Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0033] In the embodiments of this application, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0034] Please see Figures 1 to 3This application provides a welding vision module 100, including a rotary table 110, a carrier 120, a ring light source 130, and a first camera 140 arranged sequentially. The rotary table 110 includes a fixed base 111 and a rotating part 112, which can rotate relative to the fixed base 111 about a first axis A1. The carrier 120 includes a tray 121 and a baffle 122. The tray 121 is detachably connected to the rotating part 112, and the baffle 122 is located between the tray 121 and the rotary table 110. In the direction of the first axis A1, the outer edge projection of the baffle 122 covers the outer edge projection of the tray 121. The side of the tray 121 facing away from the baffle 122 has a slot 1211 for placing a workpiece 1. The tray 121 has various specifications, and the shape and / or size of the slot 1211 in different specifications of the tray 121 are different. The ring light source 130 has a ring-shaped light-emitting surface 130a, which faces the carrier 120. The light-incident side of the first camera 140 is positioned facing the inner hole 131 of the ring light source 130.

[0035] Workpiece 1 can be a gold product or a product made of other highly reflective materials. Taking a gold product as an example, gold is a highly reflective material. A gold product may include an upper blank 1a and a lower blank 1b, which can be sheet-like and stacked. The edges of both upper blank 1a and lower blank 1b may have rounded corners. Both upper blank 1a and lower blank 1b can have complex curved surfaces. The edges of upper blank 1a and lower blank 1b form the welding point, through which a gold product, such as gold jewelry, can be obtained.

[0036] Before placing the upper blank 1a and the lower blank 1b in the slot 1211 of the tray 121, one or more points can be pre-welded between the edges of the upper blank 1a and the lower blank 1b to achieve pre-positioning of the upper blank 1a and the lower blank 1b.

[0037] Gold products come in various shapes and / or sizes, such as round, heart-shaped, apple-shaped, cloud-shaped, and animal-shaped, with length and width ranging from 10 mm to 100 mm. By configuring trays 121 of different specifications, each tray 121 can have slots 1211 of different shapes and / or sizes, allowing gold products of specific shapes and sizes to be positioned in the corresponding slots 1211 of the tray 121.

[0038] The welding vision module 100 provided in this application embodiment has a rotating part 112 of a rotary table 110 that can rotate relative to a fixed base 111 around a first axis A1. A tray 121 of a carrier 120 is detachably connected to the rotating part 112. A baffle 122 is provided between the tray 121 and the rotary table 110, and the outer edge projection of the baffle 122 covers the outer edge projection of the tray 121. When processing a workpiece 1 of a predetermined shape and size, a tray 121 of the appropriate specification is selected, allowing the workpiece 1 to be placed in the slot 1211 of the tray 121, providing good compatibility. In scenarios involving the gripping edge of workpiece 1 such as gold products during welding, a ring light source 130 illuminates the carrier 120 and the workpiece 1, which is beneficial for the first camera 140 to capture realistic, shadow-free, and distortion-free images. The first camera 140 takes pictures of the workpiece 1, the tray 121 and the baffle 122. The baffle 122 can block the area below the baffle 122 (such as most of the area of ​​the rotary table 110), reducing unnecessary reflected light entering the first camera 140, so as to obtain a clear image of the workpiece 1 and realize the real and accurate grasping of the edge of the workpiece 1.

[0039] The area obstructed by the baffle 122 can be enlarged, and the area of ​​different trays 121 can be set with reference to the size of the corresponding workpiece 1. When the area of ​​the workpiece 1 is large, the area of ​​the tray 121 can be made large to arrange large slots 1211 on the tray 121 to place the large workpiece 1. When the area of ​​the workpiece 1 is small, the area of ​​the tray 121 can be made small to arrange small slots 1211 on the tray 121 to place the small workpiece 1. It is not necessary to make the area of ​​all trays 121 large, which can reduce costs.

[0040] In some embodiments, please refer to Figures 1 to 3 The rotary table 110 may include a control motor, which drives the carrier 120 to rotate around the first axis A1. The output shaft of the control motor is connected to the rotating part 112 of the rotary table 110 to drive the rotating part 112 to rotate around the first axis A1. The output shaft of the control motor and the rotating part 112 can be connected by a transmission structure (such as a transmission gear).

[0041] In some embodiments, please refer to Figures 1 to 3 The rotating part 112 has a positioning hole 1121 extending along the direction of the first axis A1, and the tray 121 has a positioning rod 1212, which is inserted into the positioning hole 1121 so that the positioning rod 1212 and the rotating part 112 are connected by profiles. The profile connection is a detachable connection in which a shaft with a non-circular cross section mates with a hub hole of the same profile to transmit motion and torque.

[0042] The positioning rod 1212 of the tray 121 and the positioning hole 1121 of the rotating part 112 have the same non-circular cross-section, such as D-shaped or rectangular, to achieve a detachable connection between the rotating part 112 and the tray 121. When the positioning rod 1212 is inserted into the positioning hole 1121, motion and torque can be transmitted between the rotating part 112 and the tray 121. To separate the tray 121 and the rotating part 112, the positioning rod 1212 is simply disengaged from the positioning hole 1121. Assembly and disassembly operations are very convenient.

[0043] In some embodiments, please refer to Figures 1 to 3 The rotating part 112 is fitted with a support sleeve 113. A ring-shaped baffle 122 is fitted over the rotating part 112 and supported on the support sleeve 113. A tray 121 rests against the baffle 122. This arrangement facilitates the placement of the baffle 122 between the tray 121 and the rotating table 110, with the tray 121 and baffle 122 stacked together. The ring light source 130 illuminates the carrier 120, creating a stable, uniform planar light effect without significant color difference. This allows the first camera 140 to clearly capture images of the workpiece 1 on the carrier 120, enabling accurate and realistic grasping of the workpiece 1's edges.

[0044] In some embodiments, please refer to Figures 1 to 3 The bottom end of the support sleeve 113 abuts against the rotating part 112, and the bottom of the inner edge of the annular baffle 122 abuts against the top end of the support sleeve 113. The positioning rod 1212 of the tray 121 is inserted into the positioning hole 1121 of the rotating part 112, and the bottom surface of the tray 121 abuts against the top surface of the baffle 122. This ensures that the baffle 122 is reliably positioned between the support sleeve 113 and the tray 121.

[0045] In some embodiments, please refer to Figures 1 to 3 The positioning rod 1212 is fixed to the rotating part 112 by the positioning pin 114. The positioning pin 114 passes through the support sleeve 113 and the rotating part 112 and abuts against the positioning rod 1212. This reliably fixes the tray 121 on the rotating part 112, and the rotating part 112 and the tray 121 rotate synchronously. The support sleeve 113 is limited on the rotating part 112, and the baffle 122 is sandwiched between the support sleeve 113 and the tray 121, so that the baffle 122 is reliably positioned on the rotating part 112, and the rotating part 112 and the baffle 122 rotate synchronously.

[0046] In some embodiments, please refer to Figures 1 to 3The angle θ between the normal 130c of the light-emitting surface 130a of the ring light source 130 and the central axis 130b of the ring light source 130 ranges from [45°, 75°]. The normal 130c of the light-emitting surface 130a of the ring light source 130 is perpendicular to the light-emitting surface 130a. The ring light source 130 outputs tilted ring light, which illuminates the carrier 120 and the workpiece 1, highlighting the edge of the workpiece 1 and reducing unnecessary reflected light entering the first camera 140, thus facilitating the first camera 140 to capture realistic, shadow-free, and distortion-free images.

[0047] For example, the angle θ between the normal 130c of the light-emitting surface 130a of the ring light source 130 and the central axis 130b of the ring light source 130 can be 45°, 60°, 75°, etc., and can be set as needed.

[0048] In some embodiments, please refer to Figures 1 to 3 A polarizing filter (not shown) is provided on the light-incident side of the first camera 140. The polarizing filter can effectively filter out light from a specific direction and reduce reflected light entering the first camera 140, which is beneficial for the first camera 140 to capture realistic, shadow-free, and distortion-free images.

[0049] In some embodiments, please refer to Figures 1 to 3 The tray 121 has a vacuum adsorption channel (not shown in the figure), which is connected to the slot 1211. The vacuum adsorption channel is connected to a negative pressure source, which uses negative pressure to vacuum adsorb the workpiece 1 onto the tray 121, and the workpiece 1 can be kept on the tray 121 during movement.

[0050] In some embodiments, please refer to Figures 1 to 3 Both tray 121 and baffle 122 are white. When the ring light source 130 illuminates the carrier 120 and the workpiece 1, a stable, uniform planar light effect with no obvious color difference can be formed, which is beneficial for the first camera 140 to clearly photograph the workpiece 1 on the carrier 120 and realize the true and accurate grasping of the edge of the workpiece 1.

[0051] In some embodiments, please refer to Figures 1 to 3 The tray 121 can be circular, and the baffle 122 can be annular. The tray 121 and the baffle 122 are easy to form. When the turntable 110 rotates the vehicle 120 to any position, the shape of the vehicle 120 captured by the first camera 140 is close to or the same.

[0052] In some embodiments, please refer to Figures 1 to 3 The output light of the ring light source 130 is red light. When the ring light source 130 outputs red light towards the carrier 120 and the workpiece 1, a stable planar uniform light effect with no obvious color difference can be formed, which is beneficial for the first camera 140 to clearly photograph the workpiece 1 on the carrier 120 and realize the true and accurate grasp of the edge of the workpiece 1.

[0053] In some embodiments, please refer to Figures 1 to 3 The first camera 140 can be a charge-coupled device (CCD) camera, which can achieve clear imaging of the carrier 120 and the workpiece 1.

[0054] Please see Figures 4 to 7 This application provides a gold welding machine 1000, including: a first linear module 200, a second linear module 300, a third linear module 400, a laser head module 500, and the aforementioned welding vision module 100. A fixed base 111 of a rotary table 110 is connected to the first linear module 200, which drives the rotary table 110 to translate along a first direction X. The third linear module 400 is connected to the second linear module 300, which drives the third linear module 400 to translate along a second direction Y. A ring light source 130, a first camera 140, and the laser head module 500 are all connected to the third linear module 400, which drives the ring light source 130, the first camera 140, and the laser head module 500 to move along a third direction Z. The first direction X, the second direction Y, and the third direction Z are mutually perpendicular, and the third direction Z is parallel to the direction of the first axis A1.

[0055] The gold welding machine 1000 provided in this application embodiment has a first linear module 200 that can drive a rotary table 110 to translate along a first direction X, a second linear module 300 that can drive a third linear module 400 to translate along a second direction Y, and a third linear module 400 that can drive a ring light source 130, a first camera 140, and a laser head module 500 to translate along a third direction Z. This enables the ring light source 130 and the first camera 140 to be coaxially aligned with the rotary table 110, and the laser output L of the laser head module 500 to be directed towards the workpiece 1 on the carrier 120. The ring light source 130 illuminates the carrier 120 and the workpiece 1, the first camera 140 captures an image of the workpiece 1 on the carrier 120, and the laser output L of the laser head module 500 irradiates the welding position of the workpiece 1, achieving automatic welding and seamless full welding of the workpiece 1 with high welding efficiency. The operation is simple, convenient, safe, and reliable.

[0056] In some embodiments, please refer to Figures 4 to 7The first linear module 200, the second linear module 300, and the third linear module 400 can output linear motion. By adjusting the orientation of the linear modules, linear displacement output in different directions can be achieved. The linear modules can be synchronous belt type, ball screw type, or linear motor type, which are conventional technologies. The first linear module 200 can drive the rotary table 110 to translate along the first direction X. The second linear module 300 and the third linear module 400, combined, can drive the ring light source 130, the first camera 140, and the laser head module 500 to move within the plane formed by the second direction Y and the third direction Z.

[0057] The first linear module 200 can be mounted on the workbench 610, and the second linear module 300 can be mounted on the gantry 620, which is mounted on the workbench 610.

[0058] In some embodiments, please refer to Figures 4 to 7 The laser head module 500 outputs a laser L, which is projected onto the surface of the workpiece 1 to generate heat, thus completing laser welding. The laser head module 500 may be equipped with a second camera 510, which is used to capture the welding position of the workpiece 1 along a first direction X. The laser head module 500 is coupled to a laser generator (not shown), which generates the laser, and the laser head module 500 outputs the laser generated by the laser generator. The laser generator is located outside the worktable 610.

[0059] In some embodiments, please refer to Figures 4 to 7 The controller (not shown) is communicatively connected to the first camera 140, the laser head module 500, the rotary table 110, the first linear module 200, the second linear module 300, and the third linear module 400. The controller can convert the images captured by the first camera 140 into drive signals, which are used to drive the rotary table 110, the first linear module 200, the second linear module 300, and the third linear module 400 to move.

[0060] Combination Figure 1 The rotary table 110 drives the carrier 120 and the workpiece 1 to rotate around the first axis A1. The first linear module 200, the second linear module 300 and the third linear module 400 move in coordination to guide the laser L output by the laser head module 500 to irradiate different welding positions of the workpiece 1 (i.e., the edges of the upper blank 1a and the lower blank 1b). This ensures that the focal length of the laser emission remains basically unchanged when the laser L irradiates different welding positions of the workpiece 1, so that the heat dissipation ratio and heat absorption ratio of the workpiece 1 are basically balanced, the laser output power is basically consistent, and the welding effect of different positions of the workpiece 1 is similar.

[0061] In some embodiments, please refer to Figures 4 to 8The system also includes a cabinet 600, within which a first linear module 200, a second linear module 300, a third linear module 400, and a laser head module 500 are housed. The first linear module 200 has a movable end 210 that can translate along a first direction X. The cabinet 600 has an opening 601 through which the movable end 210 passes. The movable end 210 has a processing position 210a and a loading / unloading position 210b, with the processing position 210a located inside the cabinet 600 and the loading / unloading position 210b located outside the cabinet 600.

[0062] Different linear modules and laser head modules 500 are housed within a cabinet 600, confining the welding process within the cabinet 600 and ensuring welding safety. The first linear module 200 transports the rotary table 110, carrier 120, and workpiece 1 between processing position 210a and loading / unloading position 210b. When the moving end 210 of the first linear module 200 moves to processing position 210a, placing the rotary table 110, carrier 120, and workpiece 1 within the cabinet 600, the laser head module 500 outputs laser light to weld the workpiece 1. When the moving end 210 of the first linear module 200 moves to loading / unloading position 210b, placing the rotary table 110, carrier 120, and workpiece 1 outside the cabinet 600, facilitating the removal of the welded workpiece 1 from the carrier 120 and the loading of the unwelded workpiece 1 into the carrier 120.

[0063] The opening 601 of the cabinet 600 can be equipped with a movable door (not shown in the figure). The movable door can be closed during welding processing and opened when the first linear module 200 is transmitting data.

[0064] In some embodiments, please refer to Figures 4 to 7 The number of the first linear module 200, the rotary table 110 and the vehicle 120 are all two. The two first linear modules 200 are arranged at intervals along the second direction Y. The rotary table 110 and the vehicle 120 are set in a one-to-one correspondence. The rotary table 110 and the first linear module 200 are set in a one-to-one correspondence.

[0065] By arranging two sets of first linear modules 200, a rotary table 110, and a carrier 120, welding and loading / unloading efficiency can be improved, thereby increasing production efficiency. During production, the moving end 210 of one set of first linear modules 200 is moved to processing position 210a, placing the corresponding rotary table 110, carrier 120, and workpiece 1 inside the cabinet 600. The laser head module 500 outputs laser light to weld the workpiece 1. The moving end 210 of the other set of first linear modules 200 is moved to loading / unloading position 210b, placing the corresponding rotary table 110, carrier 120, and workpiece 1 outside the cabinet 600. This facilitates the removal of the welded workpiece 1 from the carrier 120 and the loading of the unwelded workpiece 1 into the carrier 120.

[0066] In some embodiments, please refer to Figure 4 , Figure 8 It also includes a screen 700, which can display information such as the images captured by the first camera 140 and the second camera 510. The screen 700 may also have touch functionality to detect touch operations applied to or near it. The screen 700 may be mounted on a cabinet 600.

[0067] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
