[0054] Reference Figures 1-9 This invention proposes an automatic welding device 1000, comprising:

[0055] Rack 10;

[0056] The transfer mechanism 20 is located on the frame 10. The transfer path of the transfer mechanism 20 passes through the loading station 11 and the processing station 12 in sequence, and is used to transport the housing 80 from the loading station 11 to the processing station 12.

[0057] A feeding mechanism 30 is provided at the feeding station 11 and is used to feed the housing 80 to the feeding station 11.

[0058] A material handling mechanism 40, located on one side of the processing station 12, is used to transport the workpiece 90 into the lens groove 81 of the housing 80 located at the processing station 12; and

[0059] The processing mechanism 50 is located at the processing station 12 and is used to weld the workpiece 90 into the lens groove 81 of the housing 80.

[0060] The automatic welding equipment 1000 of this invention includes a frame 10, a transfer mechanism 20, a loading mechanism 30, a picking mechanism 40, and a processing mechanism 50. The loading mechanism 30 transports the tablet computer casing 80 from the production line to the loading station 11. The transfer mechanism 20, mounted on the frame 10, transports the casing 80 from the loading station 11 to the processing station 12. The picking mechanism 40 transports the workpiece 90 to the lens groove 81 of the casing 80 located at the processing station 12. The processing mechanism 50 welds the workpiece 90 into the lens groove 81 by emitting a high-energy laser beam. The automatic welding equipment 1000 achieves fully automatic loading and welding, replacing manual loading and improving the processing efficiency of the casing 80.

[0061] The loading mechanism 30 loads the housing 80 to the loading station 11. Under the transport of the transfer mechanism 20, the housing 80 at the loading station 11 is transported to the processing station 12. The picking mechanism 40, located on one side of the processing station 12, transports the workpiece 90 into the lens slot 81 of the housing 80 at the processing station 12. The processing mechanism 50 is a laser welding device that welds the workpiece 90 into the lens slot 81 using a high-energy laser beam. The laser welding device also includes a CCD module for positioning the workpiece 90 to improve the accuracy of the welding point. The transfer mechanism 20 also includes a fixing component. When the housing 80 is transported to the processing station 12, the fixing component can fix the housing 80 on the processing station 12 to prevent the housing 80 from moving or shaking, which could lead to processing deviations. The separate arrangement of the loading station 11 and the processing station 12 avoids interference between the loading mechanism 30, the processing mechanism 50, and the picking mechanism 40, improving the stability of the internal structure of the automatic welding equipment 1000.

[0062] Reference Figures 1-8 In one embodiment of the present invention, the material handling mechanism 40 includes:

[0063] Orientation fixture 41 is provided on the frame 10 and located on one side of the processing station 12. The upper surface of the orientation fixture 41 is provided with orientation groove 411 for achieving precise orientation of workpiece 90.

[0064] A first material handling assembly 42, disposed on one side of the directional clamp 41, is used to transport the workpiece 90 to the directional groove 411; and

[0065] The second material handling component is located on one side of the orientation fixture 41 and is used to transport the orientation workpiece 90 from the orientation groove 411 to the lens groove 81 of the housing 80 located at the processing station 12.

[0066] In one embodiment of the present invention, since the shape and volume of the workpiece 90 are not fixed, the workpiece 90 can be a block workpiece 90, a strip workpiece 90, or an L-shaped workpiece 90. The shape and volume of the workpiece 90 are not limited here. In order to ensure that the workpieces 90 installed in the lens slot 81 are all facing the same direction for easy processing, the workpieces 90 can be oriented before being installed in the lens slot 81.

[0067] The first material handling component 42 grips the workpiece 90 and transports it into the orientation groove 411 of the orientation fixture 41. The shape and volume of the orientation groove 411 are not fixed; a corresponding orientation fixture 41 is set individually for each type of workpiece 90 to be processed, so that the orientation groove 411 is adapted to the corresponding workpiece 90. The orientation groove 411 is used to accurately orient the workpiece 90. The second material handling component transports the oriented workpiece 90 into the lens groove 81, so that all workpieces 90 in the lens groove 81 are oriented in the same direction, improving welding accuracy.

[0068] The first and second picking components can be robotic arms or vacuum suction cups; the type and structure of the first picking component 42 are not limited here. Both the first and second picking components include a CCD module, which can perform visual positioning of the workpiece 90 to be picked up.

[0069] Reference Figures 1-8 In one embodiment of the present invention, the material handling mechanism 40 includes a flexible vibrating plate 44, which is disposed on the frame 10. The flexible vibrating plate 44 contains a plurality of workpieces 90 and is used to achieve the initial orientation of the workpieces 90.

[0070] The first material handling component 42 transports the workpiece 90 from the flexible vibratory plate 44 to the directional groove 411.

[0071] In one embodiment of the present invention, the workpiece 90 to be processed is loaded into a flexible vibratory feeder 44. The flexible vibratory feeder 44 can initially orient the workpiece 90 to facilitate the first material handling component 42 in grasping the workpiece 90. The first material handling component 42 includes a vision component for locating the initially oriented workpiece 90 and transporting it into the orientation groove 411 for precise orientation. For workpieces 90 with complex structures, the flexible vibratory feeder 44 can position the workpieces 90 with the same gripping position facing the same direction to facilitate the gripping by the first material handling component 42.

[0072] ReferenceFigure 8 In one embodiment of the present invention, the material handling mechanism 40 further includes a turntable 45, which is rotatably mounted on the frame 10. The number of directional clamps 41 is plurality of, and the plurality of directional clamps 41 are arranged at intervals along the circumference of the turntable 45.

[0073] In one embodiment of the present invention, to avoid interference between the first material handling component 42 and the second material handling component when the first material handling component 42 places the workpiece 90 into the orientation groove 411, and to improve material handling efficiency, a turntable 45 is provided between the first material handling component 42 and the second material handling component. The turntable 45 is provided with a plurality of orientation clamps 41, which are spaced apart circumferentially along the turntable 45. The first material handling component 42 loads the workpiece 90 into the orientation clamp 41 on the turntable 45 near the first material handling component 42. The turntable 45 rotates, causing the orientation clamp 41 to rotate to a position close to the second material handling component and stop rotating. The second material handling component removes the workpiece 90 from the orientation groove 411 of the orientation clamp 41 and transports it to the lens groove 81 for processing. The arrangement of multiple orientation clamps 41 reduces the time required for the first material handling component 42 and the second material handling component to wait for the orientation clamps 41 to reach their positions, thereby improving processing efficiency.

[0074] Reference Figures 1-7 In one embodiment of the present invention, the automatic welding equipment 1000 further includes a limiting mechanism 60, which is disposed on one side of the processing station 12 and is used to limit the workpiece 90 that is installed in the lens groove 81 of the housing 80.

[0075] In one embodiment of the present invention, in order to ensure that the housing 80 after welding the workpiece 90 meets the production standards, the workpiece 90 needs to be limited after being installed in the positioning groove to prevent it from shaking or moving during the welding process, which would cause the welding with the housing 80 to be skewed, making it impossible for the lens to be installed into the completed lens groove 81. The setting of the limiting mechanism 60 improves the product qualification rate.

[0076] Reference Figures 1-7 In one embodiment of the present invention, the limiting mechanism 60 includes:

[0077] Limit drive component 61; and

[0078] The limiting component 62 is disposed at one end of the limiting drive member 61. The limiting drive member 61 can drive the limiting component 62 to extend into the lens groove 81 to limit the workpiece 90 installed in the lens groove 81; or

[0079] The limiting drive 61 can drive the limiting component 62 to extend out of the lens groove 81 to release the welded workpiece 90.

[0080] In one embodiment of the present invention, the limiting mechanism 60 includes a limiting drive member 61 and a limiting component 62. The limiting drive member 61 can drive the limiting component 62 to extend into the lens groove 81, limiting the workpiece 90 installed in the lens groove 81; the limiting drive member 61 can also drive the limiting component 62 to extend out of the lens groove 81 to release the welded workpiece 90. The setting of the limiting component 62 improves the machining accuracy of the housing 80, thereby improving the product qualification rate.

[0081] Reference Figures 1-7 In one embodiment of the present invention, the limiting component 62 includes:

[0082] Connector 621, wherein connector 621 is connected to limit drive member 61;

[0083] Claw 622, the claw 622 being used to confine the workpiece 90 within the lens groove 81; and

[0084] A buffer 623 is located between the connector 621 and the pressure claw 622. One end of the buffer 623 elastically abuts against the connector 621, and the other end of the buffer 623 elastically abuts against the pressure claw 622.

[0085] The limiting drive member 61 can drive the pressure claw 622 to descend along the height direction of the frame 10 to extend into the lens groove 81 to limit the workpiece 90, or drive the pressure claw 622 to rise along the height direction of the frame 10 to extend out of the lens groove 81 to release the workpiece 90.

[0086] In one embodiment of the present invention, the limiting drive member 61 can drive the connecting member 621 to move. A buffer member 623 is provided between the connecting member 621 and the pressure claw 622. The buffer member 623 prevents the connecting member 621 or the pressure claw 622 from damaging the housing 80 or the workpiece 90, thus avoiding product defects. The buffer member 623 can be a spring, rubber, or other elastic element; the material and type of the buffer member 623 are not limited here. The buffer member 623 prevents the housing 80 or the workpiece 90 from being damaged by the limiting component 62, reducing the product defect rate and improving the product pass rate.

[0087] Reference Figures 1-7 In one embodiment of the present invention, the pressure claw 622 has a through-hole 6221 at one end away from the connector 621, and a first notch 6222 and a second notch 6223 through the limiting hole 6221 are provided on the side of the end away from the connector 621, with the first notch 6222 and the second notch 6223 being disposed opposite to each other;

[0088] The pressure claw 622 extends into the lens groove 81. The side of the pressure claw 622 with the first notch 6222 abuts against the inner wall of the lens groove 81, so that the inner wall of the lens groove 81 and the limiting hole 6221 form a limiting space 6224. The material handling mechanism 40 transports the workpiece 90 into the limiting space 6224.

[0089] The limiting component 62 further includes a limiting slider 6225, which passes through the second notch 6223 and is movably configured to abut the workpiece 90 in the limiting space 6224 against the inner wall of the lens groove 81 or to release the workpiece 90 in the limiting space 6224.

[0090] In one embodiment of the present invention, before the workpiece 90 is inserted into the lens groove 81, the position of the workpiece 90 needs to be positioned to improve processing accuracy. Specifically, the pressure claw 622 extends into the lens groove 81, and the pressure claw 622 and the inner wall of the lens groove 81 form a limiting space 6224. The second material handling assembly transports the workpiece 90 into the limiting space 6224, and the limiting slider 6225 locks the workpiece 90 within the limiting space 6224, allowing the processing mechanism 50 to weld the workpiece 90 and the housing 80. The setting of the limiting space 6224 improves the processing accuracy of the product.

[0092] Feeding drive component 31; and

[0093] The feeding component 32 is located at one end of the feeding drive 31. The feeding drive 31 can drive the feeding component 32 to grab the housing 80 from the production line and feed it to the feeding station 11.

[0094] In one embodiment of the present invention, the feeding drive 31 can drive the feeding assembly 32 to grab the housing 80 from the production line and feed it to the feeding station 11. Compared with the existing solution of manually handling the housing 80 from the production line to the feeding station 11, the setting of the feeding assembly 32 improves the processing efficiency of the product.

[0095] The loading component 32 can be a robotic arm or a vacuum suction cup; the type and structure of the loading component 32 are not limited here.
