Description

Technical Field

[0001] The invention relates to welding equipment, and in particular to welding equipment and a control method for a car sunroof. Background Art

[0002] With the rapid development of the automobile industry and the increasing demand of consumers for automobile comfort, automobile sunroofs have gradually become an important configuration of modern vehicles. The frame structure of an automobile sunroof is usually rectangular, mainly composed of two long plates and two short plates connected by splicing and welding processes. The precision and efficiency of its splicing and welding directly affect the overall quality and production efficiency of the automobile sunroof. In the actual production process, in order to meet the needs of mass production, the welding equipment of the automobile sunroof frame needs to have efficient and stable welding capabilities to ensure the fit and welding strength of the weld, while improving production efficiency and reducing manufacturing costs.

[0003] Traditional automobile sunroof welding equipment generally adopts a single weld welding method, that is, only one weld can be completed at a time. The rectangular automobile sunroof frame is composed of two long plates and two short plates, with a total of four joint welds. This requires traditional equipment to go through four welding processes to complete the welding of the entire frame, and the welding efficiency is low. In order to solve this problem, relevant manufacturers have developed a welding device that can weld four joint welds at the same time. This welding device has a magnetic suction device for fixing the short plate and a driving component for driving the long plate to move and fit with the short plate, so as to achieve rapid splicing and welding of the short plate and the long plate.

[0004] However, since the two short plates may have some slight deviation in their posture during the placement process, the two short plates will be restricted on the material placement plane of the welding table, and there will be a small non-parallel gap between the first joint surface of the two short plates and the second joint surface of the long plate. In addition, because the movement trajectory of the long plate is restricted to linear, during the welding process, the second joint surface of the long plate and the first joint surface of the short plate are difficult to completely fit together when they are joined, resulting in a gap in the joint seam, which affects the welding quality. Therefore, it is urgent to propose a welding device to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a welding device which improves the welding quality by adding a magnetic suction component and a controllable vacuum adsorption and driving component to ensure the positioning accuracy of short plates and the splicing accuracy of long plates.

[0023] The second magnetic attraction component is arranged in the welding table. The second magnetic attraction component generates a magnetic field in a controlled manner to apply a magnetic attraction force to the long board after the second joint surface of the long board is attached to the first joint surface of the short board, so as to limit the movement of the long board.

[0024] A controller is connected to the soldering station, the first magnetic attraction component, the second magnetic attraction component and the clamping mechanism to control the operation of the soldering station, the first magnetic attraction component, the second magnetic attraction component and the clamping mechanism.

[0025] In particular, a control method for a tailor-made welding device as described above comprises: The short boards placed at the two first pre-positioning areas and the long boards placed at the two second pre-positioning areas are moved to the two first target positions and the two second target positions of the material placement plane respectively by the clamping mechanism.

[0026] A magnetic field is generated at the two first target positions by the two first magnetic attraction components, so as to adsorb the two short plates at the two first target positions respectively.

[0027] The two first driving ends drive the two first vacuum adsorption parts to move relative to each other, so that the long board adsorbed by the two first vacuum adsorption parts moves toward the short board by the target length, so that the second joint surface of the long board fits with the first joint surface of the short board.

[0032] If the first sensor detects that the change in the force state of the first driving end is different from the change in the force state of the first driving end when the first vacuum suction component and the long board slide relative to each other, the vacuum generator is used to release the first vacuum suction component from the long board and stop the first driving end from moving.

[0033] Preferably, the tailor-made welding equipment further comprises: The second sensor is arranged at the first adsorption component to detect the pressure value borne by the first vacuum adsorption component during the process of the second jointing surface of the long board and the first jointing surface of the short board being joined together.

[0035] The beneficial effects of the embodiments of the present invention are as follows: The welding equipment, by adopting the technical means of magnetically fixing the short plate with the first magnetic attraction component, can limit the short plate to the first target position of the material loading plane, thereby realizing the precise positioning of the short plate, and further adopting the technical means of adsorbing the long plate with the first vacuum adsorption component and moving it along the first direction through the first driving end, and combining it with the elastic deformation characteristics of the first vacuum adsorption component, can effectively solve the problem of poor fitting caused by the tiny non-parallel gap between the first joining surface of the short plate and the second joining surface of the long plate when the long plate and the short plate are joined together, thereby realizing a high-fitting joining effect between the long plate and the short plate.

[0036] The control method of the welding equipment adopts a technical means of using a first sensor to detect the change of the force state during the movement of the first driving end, and judging whether the long plate and the short plate are fitted or slipped according to the change of the force state. Therefore, it effectively solves the problem of damage to the first vacuum adsorption part due to insufficient fitting force or excessive movement of the long plate during the movement, thereby achieving the technical effect of precise fitting of the long plate and the short plate.

[0046] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood by specific circumstances.

[0047] A preferred embodiment of the present application provides a welding device, including a welding mechanism (not shown in the figure), which is a welding mechanism used for traditional automobile sunroof welding and need not be elaborated here. The welding mechanism is used to weld the assembled automobile sunroof assembly 10, wherein the automobile sunroof assembly 10 generally includes two long plates 110 and two short plates 120.

[0048] Specifically, the long board 110 and the short board 120 are both rectangular, the long side direction of the long board 110 corresponds to its own length direction, and the short side direction of the rectangular long board 110 corresponds to its own width direction. Similarly, the long side direction and short side direction of the short board 120 also correspond to their own length direction and width direction respectively.

[0049] like Figures 1 to 4 and Figure 6As shown, the welding equipment includes a welding station 20, a first magnetic attraction component and a clamping mechanism 40, wherein the welding station 20 includes a material placement plane 210, and the material placement plane 210 includes two first target positions 211 and two second target positions 212, the two first target positions 211 are used to place two short plates 120, and the short plates 120 at the two first target positions 211 are parallel and the ends are flush, and the ends of the short plates 120 are first joint surfaces 121, and the two second target positions 212 are used to place two long plates 110 ... The long plates 110 at the two second target positions 212 are parallel and respectively located on both sides of the short plate 120, the sides of the two long plates 110 facing each other are the second joint surfaces 111, and the long side direction of the long plate 110 at the second target position 212 is perpendicular to the long side direction of the short plate 120 at the first target position 211, when the short plate 120 and the long plate 110 are respectively at the first target position 211 and the second target position 212, there is a preset distance a between the first joint surface 121 and the second joint surface 111. The first magnetic attraction component is disposed in the welding station 20, and the first magnetic attraction component is controlled to generate a magnetic field at the first target position 211, so as to apply a magnetic attraction force to the short plate 120 at the first target position 211 when in a working state. The clamping mechanism 40 includes two first adsorption components 410, and the two first adsorption components 410 are controlled to move relative to each other or move away from each other, and the moving direction of the two first adsorption components 410 is defined as a first direction. The first adsorption component 410 includes a first driver 411 and a first vacuum adsorption component, wherein the first driver 411 includes a first driving end 4111, and the first driving end 4111 is controlled to move along the first direction, and the moving direction of the first driving end 4111 is parallel to the long side direction of the short plate 120 located at the first target position 211, and the first vacuum adsorption component 412 is controlled to be adsorbed on the long plate 110, and the first vacuum adsorption component 412 is connected to the first driving end 4111 to move with the first driving end 4111, and the first vacuum adsorption component 412 is configured to undergo elastic deformation when the first mating surface 121 of the long plate 110 abuts against the second mating surface 111 of the short plate 120.

[0050] When the welding equipment is in working state, the first magnetic attraction component applies magnetic attraction force to the short plate 120 at the first target position 211 to limit the short plate 120 at the first target position 211, and the first vacuum adsorption component 412, driven by the first driving end 4111, drives the long plate 110 located at the second target position 212 and adsorbed to move toward the short plate 120 located at the second target position 212, and the moving distance of the first driving end 4111 is the target length, and the target length is greater than the preset spacing, so that the second mating surface 111 of the long plate 110 is in contact with the first mating surface 121 of the short plate 120 located at the first target position 211.

[0051] Specifically, the two first target positions 211 and the two second target positions 212 are embodied as rectangular frames on the loading plane 210, and the size of the first target position 211 should be slightly larger than the size of the short board 120 so that the short board 120 can be accommodated within the first target position 211. Similarly, the size of the second target position 212 should also be slightly larger than the size of the long board 110. Moreover, when the short board 120 and the long board 110 are transferred to the first target position 211 and the second target position 212 respectively, the long side and the short side of the short board 120 should be approximately parallel to the length direction and the width direction of the first target position 211, respectively. Similarly, the long side of the long board 110 and the short board 120 should also be approximately parallel to the length direction and the width direction of the second target position 212, respectively.

[0052] The welding mechanism (not shown in the figure) is used to weld the joint seams of the long plate 110 and the short plate 120 after they are assembled. The welding mechanism adopts the welding device used for traditional automobile sunroof welding, which will not be described in detail here.

[0053] The first magnetic attraction component is arranged inside the soldering station 20, specifically, it should be located directly below the first target position 211, and the number of the first magnetic attraction components should be two, corresponding to the two first target positions 211, and the first magnetic attraction component can generate a magnetic field in a controlled manner. When in working state, the first magnetic attraction component generates a magnetic field to fix the short plate 120 at the first target position 211 to prevent its position from shifting. The first magnetic attraction component can be embodied as an electromagnet in a specific manner. The electromagnet is a mature prior art and will not be elaborated here.

[0054] The first driver 411 includes a first driving end 4111, which can move along a first direction (a direction perpendicular to the first joint surface 121) and can be controlled to achieve relative or reverse movement. The first driver 411 can be specifically embodied as an electric cylinder controlled by a servo motor.

[0055] The first vacuum adsorption component 412 can be connected to the first driving end 4111 through a mounting bracket 420 and other mechanisms (not shown in the figure) so that the first vacuum adsorption component 412 moves with the first driving end 4111, and the first vacuum adsorption component 412 adsorbs the long board 110 and makes the long board 110 move with the first driving end 4111. The first vacuum suction component 412 is specifically embodied as a vacuum suction cup. Since the vacuum suction cup has good elastic deformation performance, when the second joint surface 111 of the long plate 110 abuts the first joint surface 121 of the short plate 120, the elastic deformation of the vacuum suction cup can compensate for the excessive displacement of the long plate 110 described later, and with the cooperation of the excessive displacement and the elastic deformation performance of the vacuum suction cup, the adaptive offset of the second joint surface 111 of the long plate 110 and the first joint surface 121 of the short plate 120 after the abutment is achieved, so that the second joint surface 111 of the long plate 110 is as close to the first joint surface 121 of the short plate 120 as possible, thereby reducing the joint seam and reducing the impact on the welding quality.

[0056] After the short plate 120 and the long plate 110 are transferred to the first target position 211 and the second target position 212 respectively, the first magnetic attraction component is activated to generate a magnetic field to apply a magnetic attraction force to the short plate 120, so as to ensure that the short plate 120 remains stable at the first target position 211. The first vacuum adsorption member 412 of the clamping mechanism 40 is adsorbed on the long plate 110, and the long plate 110 is driven to move toward the direction close to the short plate 120 by controlling the first driving end 4111. The moving direction of the first driving end 4111 should be parallel to the long side direction of the first target position 211 (i.e., parallel to the long side direction of the short plate 120), and the moving distance of the first driving end 4111 is the target length, which is greater than the preset spacing, so that the long plate 110 located at the second target position 212 moves in the first direction The distance is the target length, thereby ensuring that the second joint surface 111 of the long plate 110 is in contact with the first joint surface 121 of the short plate 120, so that the gap between the joint surfaces is reduced as much as possible, providing a high-precision foundation for subsequent welding.

[0057] Furthermore, the welding equipment in the present application can also be used for other rectangular or polygonal frame components that require multilateral welding, such as door frames, window frames, etc.

[0058] In this embodiment, by adopting the technical means of magnetically fixing the short plate 120 by the first magnetic attraction component, the short plate 120 can be restricted to the first target position 211 of the loading plane 210, thereby achieving precise positioning of the short plate 120, and further adopting the technical means of using the first vacuum adsorption component 412 to adsorb the long plate 110 and move it along the first direction through the first driving end 4111, and combining it with the elastic deformation characteristics of the first vacuum adsorption component 412, it can effectively solve the problem of poor fitting caused by the slight non-parallel gap between the first joining surface 121 of the short plate 120 and the second joining surface 111 of the long plate 110 when the long plate 110 and the short plate 120 are spliced ​​together, thereby achieving a high-fitting splicing effect between the long plate 110 and the short plate 120.

[0059] Before the sunroof assembly 10 (two long plates 110 and two short plates 120) is transferred to the welding station 20, the two long plates 110 and the two short plates 120 need to be pre-positioned. Figure 5 As shown, in some embodiments, the tailor-made welding apparatus further includes a pre-positioning station 30 .

[0060] A positioning plane 310 is constructed on the pre-positioning platform 30, and the positioning plane 310 is used to place the sunroof assembly 10. The pre-positioning platform 30 also includes a plurality of first positioning members 320 and a plurality of second positioning members 330. The plurality of first positioning members 320 are installed on the pre-positioning platform 30 to enclose and form two first pre-positioning areas at the positioning plane 310. The shape and size of the first pre-positioning area are the same as the shape and size of the short board 120, and the first pre-positioning area is configured so that when the two short boards 120 are respectively placed in the two first pre-positioning areas, the two short boards 120 are arranged in parallel, and the first joint surfaces 121 of the two short boards 120 are flush. Specifically, the first pre-positioning area is embodied as a rectangular outline on the positioning plane 310, which should be a rectangular cylindrical space, which is used to place the short board 120 and limit the movement of the short board 120 in the plane.

[0061] The positioning plane 310 is a horizontally placed plane used to support the placement of the long board 110 and the short board 120 to ensure the position accuracy of the components.

[0062] A plurality of second positioning members 330 are arranged at the pre-positioning platform 30, and the plurality of second positioning members 330 are installed at the pre-positioning platform 30 to enclose and form two second pre-positioning areas, and the shape and size of the second pre-positioning areas are the same as the shape and size of the long board 110, and the second pre-positioning areas are configured so that when the two long boards 110 are respectively placed in the two second pre-positioning areas, the two long boards 110 are arranged in parallel, and the distance between the second joint surface 111 of the long board 110 and the first joint surface 121 of the short board 120 placed in the first pre-positioning area is a preset distance. Specifically, the second pre-positioning area is embodied as a rectangular outline on the positioning plane 310, which should specifically be a rectangular cylindrical space, which is used to place the long board 110 and limit the movement of the long board 110 in the plane. Among them, the preset spacing is the shortest distance between the first pre-positioning area and the second pre-positioning area, and this distance is usually determined by the first positioning member 320 and the second positioning member 330. In a specific manner, the first positioning member 320 and the second positioning member 330 can be embodied as positioning pins, and the diameters of the positioning pins corresponding to the first positioning member 320 and the second positioning member 330 are the same. At this time, the diameter of the positioning pin is the preset spacing.

[0063] It should be noted that in order to transfer the pre-positioned long plates 110 and short plates 120, the preset spacing needs to be slightly larger than the diameter of the positioning pins, usually wire to wire, so as to remove the plates in the first pre-positioning area and / or the second pre-positioning area, and it can be understood that the gap of the joints to be welded between the plates is much larger than wire to wire, so the preset spacing slightly larger than the diameter of the positioning pins will not affect the pre-positioning.

[0064] The two short boards 120 are placed in the two first pre-positioning areas on the pre-positioning table 30, respectively. The first positioning member 320 ensures that the first joint surfaces 121 of the two short boards 120 are approximately parallel and the ends are approximately flush through physical limiting, where the ends refer to the width of the short boards 120 on the corresponding side. The two long boards 110 are placed in the two second pre-positioning areas on the pre-positioning table 30, respectively. The two second positioning members 330 ensure that the second joint surfaces 111 of the long boards 110 are approximately parallel and maintain a consistent preset spacing with the first joint surfaces 121 of the short boards 120 through physical limiting. Through the precise layout of the first positioning member 320 and the second positioning member 330, the long boards 110 and the short boards 120 can achieve high precision in relative position in the pre-positioning stage, reducing the need for additional adjustments when subsequently transferred to the welding station 20. After completing the pre-positioning, the clamping mechanism 40 or other auxiliary equipment accurately transfers the short plate 120 and the long plate 110 from the pre-positioning table 30 to the material placement plane 210 of the welding table 20, maintaining the parallelism and preset spacing formed in the pre-positioning stage, and directly performing subsequent welding operations.

[0065] In this embodiment, firstly, since the technical means of forming the first pre-positioning area and the second pre-positioning area by the first positioning member 320 and the second positioning member 330 is adopted, the problem that the long plate 110 and the short plate 120 cannot be accurately parallel positioned before being transferred to the welding station 20 is effectively solved, thereby achieving a high-precision pre-positioning effect of the long plate 110 and the short plate 120. Secondly, since the technical means of maintaining the preset spacing between the long plate 110 and the short plate 120 by the first pre-positioning area and the second pre-positioning area through the limiting structure is adopted, the problem of poor fitting of the long plate 110 and the short plate 120 due to the spacing error before welding is effectively solved, thereby achieving accurate assembly preparation of the welding assembly in the pre-positioning stage. In addition, the modular design of the pre-positioning station 30 is adaptable to a variety of component sizes and shapes, and can flexibly adapt to the production requirements of different products by adjusting the layout of the positioning members, which significantly improves the adaptability and practicality of the equipment. Therefore, through the above technical means, the pre-positioning table 30 of the present invention significantly improves the initial assembly accuracy of the long plate 110 and the short plate 120, reduces the adjustment workload in the subsequent welding stage, and thus improves the overall production efficiency and welding quality.

[0066] In order to transfer the skylight assembly 10 (two long plates 110 and two short plates 120) that has been pre-positioned at the pre-positioning table 30 to the material placement plane 210 of the welding table 20, the clamping mechanism 40 also includes a bracket 420 and a second vacuum adsorption component 430. The bracket 420 is controlled to rise and fall and translate. The first adsorption component 410 is connected to the bracket 420 to move with the bracket 420. The second vacuum adsorption component 430 is controlled to be adsorbed on the short plates 120, and the second vacuum adsorption component 430 is connected to the bracket 420 to move with the bracket 420.

[0067] Specifically, the bracket 420 is connected to the first adsorption component 410 and the second vacuum adsorption component 430, and can be lifted and translated in a controlled manner in the vertical and horizontal directions. The lifting function of the bracket 420 is used to lift the clamped long plate 110 and short plate 120 from the pre-positioning table 30 and move them smoothly to the welding table 20. The translation function of the bracket 420 is used to complete the lateral transfer from the pre-positioning table 30 to the welding table 20. The controlled movement of the bracket 420 is specifically reflected in being driven by a travel mechanism (not shown in the figure), and the travel mechanism includes a cylinder or an electric push cylinder or an electric slide or a robotic arm, etc. The travel mechanism is a mature existing technology and will not be described here.

[0068] When the second vacuum adsorbent 430 is disposed on the bracket 420, it can be controlled to adsorb the short board 120, and the second vacuum adsorbent 430 should be in a relatively static state during the transfer of the short board 120 to ensure that the posture of the short board 120 remains stable during the movement and the relative position with the long board 110 does not change. Similarly, the first vacuum adsorbent 412 should also remain in a relatively static state during the transfer of the long board 110. In summary, the first adsorption assembly 410 works in coordination with the second vacuum adsorbent 430 through the bracket 420 to jointly complete the precise transfer of the entire sunroof assembly 10.

[0069] The transfer of the pre-positioned sunroof assembly 10 comprises the following steps: First, adsorption and initial positioning are required. After the two long plates 110 and the two short plates 120 of the skylight assembly 10 are pre-positioned respectively, the bracket 420 is controlled to be lowered to the pre-positioning platform 30 of the pre-positioning platform 30. The first vacuum adsorption component 412 of the first adsorption component 410 is activated to adsorb the long plate 110. The second vacuum adsorption component 430 is activated at the same time to adsorb the short plate 120 to ensure that the various components of the skylight assembly 10 on the pre-positioning platform 30 are firmly clamped.

[0070] Secondly, vertical lifting is performed. The bracket 420 is raised in a controlled manner to lift the adsorbed long board 110 and short board 120 away from the pre-positioning platform 30 to ensure that the components will not interfere with the positioning parts of the pre-positioning platform 30 during the movement.

[0071] Then, the bracket 420 is moved in a controlled manner along the translation direction to transfer the long plate 110 and the short plate 120 as a whole to the material placement plane 210 of the welding station 20 .

[0072] During the translation process, the first vacuum suction member 412 and the second vacuum suction member 430 always maintain suction on the long board 110 and the short board 120 to ensure that the preset relative position (including parallelism and preset spacing) between the long board 110 and the short board 120 does not shift.

[0073] After the bracket 420 has completed translation, it is controlled to drop to the height of the material placement plane 210 of the welding table 20 and to move in plane, so that the long board 110 and the short board 120 are placed at the second target position 212 and the first target position 211 of the welding table 20 respectively.

[0074] At this time, the first joint surface 121 and the second joint surface 111 of the short plate 120 and the long plate 110 maintain a preset parallel relationship and spacing, providing a high-precision jointing foundation for subsequent welding operations.

[0075] The clamping mechanism 40 is suitable for transferring and positioning components in industrial production lines, and is particularly suitable for high-precision welding of large frames (such as automobile sunroof frames).

[0076] In some scenarios, the lifting and translation functions of the bracket 420 can be realized by a mechanical arm or a multi-degree-of-freedom robot to adapt to a more complex working environment. The second vacuum adsorption member 430 can be replaced by a mechanical clamping device for fixing the short plate 120, which is suitable for components of non-planar or non-magnetic materials.

[0077] This embodiment adopts the technical means of linking the bracket 420 with the first adsorption component 410 and the second vacuum adsorption component 430, so as to effectively solve the problem of insufficient welding accuracy of the long plate 110 and the short plate 120 caused by position offset during the transfer process from the pre-positioning table 30 to the welding table 20, thereby achieving the technical effect of high-precision transfer and stable placement of the long plate 110 and the short plate 120.

[0078] The clamping mechanism 40 is simple in design and highly adaptable. Through the flexible lifting and translation functions of the bracket 420, it can adapt to a variety of frame components of different shapes and sizes, significantly improving the flexibility and practicality of the equipment, while meeting the high-precision production requirements. Therefore, through the above technical means, the clamping mechanism 40 of the welding equipment realizes the precise transfer from the pre-positioning stage to the welding stage, effectively guarantees the welding quality and production efficiency, and further enhances the reliability and consistency of the production of the automobile sunroof assembly 10.

[0079] Furthermore, in order to limit the long plate 110 after the long plate 110 and the short plate 120 are assembled, in some embodiments, the welding equipment also includes a second magnetic attraction component (not shown in the figure), which is arranged in the welding table 20. The second magnetic attraction component generates a magnetic field in a controlled manner to apply a magnetic attraction force to the long plate 110 after the second assembly surface 111 of the long plate 110 and the first assembly surface 121 of the short plate 120 are assembled, so as to limit the movement of the long plate 110.

[0080] Specifically, the second magnetic attraction component is installed inside the welding station 20. When the second joint surface 111 of the long board 110 and the first joint surface 121 of the short board 120 are completely joined, the second magnetic attraction component starts to generate a magnetic field, exerts a magnetic attraction force on the long board 110, and limits the long board 110 by the magnetic attraction force to ensure that it will not move during the welding process. Therefore, the second magnetic attraction component should be installed directly below the long board 110 after the long board 110 is assembled to limit the movement of the assembled long board 110.

[0081] The specific control process of the second magnetic attraction component is as follows: Under the action of the clamping mechanism 40, the long plate 110 is moved to the position of the short plate 120, and the second joint surface 111 of the long plate 110 is fitted with the first joint surface 121 of the short plate 120. At this time, the controller detects that the joint is completed and starts the second magnetic suction component. The second magnetic suction component generates a magnetic field and applies a downward magnetic suction force to the long plate 110, so that the long plate 110 is firmly fixed on the material plane 210, limiting the movement and shaking of the long plate 110, ensuring that the long plate 110 remains stable during the welding process, and avoiding position displacement caused by external force or vibration. After the long plate 110 and the short plate 120 are stably limited, the welding mechanism starts to weld the joint seam of the long plate 110 and the short plate 120. The second magnetic suction component continues to operate throughout the welding process to ensure the relative position of the components during the welding process. After the welding is completed, the controller turns off the second magnetic suction component, the limit of the long plate 110 and the short plate 120 is released, and the welding equipment enters the next production cycle.

[0082] This technical solution is suitable for industrial production scenarios that require components to be stably fixed for a long time, such as high-precision welding of car sunroof frames.

[0083] In some usage scenarios, if the materials of the long board 110 and the short board 120 cannot meet the magnetic attraction requirements, the second magnetic attraction component can be replaced with a mechanical limiting device (such as a clamping mechanism or a hydraulic limiting mechanism) to fix the long board 110 by mechanical force.

[0084] Furthermore, the magnetic attraction of the second magnetic attraction component can be dynamically adjusted by the controller to adapt to the long plate 110 of different materials, thicknesses and shapes, ensuring the effect and stability of the limit. In the case of higher limit accuracy requirements or to avoid interference with the welding process due to magnetic attraction, a non-contact limit solution can be used, such as an electrostatic adsorption device or a pneumatic limit device.

[0085] In this embodiment, firstly, since the second magnetic component is used to magnetically limit the long plate 110, the problem of position displacement of the long plate 110 due to vibration or external force during welding is effectively solved, thereby achieving high stability and high precision of the joint seam between the long plate 110 and the short plate 120 during welding. Secondly, since the magnetic force of the second magnetic component can act on the long plate 110 in real time after the splicing is completed, the problem of the long plate 110 being difficult to stably fix after splicing is effectively solved, thereby achieving accurate positioning and efficient operation of the long plate 110 during welding. This solution replaces the traditional mechanical clamp limit with magnetic limit, reduces physical interference and the use of complex mechanisms, and thus effectively reduces the maintenance cost of the equipment, thereby achieving simplicity and reliability of the equipment design. In addition, this technical solution is suitable for a variety of long plate 110 components of different sizes and shapes, and can adapt to plates of different thicknesses and materials by adjusting the magnetic force, thereby improving the versatility and practicality of the welding equipment.

[0086] In summary, by adding a second magnetic attraction component in the welding table 20, the stability of the long plate 110 and the short plate 120 during the welding process is significantly improved, the reliability of the welding quality is ensured, and the operation process and production efficiency of the equipment are optimized, providing reliable technical guarantee for the efficient production of the automobile sunroof assembly 10.

[0087] Furthermore, in order to control the vacuum degree of the first vacuum suction component 412, in some embodiments, the first suction component 410 also includes a vacuum generator (not shown in the figure), which is connected to the first vacuum suction component 412 through a pipeline, and the vacuum generator operates in a controlled manner to adjust the vacuum degree of the first vacuum suction component 412.

[0088] In order to achieve a better splicing effect when the welding equipment in the present application is used, a control method for the welding equipment is specially proposed. In order to adapt to the control method, the welding equipment also includes a controller, which is connected to the welding station 20, the first magnetic attraction component, the second magnetic attraction component and the clamping mechanism 40 to control the operation of the welding station 20, the first magnetic attraction component, the second magnetic attraction component and the clamping mechanism 40. The control method includes the following steps: The short board 120 placed at the two first pre-positioning areas and the long board 110 placed at the two second pre-positioning areas are moved to the two first target positions 211 and the two second target positions 212 of the material placement plane respectively by the clamping mechanism 40 .

[0089] A magnetic field is generated at the two first target positions 211 by the two first magnetic attraction components, so as to adsorb the two short plates 120 at the two first target positions 211 respectively.

[0090] The two first driving ends 4111 drive the two first vacuum adsorption components 412 to move relative to each other, so that the long board 110 adsorbed by the two first vacuum adsorption components 412 moves toward the short board 120 by the target length, so that the second joint surface 111 of the long board 110 fits with the first joint surface 121 of the short board 120.

[0091] The control method ensures the stability, fit and welding accuracy of the short plate 120 and the long plate 110 by precisely controlling the operation of each component in the device.

[0092] Specific: Transfer and initial positioning of the short board 120 and the long board 110. By controlling the bracket 420 of the clamping mechanism 40, the first vacuum adsorption member 412 adsorbs the long board 110, and the second vacuum adsorption member 430 adsorbs the short board 120. The bracket 420 is raised and lowered in a controlled manner to lift the short board 120 and the long board 110 from the pre-positioning table 30 of the pre-positioning table 30, and then accurately transfers them to the material placement plane 210 of the welding table 20 through a translation motion. The long board 110 and the short board 120 are respectively placed at two first target positions 211 and two second target positions 212 of the welding table 20.

[0093] It should be noted that it is necessary to ensure that the clamping mechanism 40 can firmly adsorb the short board 120 and the long board 110 to prevent displacement during the transfer process, and through the translation and lifting functions of the bracket 420, the short board 120 and the long board 110 are placed at the target position without error.

[0094] Precise fixation of the short board 120. Start the first magnetic attraction component inside the welding station 20 to generate a magnetic field at the first target position 211. The short board 120 is confined to the first target position 211 by magnetic attraction, ensuring that the posture of the short board 120 is consistent with the reference plane of the welding equipment. In addition, the magnetic attraction force of the first magnetic attraction component needs to be strong enough to overcome the gravity and other external forces of the short board 120. Ensure that the long side of the short board 120 is perpendicular to the material placement plane 210 of the welding station 20 to provide a reference for subsequent splicing operations.

[0095] Movement and fitting of the long board 110. Start the first driver 411 to move the first driving end 4111 in the first direction (the direction perpendicular to the first joint surface 121 of the short board 120). The long board 110 adsorbed by the first vacuum adsorption component 412 moves with the first driving end 4111, gradually approaching the short board 120. Until the second joint surface 111 of the long board 110 abuts against the first joint surface 121 of the short board 120. Afterwards, the first driving end 4111 is controlled to move the target length. Because the target length is greater than the preset length, the long board 110 continues to move with the first moving end, which causes the vacuum suction cup to passively undergo elastic deformation. At this time, the posture of the long board 110 can be adaptively adjusted under the cooperation of the over-limit movement and the elastic deformation of the first vacuum adsorption component 412, thereby absorbing slight errors to ensure that the second joint surface 111 of the long board 110 and the first joint surface 121 of the short board 120 fit as closely as possible.

[0096] It should be noted that the driving distance of the first driver 411 must be precisely controlled to ensure that the moving distance is greater than the preset distance but not excessive, so as to achieve seamless fitting. The elastic deformation of the vacuum suction cup needs to be moderate, which can buffer the error and provide sufficient adsorption stability.

[0097] It is understandable that in the above process, the short board 120 and the long board 110 need to have good magnetism or be installed with additional magnetic clamps to adapt to the magnetic suction assembly, and the short board 120 and the long board 110 also need to have a good surface for adsorption.

[0098] This embodiment uses the bracket 420 and the vacuum adsorption member to adsorb the short plate 120 and the long plate 110, and controls the lifting and translation thereof, which effectively solves the problem of positional deviation of the long plate 110 and the short plate 120 from the pre-positioning table 30 to the welding table 20, thereby achieving the technical effect of high-precision transfer and precise placement of the short plate 120 and the long plate 110. In addition, due to the use of the technical means of the first magnetic adsorption component generating a magnetic field at the first target position 211 and magnetically fixing the short plate 120, the problem of the short plate 120 on the welding table 20 being unstable or deviated due to external forces is effectively solved, thereby achieving the stability of the short plate 120 and the reliability of the welding benchmark.

[0099] Furthermore, since the vacuum suction cup in this embodiment can undergo elastic deformation when the long plate 110 and the short plate 120 are joined together, the problem of poor fitting caused by slight position errors during the welding process is effectively solved, thereby improving the joining effect of the long plate 110 and the short plate 120.

[0100] In the above control method, the determination of the target length is an important factor in ensuring the final splicing effect of the long board 110 and the short board 120. The determination of the target length can be obtained by the following steps: First, the initial spacing needs to be determined.

[0101] The diameters of the first positioning member 320 and the second positioning member 330 when they are positioning pins are measured and their values ​​are recorded. This value is the basic parameter of the initial spacing between the long board 110 and the short board 120.

[0102] It is understandable that the reserved clearance required for taking and placing the panels can be increased when necessary, usually by 5 to 10 threads based on the diameter of the positioning pins.

[0103] Next, the elastic range of the first vacuum suction member 412 needs to be calculated.

[0104] The maximum elastic deformation capacity of the vacuum adsorption part can be obtained from the product parameters. For example, the maximum allowable elastic deformation of the vacuum adsorption part of a certain material is 5 mm.

[0105] Determine the safe range of elastic deformation and limit the maximum elastic deformation to 80% based on safety requirements. In other words, multiply the maximum deformation by 0.8 to calculate the elastic range.

[0106] Then, the target length is calculated comprehensively.

[0107] The initial distance is added to the safety elastic range of the first vacuum suction member 412 to obtain a preliminary target length.

[0108] Next, verify the rationality of the preliminary target length.

[0109] The joining state of the long plate 110 and the short plate 120 is simulated in an actual welding device to confirm whether the second joining surface 111 of the long plate 110 and the first joining surface 121 of the short plate 120 can be fitted together without obvious gap when the first driving end 4111 moves the initial target length.

[0110] If the experimental verification finds that the splicing effect is not ideal, the initial spacing or the elastic range of the vacuum adsorption part can be adjusted according to the actual situation, and the target length can be recalculated until the fitting requirements are met.

[0111] Finally, record the final target length.

[0112] The target length finally determined after verification is used as the reference value for equipment control.

[0113] Furthermore, in order to prevent the elastic deformation of the first vacuum adsorption component 412 from exceeding the elastic limit due to excessive movement of the first driving end 4111, in some embodiments, the welding equipment also includes a first sensor (not shown in the figure), which is arranged at the first driving end 4111 of the first driver 411 to detect the stress state of the first driving end 4111 during the movement.

[0114] In the control method, the two first driving ends 4111 drive the two first vacuum adsorbents 412 to move relative to each other, so that the long board 110 adsorbed by the two first vacuum adsorbents 412 respectively moves toward the short board 120 by the target length, so that the second joint surface 111 of the long board 110 fits with the first joint surface 121 of the short board 120, including the following steps: The first driving ends 4111 of the two first adsorption components 410 are moved in opposite directions, and the moving distance of each of the first driving ends 4111 is the target length; Monitoring the change of the force state of the first driving end 4111 by the first sensor; If the first sensor detects that the change in the force state of the first driving end 4111 is consistent with the change in the force state of the first driving end 4111 when the first vacuum adsorption member 412 and the long board 110 slide relative to each other, the first driving end 4111 stops moving; If the first sensor detects that the change in the force state of the first driving end 4111 is different from the change in the force state of the first driving end 4111 when the first vacuum suction component 412 and the long board 110 slide relative to each other, the first vacuum suction component 412 is released from the adsorption on the long board 110 through the vacuum generator, and the first driving end 4111 stops moving.

[0115] Specifically, the first sensor is disposed at the first driving end 4111 of the first driver 411 to detect in real time the force change of the first driving end 4111 in the process of driving the first vacuum adsorption member 412 to drive the long board 110 to move, and provide a feedback signal. In addition, by monitoring the force state, the relative slip point between the first vacuum adsorption member 412 and the long board 110 is determined to prevent the elastic deformation from exceeding the safety range.

[0116] The first driving end 4111 is the moving part of the first driver 411, which directly drives the first adsorption component 410 to move toward the short plate 120 along the first direction, so as to drive the first vacuum adsorption component 412 and the long plate 110 to approach the short plate 120, and finally complete the splicing. The first vacuum adsorption component 412 adsorbs the long plate 110 by vacuum adsorption, and provides elastic deformation to absorb errors during the splicing process to ensure the welding accuracy. The elastic deformation amount shall not exceed its elastic limit, so as not to cause damage to the adsorption component or reduce the welding accuracy.

[0117] The specific control methods are as follows: Initial movement of the long board 110. The first drivers 411 in the two first adsorption components 410 are activated to make their first drive ends 4111 move relatively along the first direction. The long board 110 adsorbed by the first vacuum adsorption component 412 begins to approach the short board 120. The first drive end 4111 is continuously moved until the second joint surface 111 of the long board 110 and the first joint surface 121 of the short board 120 begin to contact, that is, the two ends of the long board 110 and the short board 120 on both sides are in contact.

[0118] Initial fitting and deformation. After the long board 110 and the short board 120 are in contact, the two first driving ends 4111 continue to be controlled to move slowly in relative directions. As the driving ends move, the first vacuum suction member 412 begins to deform elastically to ensure that the joint surface between the long board 110 and the short board 120 gradually fits. The first sensor monitors the force changes of the first driving end 4111 in real time and records the force generated by the vacuum suction cup due to elastic deformation.

[0119] Slip trigger point detection: When the moving distance of the first driving end 4111 reaches near the target length, the elastic deformation of the first vacuum suction member 412 should begin to approach 80% of the elastic limit.

[0120] At this time, the first sensor monitors the stress state of the driving end in real time to determine whether it has reached the critical stress point at which the vacuum adsorption member and the long plate 110 have relative slippage.

[0121] If the force change detected by the first sensor is consistent with the force characteristics when the vacuum suction member slips, the system determines that the assembly of the long board 110 and the short board 120 is completed.

[0122] If the moving distance of the first driving end 4111 reaches the upper limit of the target length, and the first sensor detects that the force change state of the first driving end 4111 does not meet the force change state at the slip trigger point, the movement of the two first driving ends 4111 is stopped immediately or the first vacuum suction component 412 and the long plate 110 are caused to slide relative to each other by controlling the vacuum degree, so as to avoid the elastic deformation of the vacuum suction cup exceeding the limit due to excessive movement.

[0123] After stopping, the second joint surface 111 of the long plate 110 and the first joint surface 121 of the short plate 120 are in a completely fitted state, providing a high-precision joint basis for subsequent welding operations.

[0124] The specific working principle is as follows: The first sensor determines the relative sliding point between the first vacuum adsorption member 412 and the long board 110 in real time according to the change of the force state of the first driving end 4111 during the movement. When the change of the force state meets the sliding trigger feature, the system automatically stops the movement of the first driving end 4111.

[0125] The judgment basis of the slip point refers to the critical point when the adsorption force of the first vacuum adsorption member 412 can no longer maintain the position of the long board 110. At this time, the force on the driving end will suddenly change, and the first sensor can accurately capture this change.

[0126] The system limits the elastic deformation amount through the feedback information detected by the first sensor to ensure that the elastic deformation amount of the first vacuum adsorption component 412 is always less than its elastic limit (usually set to 80% of the limit) to avoid damage to the adsorption component.

[0127] The key aspects of the control method include: Move gradually, and control the first driving end 4111 to move slowly and accurately to avoid the deformation amount exceeding the control range due to too fast movement.

[0128] Real-time detection, the first sensor monitors the stress state throughout the whole process to ensure that the long board 110 will not be displaced or welded unsuccessfully due to excessive or uneven stress during movement.

[0129] Vacuum degree control: when the deformation of the first vacuum adsorption component 412 reaches 80% of the deformation limit, if the first vacuum adsorption component 412 and the long plate 110 are to slide relative to each other, the vacuum degree needs to be reasonably set, and the vacuum degree can be obtained through repeated tests.

[0130] In this embodiment, since the technical means of using the first sensor to monitor the stress state of the first driving end 4111 is adopted, the problem of damage to the adsorption component caused by the excessive elastic deformation of the first vacuum adsorption component 412 is effectively solved, thereby achieving high-precision control of the welding process of the long plate 110 and the short plate 120.

[0131] In order to avoid partial overlap of the edges of the panels after the second joint surface 111 of the long board 110 and the first joint surface 121 of the short board 120 are abutted, due to the height difference between the side of the second joint surface 111 of the long board 110 and the side of the first joint surface 121 of the short board 120. In some embodiments, the welding equipment also includes a second sensor (not shown in the figure), which is arranged at the first adsorption component 410 to detect the pressure value of the first adsorption component 410 after moving the long board 110 to the material placement plane 210. The control method includes: Before the first driving ends 4111 of the two first adsorption components 410 are moved in opposite directions, the bracket 420 is controlled to move downward so that the long plate 110 and the short plate 120 are both in contact with the material placement plane 210 until the real-time pressure value measured by the second sensor is greater than the preset pressure value. The method specifically includes the following steps: The two first adsorption components 410 and the two second adsorption components are moved to the top of the two second pre-positioning areas and the two first pre-positioning areas respectively by controlling the movement of the bracket 420 .

[0132] The support 420 is controlled to move downward, so that each first adsorption assembly 410 and each second adsorption assembly abut against and adsorb each long plate 110 and each short plate 120 respectively.

[0133] The support 420 is controlled to move upward, so that the long board 110 and the short board 120 are separated from the pre-positioning platform 30 .

[0134] The support 420 is controlled to move to the welding station 20 , and the two long plates 110 and the two short plates 120 are respectively located directly above the two second target positions 212 and the two first target positions 211 .

[0135] The support 420 is controlled to move downward, so that each long plate 110 and each short plate 120 abuts against the material placement plane 210 until the pressure value measured by the second sensor is greater than the preset pressure value.

[0136] When the pressure of the second sensor is greater than the preset pressure value, it can be indicated that the side of the long plate 110 facing the welding table 20 is completely in contact with the material placement plane 210 .

[0137] Afterwards, after the side of the long board 110 facing the welding station 20 is completely attached to the material placement plane 210 , a subsequent joining step can be performed to move the second joining surface 111 of the long board 110 toward the first joining surface 121 of the short board 120 .

[0138] Specifically, in order to solve the problem of partial edge overlap caused by the height difference when the long board 110 and the short board 120 are assembled, the present invention introduces a second sensor to detect the bonding state of the long board 110 on the material plane 210, and uses the pressure value as a feedback signal to ensure that the assembly process of the long board 110 and the short board 120 is accurate and correct. The specific control method is as follows: Support 420 lowering and pressure monitoring.

[0139] The control bracket 420 is gradually moved downward to place the long board 110 and the short board 120 on the material placement plane 210 of the welding station 20. The second sensor (installed at the first adsorption component 410) monitors the pressure change of the first adsorption component 410 in real time. When the long board 110 gradually contacts the material placement plane 210, the pressure value begins to increase.

[0140] When the second sensor detects a pressure value greater than the preset pressure value, it indicates that the bottom surface of the long board 110 facing the welding station 20 is completely in contact with the material plane 210. When the long board 110 is not in contact, the bracket 420 continues to move downward to ensure that the overall plane of the long board 110 is completely aligned with the material plane 210.

[0141] Stop the movement of the bracket 420. Once the pressure value exceeds the preset pressure value, the system automatically stops the bracket 420 from descending to avoid component damage or error caused by excessive downward movement.

[0142] In this embodiment, the pressure value is used as the basis for judging the fit, and the second sensor monitors the pressure change of the first adsorption component 410 during the descent of the bracket 420 to judge in real time whether the long board 110 is completely fitted with the material placement plane 210. When the pressure value exceeds the preset value, it indicates that the bottom surface of the long board 110 is in seamless contact with the material placement plane 210 of the welding station 20.

[0143] The preset pressure value can be obtained based on repeated tests, and can ensure that the long board 110 will not be deformed due to excessive pressure when fitting.

[0144] It should be noted that the joining step is only started after the long board 110 is completely aligned with the loading plane 210 , so as to avoid the problem of overlapping edges of the boards or poor alignment caused by the long board 110 not being aligned with the loading plane 210 .

[0145] Furthermore, the second sensor continuously monitors the change in the pressure value, provides real-time feedback during the splicing process of the long board 110 and the short board 120, and dynamically adjusts the operation of the bracket 420 and the driving mechanism to ensure the splicing accuracy.

[0146] In this embodiment, firstly, due to the technical means of using the second sensor to detect the pressure value, the problem of insufficient splicing accuracy caused by the incomplete fit between the long plate 110 and the material placement plane 210 is effectively solved, thereby achieving a high-precision splicing effect between the long plate 110 and the short plate 120. Secondly, by controlling the descending action of the bracket 420 through pressure value feedback, the problem of partial overlap of the edges of the splicing surfaces due to the height difference is effectively solved, thereby achieving a seamless fitting effect of the welding operation. Furthermore, the real-time feedback function of the second sensor ensures that the splicing pressure is dynamically adjusted during the splicing process to meet the fitting requirements of different panels, significantly improving the adaptability and flexibility of the equipment. Furthermore, the determination of the splicing state is automatically controlled by the pressure value without manual intervention, which greatly improves production efficiency and welding quality.

[0147] In summary, by adding a second sensor to detect the pressure value of the long plate 110 on the material plane 210, the present invention can accurately determine the bonding state of the long plate 110, and effectively avoid the local overlap problem caused by the height difference during the welding process by combining the dynamic adjustment mechanism, which significantly improves the splicing accuracy and welding quality. This method is applicable to welding scenarios of various frame structures and provides strong technical support for efficient and high-precision production.
