment, the positioning fixture further includes a fixing member, a first fixing hole is provided on the driving component 1, a plurality of second fixing holes are provided on the base 8, and the fixing member is passed through the first fixing hole and the second fixing hole to fix the driving component 1 on the base 8. Since a plurality of second fixing holes are provided on the base 8, the fixing member can be passed through different second fixing holes to set the driving component 1 at different positions, thereby improving the compatibility of the positioning fixture.

[0092] In one embodiment, a first fixing hole is disposed on the first driving unit 11 .

[0093] In one embodiment, if Figure 1 and Figure 2 As shown, the positioning fixture also includes a support frame 9, a first visual driving unit and a visual component 10, wherein the first visual driving unit is arranged on the support frame 9; the visual component 10 is connected to the output end of the first visual driving unit, and the first visual driving unit is used to drive the visual component 10 to move directly above the adsorption component 3 or avoid directly above the adsorption component 3. After the plate 40 is spliced, the first visual driving unit is controlled to drive the visual component 10 to move directly above the adsorption component 3, so as to capture the splicing seam of the plate 40 through the visual component 10, thereby detecting whether the plate 40 is moved to the target position, that is, detecting whether the splicing seam of the plate 40 meets the requirements. When the first visual driving unit drives the visual component 10 to avoid directly above the adsorption component 3, the plate 40 can be loaded onto the adsorption component 3, or unloaded from the adsorption component 3, so as to avoid the visual component 10 interfering with the loading and unloading of the plate 40.

[0094] In one embodiment, if Figure 1 and Figure 2As shown, the positioning fixture also includes a second visual drive unit 20, which is connected to the output end of the first visual drive unit, and the visual component 10 is arranged at the output end of the second visual drive unit 20, and the second visual drive unit 20 is used to drive the visual component 10 to move up and down. The first visual drive unit can drive the second visual drive unit 20 to move along the upper part close to the adsorption component 3, and the second visual drive unit 20 can drive the visual component 10 to move up and down, so that the visual component 10 can be close to or away from the adsorption component 3, so that the visual component 10 can be focused, and the clarity of the position where the visual component 10 grabs the plate 40 is improved.

[0095] In one embodiment, if Figure 1 and Figure 2 As shown, the visual component 10 includes a frame 101 and a plurality of visual units 102. The frame 101 is detachably arranged at the output end of the first visual driving unit; the visual unit 102 is arranged on the frame 101, and the visual unit 102 is arranged corresponding to the splicing seam of the spliced ​​plates 40. The visual unit 102 is arranged corresponding to the splicing seam of the spliced ​​plates 40, and the position of the splicing edge of each plate 40 can be captured by the visual unit 102 to determine whether to move the plate 40 to the target position so as to improve the splicing accuracy. Since the frame 101 is detachably arranged at the output end of the first visual driving unit, the frame 101 can be replaced according to actual needs, so that the visual unit 102 can correspond to the splicing seam when different plates 40 are welded, thereby improving the compatibility of the positioning fixture. Among them, the visual unit 102 can be a camera.
