Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laser intelligent welding, in particular to a computer case intelligent welding equipment based on multi-axis linkage. BACKGROUND

[0002] As a key structural part of bearing servers, workstations and high-performance personal computer core hardware, the manufacturing quality of the computer case directly affects the stability, electromagnetic shielding effectiveness and service life of the equipment. At present, the welding production of computer cases (mostly thin plate sheet metal structure) mainly has the following problems. The traditional welding (such as manual MIG / MAG welding or fixed automatic welding) relies on pre-point welding fixation. When welding long welds, due to the small heat capacity and fast heat conduction of thin plates, uneven heat input easily leads to asymmetric heat distribution on both sides of the weld, thereby causing welding deformation, undercut, incomplete penetration and other defects, which seriously affects the dimensional accuracy and structural rigidity of the case. The existing passive welding is difficult to realize online compensation for such deformation. In the face of the trend of small batch, multi-variety customized production, the existing welding equipment or fixture is often dedicated to a specific line, and it takes a long time to adjust the type. It is difficult to quickly adapt to the welding needs of cases of different sizes and different weld positions. Manual participation is involved in many aspects, the production efficiency is limited by the skill level of welders, the product quality consistency is poor, and most automatic welding equipment still uses preset fixed path and parameters for operation, which belongs to "open loop" control. It cannot sense the real-time changes of the weld gap caused by the micro-deviation of the workpiece assembly, the micro-observation of the plate or the difference in heat conduction during the welding process, so it cannot make dynamic adjustments, resulting in that the quality of the latter half is often difficult to guarantee when welding complex or long path welds.

DETAILED DESCRIPTION

[0042] Reference Figures 1-7 The present application provides a technical solution: a computer case intelligent welding equipment based on multi-axis linkage, comprising:

[0043] Machine table 1, the upper end of which is provided with X-axis guide rail 2, X-axis guide rail 2 is provided with Y-axis guide rail 3, Y-axis guide rail 3 is provided with Z-axis guide rail 4, Z-axis guide rail 4 is provided with C-axis motor 5, C-axis motor 5 is provided with B-axis motor 6, B-axis motor 6 is provided with laser welding head 7 located on the vertical plane;

[0044] Support mechanism 8 is arranged on the inner side of X-axis guide rail 2;

[0045] Clamping mechanism 9 is arranged on the outer peripheral side of support mechanism 8;

[0046] Conveying belt 10 is arranged along the direction of X-axis guide rail 2 and on both sides of support mechanism 8.

[0047] In the embodiment, one conveying belt 10 is used to convey the un-welded case, and the other conveying belt 10 is used to convey the welded case. Specifically, the un-welded case is placed on one conveying belt 10 and conveyed to the supporting mechanism 8, and then the un-welded case is lifted by the supporting mechanism 8 to the working space of the clamping mechanism 9, and then the side of the un-welded case is clamped and fixed by the clamping mechanism 9, so that the side plate of the un-welded case maintains a regular shape, so that the weld gap is tight and uniform. Through the cooperation of the X-axis guide rail 2, the Y-axis guide rail 3, the Z-axis guide rail 4, the C-axis motor 5 and the B-axis motor 6, the lower end of the laser welding head 7 is inclined to point to the weld, and the vertical plane where the laser welding head 7 is located is parallel to the two seam surfaces of the weld and is located at the center of the two seam surfaces, so that the uniformity of heat conduction in the area on both sides of the weld is maintained when the laser welding head 7 is welded.

[0048] In the embodiment, the supporting mechanism 8 comprises:

[0049] The lifting guide rail one 81 is arranged on the machine table 1, and the lifting plate 82 is arranged on the lifting guide rail one 81.

[0050] The supporting block 83 is arranged on the lifting plate 82, and the conveying belt 84 in the direction of the X-axis guide rail 2 is arranged on the upper end of the supporting block 83.

[0051] In the embodiment, the upper end surface of the supporting block 83 needs to be smaller than the area of the upper and lower end surfaces when the un-welded case is placed, on the one hand, so that the clamping mechanism 9 can clamp the un-welded case, and on the other hand, to avoid heat conduction from the laser welding head 7 to the supporting block 83 when welding, thereby improving the operation safety.

[0052] In the embodiment, specifically, when one of the conveying belts 10 conveys the un-welded case, the lifting plate 82 is controlled to descend by the lifting guide rail one 81 until the upper end surface of the conveying belt 84 is flush with the upper end surface of the conveying belt 10, so that the un-welded case conveyed by the conveying belt 10 can be directly input into the conveying belt 84. When the un-welded case is placed in the middle part of the conveying belt 84, the conveying belt 84 stops running. At this time, the lifting plate 82 is controlled to rise to the clamping area of the clamping mechanism 9 by the lifting guide rail one 81.

[0053] In the embodiment, the clamping mechanism 9 comprises:

[0054] The lifting guide rail two 91 is arranged on the machine table 1, and the rotating motor 92 is arranged on the lifting guide rail two 91.

[0055] The clamping frame 93 is arranged on the rotating motor 92, and the cross-shaped clamping head 94 is arranged on the clamping frame 93.

[0056] In this embodiment, the four clamping heads 94 are arranged to correspond to the four sides of the un-welded case, so as to improve the regularity of each side, and avoid the prior art of first spot welding at the weld seam at certain intervals to fix the side of the case, which often leads to uneven weld seam gap, and when the case needs to be turned over, the supporting mechanism 8 is first detached from the case to provide sufficient space for the clamping mechanism 9 to control the turning of the case, and then the supporting mechanism 8 is used to support the case again to ensure the stability of the welding of the case.

[0057] In this embodiment, the clamping head 94 comprises:

[0058] The push-pull air cylinder 95 is arranged transversely, and the output end is vertically connected with the carrier 96;

[0059] The extension air cylinder 97 is arranged transversely at the two ends of the carrier 96, and the output end is provided with the clamping frame 98, which is provided with the temperature sensing module 99 on the outer side, the adsorption module 910 on the inner side, and the flattening module 911 in the adsorption module 910.

[0060] In this embodiment, the temperature sensing module 99 is used to monitor the temperature generated synchronously with the movement of the laser welding head 7 along the weld seam, that is, two temperature sensing modules 99 parallel to the weld seam are formed on both sides of the weld seam, and the distance between the two temperature sensing modules 99 and the weld seam is the same. During the welding process of the laser welding head 7, the heat generated at the weld seam will spread to the surrounding area. By comparing the temperature of the same position on the two temperature sensing modules 99, if there is a difference, the C-axis motor 5 is fed back and adjusted in time to fine-tune the trajectory during movement along the weld seam, thereby facilitating the formation of high-quality weld seams.

[0061] In this embodiment, the adsorption module 910 is used to adsorb and fix the side of the case close to the weld seam, to strengthen the firmness of the plate surface near the weld seam, and to avoid the deformation of the plate surface caused by heat conduction, which may cause uneven weld seam gap. The flattening module 911 is arranged to move back and forth before the adsorption module 910 is adsorbed and fixed, to flatten and adsorb the plate surface in the direction of the weld seam to limit the deformation of the plate surface, thereby ensuring the regularity of the plate surface and the uniformity of the weld seam gap.

[0062] In this embodiment, the temperature of the adjacent temperature sensing modules 99 in each adjacent clamping head 94 can be compared, and the smaller value of the temperature monitored by the temperature sensing module 99 is dynamically selected and fed back to the C-axis motor 5 to control the laser welding head 7 to rotate to the side with the smaller value.

[0063] In the embodiment, the temperature sensing module 99 monitors the process of the weld seam conducting heat as follows: during the welding of the laser welding head 7 along the weld seam, the heat at the welding point will be transferred to the surrounding, that is, it will be transferred to the welded area behind the welding point and the unwelded area in front of the welding point. The temperature sensing module 99 performs heat pre-monitoring analysis on the proximal unwelded area in front of the welding point. If the temperature of the proximal area in front of the welding point deviates, the temperature sensing module 99 is located at the proximal area with a small deviation value. At this time, it is determined that the side needs to increase a certain amount of heat, and the C-axis motor 5 is fed back to control the laser welding head 7 to rotate to the side with a small deviation value. The analysis and judgment are continuously performed in this way, so as to form a high-quality and uniform weld seam.

[0064] In the embodiment, the temperature sensing module 99 comprises:

[0065] The temperature sensing strip 991 is arranged on the clamping frame 98;

[0066] The temperature sensing unit 992 is vertically and closely arranged on the temperature sensing strip 991, and comprises a sealed box 9921. The sealed box 9921 is provided with a heat conduction sheet 9923 on the box surface. The sealed box 9921 is internally provided with a temperature measuring medium 9922. The sealed box 9921 is provided with a temperature measuring rod 9924 connected with the temperature measuring medium 9922.

[0067] In the embodiment, the heat conduction sheet 9923 is attached to the surface of the case plate. The temperature measuring medium 9922 absorbs the heat of the heat conduction sheet 9923. The temperature data of the temperature measuring medium 9922 is obtained by the temperature measuring rod 9924. The temperature data of the temperature measuring medium 9922 is compared with the temperature data of the temperature sensing unit 992 located in the same layer and adjacent to the temperature sensing unit 992. The temperature sensing unit 992 located in the same layer as the welding point is used to determine the range of the C-axis motor 5 controlling the laser welding head 7 to rotate to the side with a small deviation value. That is, when the temperature of the proximal area in front of the welding point deviates, the C-axis motor 5 is fed back to control the laser welding head 7 to rotate to the side with a small deviation value. The rotation stop judgment condition is that the comparison value of the temperature sensing unit 992 located in the same layer as the welding point is within a certain difference range. Therefore, the C-axis motor 5 is stopped. Therefore, during the welding process of the laser welding head 7, a high-quality and uniform weld seam is formed in a dynamic and micro-adjusted track mode.

[0068] In the embodiment, the temperature sensing strip 991 is provided with a vertical protection plate 993. On the one hand, the protection plate 993 has a protection effect. On the other hand, the protection plate 993 has a constant effect on the temperature of the weld seam area, so that the temperature changes uniformly.

[0069] In the embodiment, the adsorption module 910 comprises:

[0070] The adsorption strip cover 9101 is arranged on the clamping frame 98 and is vertically and parallelly arranged in two groups. The cover opening is provided with a breathable gasket 9102.

[0071] Pump body one 9103 is arranged on the adsorption strip cover 9101 and connected with the inner cavity of the adsorption strip cover 9101.

[0072] In this embodiment, the negative pressure generated by the pump body one 9103 in the inner cavity of the adsorption strip cover 9101 enables the air-permeable gasket 9102 to be adsorbed and fixed on the side surface of the case.

[0073] In this embodiment, the adsorption strip cover 9101 is respectively provided with a positioning cylinder 9104 at the upper end and the lower end, and the output end of the positioning cylinder 9104 is provided with a sealing plug 9105 transversely arranged in the inner cavity of the adsorption strip cover 9101.

[0074] In this embodiment, when the length of the adsorption strip cover 9101 is greater than the height of the case when placed, the position of the sealing plug 9105 in the inner cavity of the adsorption strip cover 9101 is adjusted by the positioning cylinder 9104, so that the distance between the two sealing plugs 9105 is equal to the height of the case when placed, so that the air-permeable gasket 9102 exposed outside the side surface of the case plays a blocking role, thereby improving the adsorption strength.

[0075] In this embodiment, the leveling module 911 includes:

[0076] Lifting guide rail three 9111 is arranged on the clamping frame 98 and located between the adsorption strip covers 9101;

[0077] Square shell cover 9112 is arranged on the lifting guide rail three 9111, and an air-permeable frame 9113 parallel to the cover opening is arranged in the interior of the square shell cover 9112, four edge ends of the air-permeable frame 9113 are provided with roller shafts 9114 rotating on the square shell cover 9112, and four groups of roller shafts 9114 are externally sleeved with air-permeable belts 9115;

[0078] Pump body two 9116 is arranged on the side away from the cover opening of the square shell cover 9112 and connected with the inner cavity of the square shell cover 9112.

[0079] In this embodiment, specifically, during the welding process, with the change of the trajectory of the welding point, the square shell cover 9112 is controlled by the lifting guide rail three 9111 to move back and forth by a certain distance with the welding point as the center, and moves with the movement of the welding point, the negative pressure is generated in the inner cavity of the square shell cover 9112 by the pump body two 9116, so that the air-permeable belts 9115 are adsorbed and pulled in the rolling mode on the side surface of the case, thereby maintaining the leveling treatment of the plate surface area where heat is continuously transferred, avoiding the deformation of the plate surface, and ensuring that the welding gap maintains a uniform state.

[0080] In the specific implementation, the working process is as follows:

[0081] First step: the unwelded computer case is transported to the working area of the supporting mechanism 8 by one of the conveyors 10, the lifting guide rail one 81 of the supporting mechanism 8 is lowered, the upper surface of the conveyor belt 84 is flush with the conveyor 10, the case is smoothly transferred to the conveyor belt 84 of the supporting mechanism 8, the conveyor 10 stops after transporting the case to the middle preset position, then the lifting guide rail one 81 drives the supporting plate 82 to rise, the case is lifted to the working height of the clamping mechanism 9;

[0082] Second step: the four clamping heads 94 are driven by the push-pull cylinder 95 to approach the case from four directions synchronously, the suction module 910 is started, the pump body one 9103 generates negative pressure in the suction cover 9101, the area of each side plate of the case near the to-be-welded weld is firmly adsorbed by the air-permeable gasket 9102, the position of the sealing plug 9105 is adjusted by the positioning cylinder 9104, the suction force can be accurately matched with cases of different heights, and the suction force is optimized;

[0083] On the basis of suction fixation, the flattening module 911 starts to work, the lifting guide rail three 9111 drives the square cover 9112 to move back and forth in a small range along the weld direction, and the pump body two 9116 works, so that the air-permeable belt 9115 is tightly attached to the plate surface and rolls under negative pressure, dynamically adsorbs, pulls and rolls the area near the weld, and can eliminate the initial unevenness or residual stress of the plate, so that the gap between the welds is uniform and the plate surface is regular during subsequent welding.

[0084] Third step: the initial path of the laser welding head is planned, the laser welding head is driven by the five-axis linkage of the X-axis guide rail 2, the Y-axis guide rail 3, the Z-axis guide rail 4, the C-axis motor 5 and the B-axis motor 6 to accurately move to the starting point of the weld, and the posture is adjusted as follows: the vertical plane where the laser beam is located is parallel to and centered on the two seam surfaces of the weld.

[0085] Welding starts, the laser welding head moves along the preset track, and the intelligent feedback link starts to work: the temperature sensing modules symmetrically arranged on both sides of the weld start to work in real time, the heat conduction sheet 9923 is attached to the plate surface, the temperature measuring medium 9922 absorbs heat, and the temperature measuring rod 9924 continuously obtains temperature data.

[0086] Dynamic trajectory correction: compare the temperature sensing units 992 on both sides of the weld, when the temperature difference between the two sides is detected (indicating uneven heat conduction), an instruction is immediately sent to the C-axis motor 5 to slightly deflect the laser welding head 7 to the side with lower temperature to increase the heat input of the side. This correction is a continuous closed-loop process: monitoring (temperature sensing module) → comparison and judgment → correction (C-axis adjustment), and the stop condition of the correction is that the temperature difference between the temperature sensing units 992 on the same layer on both sides returns to the preset balanced range.

[0087] Fourth step: when welding different sides of the case, the lifting guide rail 81 of the support mechanism 8 is lowered, so that the case is completely supported by the clamping mechanism 9, the rotating motor 92 drives the clamping frame 93 and the case firmly adsorbed to overturn as a whole, the support mechanism 8 is raised again to support the case to enhance stability, repeat the flattening of the second step and the intelligent welding process of the third step until all the preset welds are welded;

[0088] Fifth step: after all the welding is completed, the clamping mechanism 9 is loosened, the support mechanism 8 is lowered, the welded case is placed on another conveying belt 10, and it is sent out of the working area to complete a complete working cycle.

[0089] In this embodiment, through the real-time temperature field symmetry perception welding track dynamic adaptive control, through the high-precision five-axis linkage system to ensure the flexibility of welding execution, through the clamping and flattening integrated mechanism to ensure the prerequisite for welding (uniform gap), the heat distribution in the welding process is monitored in real time and symmetrically by the temperature sensing array, the monitoring data is used to dynamically and slightly adjust the laser beam pointing, and the welding unevenness caused by the micro unevenness of the plate, the slight deviation of the assembly or the difference in heat conduction is compensated in real time, so as to fundamentally guarantee the high quality, high consistency and low deformation of the welding seam of the thin plate structure such as the computer case.

[0090] The above is only a preferred specific embodiment of the application, but the protection scope of the application is not limited thereto, any person skilled in the art in the technical range disclosed by the application can make equivalent replacement or change according to the technical scheme and the inventive concept of the application, which should be covered in the protection scope of the application.
