[0002] In an electronic product, welding needs to be performed at multiple welding stations to form multiple solder joints. The extension direction of the connection line between the multiple solder joints is different from the first direction, the second direction and the third direction.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0066] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0067] like Figures 1 to 10 As shown, this embodiment provides a welding device, wherein a welding pad 1110 is provided at each welding position of the product 1000, and the welding device is used to weld a plurality of welding parts 1300 to the plurality of welding pads 1110 respectively, and has high welding efficiency and high qualified rate.

[0068] The welding device includes a frame 100, a first moving part 210, a carrying platform 300, a locking member 400, a second moving part 220, a third moving part 230 and a welding head 240. Among them, the first moving part 210 is arranged on the frame 100 and can move back and forth along a first direction; the carrying platform 300 is rotatably matched with the first moving part 210 and can rotate relative to the first moving part 210 around a rotation axis. The carrying platform 300 is used to place the product 1000 and can drive the product 1000 to rotate synchronously; the locking member 400 is arranged on the first moving part 210 and can move relative to the first moving part 210 along the direction of the rotation axis to apply pressure to the carrying platform 300 and lock the carrying platform 300 with the first moving part 210; the second moving part 220 0 is arranged on the frame 100 and can move back and forth along the second direction; the third moving member 230 is arranged on the second moving member 220 and can move back and forth along the third direction, and the extension direction of the rotation axis is parallel to the third direction; the welding head 240 is arranged on the third moving member 230; after the supporting platform 300 drives the product 1000 to rotate synchronously, so that the line between at least two welding positions on the product 1000 is parallel to the second direction. In other words, after the supporting platform 300 drives the product 1000 to rotate synchronously, the line between the two welding pads 1110 is parallel to the second direction. Among them, the first direction is the front-to-back direction, the second direction is the left-to-right direction, and the third direction is the up-down direction. Regarding the first moving member 210, the second moving member 220, and the third moving member 230, they can all be linear modules, and the three output ends of the three linear modules can move along the first direction, the second direction, and the third direction respectively, that is, the three linear modules complete the relative three-dimensional movement between the product 1000 and the welding head 240.

[0069] With the help of the structure of the above-mentioned supporting platform 300 rotating on the first movable part 210, after the supporting platform 300 is rotated and adjusted relative to the first movable part 210, the connecting line between at least two welding positions on the product 1000 placed on the supporting platform 300 can be parallel to the second direction, so that the first movable part 210 can be avoided from participating in the coordinated action during the welding process. The welding head 240 can be moved to the two welding positions for welding by the second movable part 220 moving alone. The unidirectional movement of the second movable part 220 reduces the motion error generated by the welding head 240, facilitates the control of the welding head 240 to move to the subsequent welding position, and improves the welding accuracy and qualified rate; at the same time, a conventional welding head 240 can be used in the welding process, and there is no need to design it as a contoured structure. The structure is simple, durable, low cost, and not prone to failure, which helps to ensure welding efficiency.

[0070] In some embodiments, the welding device further includes a rotating member 500, which includes a fixed portion and a rotating portion. The rotating member 500 is fixedly connected to the first movable member 210 via the fixed portion. The supporting platform 300 includes a mating portion that mates with the rotating portion, and the supporting platform 300 rotatably engages with the rotating portion via the mating portion. The provision of the rotating member 500 simplifies the structure of the first movable member 210 and the supporting platform 300. The separate provision of the rotating member 500 as a consumable part facilitates replacement during subsequent maintenance, thereby reducing maintenance costs.

[0071] Combine Figure 5 and Figure 6 As shown, in order to facilitate the assembly of the carrier 300, in some embodiments, the rotating member 500 includes a first truncated cone 510 and a second truncated cone 520 that are coaxially arranged and connected in sequence along the third direction. The diameter of the first truncated cone 510 is larger than the diameter of the second truncated cone 520. The first truncated cone 510 forms a fixed portion and is connected to the first movable member 210. The carrier 300 has a rotating channel 311, and the second truncated cone 520 forms a rotating portion and is inserted into the rotating channel 311. During assembly, the carrier 300 is placed on the first movable member 210, and the second truncated cone 520 can be easily inserted into the rotating channel 311 by visual inspection. At the same time, compared with the first movable member 210, it is easier to process the second truncated cone 520 on the first truncated cone 510 with a smaller size. In addition, the first truncated cone 510 and the second truncated cone 520 can also be formed in one piece.

[0072] The first movable member 210 is provided with an upper channel and a lower channel connected along a third direction, wherein the diameter of the lower channel is larger than the diameter of the upper channel, the first frustum 510 is located in the lower channel, and the end face of the first frustum 510 facing the second frustum 520 is abutted against the step surface between the lower channel and the upper channel; the second frustum 520 is partially located in the upper channel and partially located inside the rotating channel 311; the first frustum 510 has a mounting hole, and the first movable member 210 is provided with a threaded hole at the step surface, and the fastening screw passes through the mounting hole and is screwed into the threaded hole. The above-mentioned setting makes the second truncated table 520 contact the side wall of the upper channel of the first movable part 210, avoiding the fastening screws from being subjected to radial shear force, thereby improving stability and service life; at the same time, it avoids the step surface between the first truncated table 510 and the second truncated table 520 from supporting the supporting platform 300, and the supporting platform 300 is supported by the first movable part 210, with a larger supporting area and a better supporting effect, so that all parts of the supporting platform 300 except the rotating channel 311 can be effectively supported, avoiding tilting caused by suspension.

[0073] In other embodiments, the rotating portion may be a rotating groove, and a rotating protrusion is provided at the bottom of the supporting platform 300 , and the rotating protrusion can be located in the rotating groove.

[0074] In order to realize the locking connection between the carrier platform 300 and the first movable member 210, the carrier platform 300 is provided with an arcuate groove 312, which is arranged around the rotation axis. The first movable member 210 is provided with an adjusting screw hole 211. The adjusting screw is arranged in the arcuate groove 312 and is screwed into the adjusting screw hole 211. The nut of the adjusting screw can press the carrier platform 300 so that static friction is generated between the carrier platform 300 and the first movable member 210 to realize the locking connection, and the nut of the adjusting screw can be away from the carrier platform 300 so that the carrier platform 300 can rotate relative to the first movable member 210. This arrangement can not only provide a guide for the rotation of the carrier platform 300, but also can realize the adjustment of the carrier platform 300 to any angle within a certain range to meet different welding positions; finally, when adjusting, only slightly loosen the adjusting screw, and tighten the adjusting screw after the adjustment is completed, thereby improving the adjustment efficiency. Among them, for products 1000 of the same batch and model, it is only necessary to adjust the angle of the carrier platform 300 once. For different models of products 1000, when the connection directions of different welding positions change, it is only necessary to adjust the supporting platform 300, thereby avoiding replacement and reducing costs.

[0075] To prevent the adjusting screw from affecting the product 1000 , in some embodiments, the arc-shaped groove 312 is a countersunk groove, and the top of the adjusting screw is located below the top surface of the first moving member 210 .

[0076] In some embodiments, the welding apparatus further includes a carrier 600, which is detachably connected to the carrier platform 300 and is used to carry the product 1000. The carrier 600 carries the product 1000 and simultaneously places it on the carrier platform 300. After welding is complete, the carrier 600 and the product 1000 are removed from the carrier platform 300. The protective effect of the carrier 600 improves the safety of the product 1000 during transfer. The carrier 600 can be replaced to accommodate different models of product 1000.

[0077] In order to improve the efficiency of placing the carrier 600 on the supporting platform 300, in some embodiments, the supporting platform 300 includes a supporting body 310 and a first limiting member 320 and two second limiting members 330 provided on the supporting body 310. The first limiting member 320 and the two second limiting members 330 form a limiting groove with an opening away from the first limiting member 320. The carrier 600 is placed in the limiting groove. The first limiting member 320 is used to limit the length side wall of the carrier 600. The second limiting members 330 are arranged at intervals along the width direction of the carrier 600 and are respectively used to limit the two width side walls of the carrier 600. With the above arrangement, the carrier 600 can be placed on the carrier body 310, with the two width sidewalls of the carrier 600 aligned with the two second stoppers 330. The carrier 600 is then placed between the two second stoppers 330 at the opening, and then pushed toward the first stoppers 320, ultimately bringing the length sidewalls of the carrier 600 into contact with the first stoppers 320 to complete the placement of the carrier 600. The entire placement process is efficient and quick, helping to improve welding efficiency. The carrier 600 also includes a transfer handle 690, which is provided on the carrier body 310 for easy handholding.

[0078] To improve the relative positioning accuracy between the carrier 600 and the supporting platform 300, in some embodiments, the second stopper 330 is equipped with a ball plunger 340. The ball head of the ball plunger 340 is used to abut one width side wall of the carrier 600, thereby causing the other width side wall of the carrier 600 to abut against the other second stopper 330. The length direction H of the carrier 600 is the same as the length direction of the product 1000, and the width direction W of the carrier 600 is the same as the width direction of the product 1000.

[0079] To enable the product 1000 to be quickly installed on or removed from the carrier 600 , in some embodiments, the carrier 600 includes a carrying tray 610 , a first clamping member 620 , a first elastic member 630 , a transmission assembly, and a toggle member 640 .

During use, the toggle member 640 is operated to move the first clamping member 620 away from the first positioning member 611 , so that the product 1000 can be taken out; when placing the product 1000 , the toggle member 640 is operated in the reverse direction.

[0080] In order to improve the relative position accuracy of the product 1000 and the carrier 600, in some embodiments, the carrier 600 also includes a second clamping member 650 and a second elastic member 660, wherein the carrying tray 610 is provided with a second positioning member 612; the second clamping member 650 is slidably arranged on the carrying tray 610 along the width direction of the carrier 600, and can approach or move away from the second positioning member 612; the second elastic member 660 is arranged between the carrying tray 610 and the second clamping member 650, and is used to apply an elastic force to the second clamping member 650 to make it close to the second positioning member 612; the second output end of the transmission assembly is connected to the second clamping member 650, and the rotation process of the toggle member 640 can synchronously drive the second output end of the transmission assembly to move, so as to drive the second clamping member 650 away from the second positioning member 612. The above-mentioned arrangement enables the first clamping member 620 and the second clamping member 650 to position the product 1000 in two directions respectively, thereby ensuring the relative position accuracy between the product 1000 and the carrier 600; in addition, under the action of the transmission assembly, when the toggle member 640 is operated, the first clamping member 620 and the second clamping member 650 can move synchronously, thereby improving the efficiency of taking and placing the product 1000, thereby helping to improve the welding efficiency.

[0081] Specifically, combined Figure 6 and Figure 9As shown, the transmission assembly includes a first transmission member 671 and a second transmission member 672. The first transmission member 671 is slidably disposed on the carrying tray 610 along the length direction of the carrier 600 and abuts against the first clamping member 620. During the rotation process of the toggle member 640, the toggle portion 642 drives the first transmission member 671 away from the first positioning member 611. The first transmission member 671 can drive the first clamping member 620 away from the first positioning member 611; the second transmission member 672 is slidably disposed on the carrying tray along the length direction of the carrier 600. 610, and has a first inclined surface 6721, the first inclined surface 6721 forming a second output end, the first inclined surface 6721 is inclined from the direction close to the first clamping member 620 to the direction away from the second clamping member 650, the second clamping member 650 is provided with a second inclined surface parallel to the first inclined surface 6721, and during the rotation of the toggle member 640, the second transmission member 672 is driven away from the first positioning member 611 through the toggle portion 642, and the second transmission member 672 can drive the second clamping member 650 away from the second positioning member 612. During the movement of the second transmission member 672, the cooperation between the first inclined surface 6721 and the second inclined surface can push the second clamping member 650 away from the second positioning member 612. This arrangement enables the toggle member 640 to synchronously drive the first clamping member 620 and the second clamping member 650 during the rotation process, and has a simple structure and a stable and reliable operation process. Among them, the second transmission member 672 is a prismatic structure to prevent rotation during the sliding process. A driving groove is defined on a side of the second transmission member 672 facing the second clamping member 650 , and a first inclined surface 6721 is formed on one sidewall of the driving groove.

[0082] In order to facilitate the automatic reset of the second transmission member 672, a reset elastic member 6722 is also provided between the second transmission member 672 and the carrying tray 610. The reset elastic member 6722 is used to apply elastic force to the second transmission member 672 so that the second transmission member 672 moves in a direction close to the toggle member 640, so that the second transmission member 672 is always in contact with the toggle part 642.

[0083] Combine Figure 9 and Figure 10As shown, the toggle member 640 is rod-shaped, with cylindrical rotating portions 641 formed at both ends and an eccentric cylindrical toggle member 642 formed in the middle. The toggle member 642 includes an annularly arranged arcuate surface 6421 and an abutting plane 6422. During the rotation of the toggle member 640, the arcuate surface 6421 can abut the input end of the transmission assembly, driving the first clamping member 620 away from the first positioning member 611, or the abutting plane 6422 can abut the input end of the transmission assembly, and under the action of the first elastic member 630, the first clamping member 620 approaches the first positioning member 611. The arcuate surface 6421 and the abutting plane 6422 are transitioned by a circular arc surface. Specifically, the toggle portion 642 abuts against an end of the first transmission member 671 away from the first clamping member 620, and abuts against an end of the second transmission member 672 away from the first clamping member 620. The first transmission member 671 and the second transmission member 672 are spaced apart along the width direction of the carrier 600. This arrangement facilitates the toggle member 640 to synchronously drive the first transmission member 671 and the second transmission member 672. The rod-shaped toggle member 640 is compact, low-cost, and occupies little space.

[0084] To facilitate the operation of the toggle member 640, a gripping member 680 is provided at one end of the toggle member 640. The gripping member 680 extends in a direction perpendicular to the axis of the toggle member 640. The gripping member 680 and the toggle member 640 form an L shape to increase the force arm when the toggle member 640 rotates, thereby improving the convenience of operation.

[0085] Combine Figures 6 to 8 As shown, in some embodiments, product 1000 includes a first part 1100 and a second part 1200, and a welding piece 1300 is connected between the first part 1100 and the second part 1200 and welded to the welding position on the first part 1100. To prevent the welding piece 1300 from warping during the welding process, in some embodiments, the carrier 600 further includes a crimping assembly, which includes a crimping base 691 and a crimping piece 692. The crimping base 691 is detachably connected to the carrier tray 610 and is located above the product 1000. The crimping piece 692 is rotatably mounted on the crimping base 691. The crimping piece 692 can rotate to its own crimping end to crimp the welding piece 1300 at the welding position of the product 1000, or can rotate to its own crimping end away from the welding piece 1300. The crimping shaft 693 is rotatably mounted on the crimping base 691, and the crimping piece 692 is fixedly connected to the crimping shaft 693. This arrangement allows the welding part 1300 to be pressed by the crimping part 692 after the product 1000 is placed on the carrier 600 and to abut against the first part 1100 at the welding position, thereby avoiding warping during the welding process and improving the welding effect.

[0086] In order to prevent the heat generated during the welding process from radiating outward and causing the temperature of the second part 1200 to rise and cause damage, in some embodiments, the crimping end of the crimping piece 692 is in the shape of a flat plate and is used to prevent the temperature at the welding position from radiating outward. The crimping piece 692 includes a connecting plate 6921 and a crimping head 6922 arranged at an angle. One end of the connecting plate 6921 is fixedly connected to the crimping shaft 693, and the other end is integrally formed with the crimping head 6922. At least the crimping head 6922 is a flat plate structure. When in use, the crimping head 6922 is perpendicular to the extension direction of the long strip of welding part 1300 to separate the first part 1100 and the second part 1200. In some embodiments, the crimping piece 692 is made of a heat-insulating material. In some embodiments, the crimping piece 692 is made of a heat-insulating material and is provided with a metal interlayer inside to achieve heat insulation while improving its own strength. The metal interlayer can be made of stainless steel to improve strength while also being attracted by the magnetic element to drive the crimping member 692 to rotate, thereby improving the efficiency of the crimping member 692 in crimping the welded part 1300. For example, a sheet metal piece is embedded within the crimping member 692 to form the metal interlayer. The metal piece is only provided at the connecting plate 6921, which is a flat plate structure.

[0087] When two welding parts 1300 are required between the first part 1100 and the second part 1200, in order to prevent the two welding parts 1300 from being impacted and approaching each other during the welding process, which eventually causes the two welding parts 1300 to be welded together, thereby causing a short circuit, in some embodiments, the lower end of the crimping head 6922 has a crimping surface 6923 to crimp the welding parts 1300, and the crimping surface 6923 protrudes downward to form a partition 6924 to separate the two welding parts 1300, so that the two welding parts 1300 can be physically isolated, avoiding the two welding parts 1300 from approaching each other and being welded together during the welding process, thereby improving welding reliability.

[0088] In some embodiments, the crimping assembly further includes a cover plate 694, which is detachably connected to the crimping base 691. The cover plate 694 has a first groove, and the crimping base 691 has a second groove. The first and second grooves form a crimping channel 695, and the crimping member 692 is partially located in the crimping channel 695. This arrangement can fix the crimping member 692, preventing the position of the crimping member 692 relative to the crimping base 691 from changing during the transfer of the carrier 600 or the welding process, thereby causing the weldment 1300 to shift and causing welding failure.

[0089] Recombination Figure 2As shown, in some embodiments, the welding device has two first moving parts 210, two supporting platforms 300 and two locking parts 400, wherein the two supporting platforms 300 are spaced apart along the second direction and respectively rotated with the corresponding two first moving parts 210, and can be locked to the two first moving parts 210 or unlocked with the two first moving parts 210 through the corresponding two locking parts 400, so that the welding device can complete the replacement of the product 1000 on another supporting platform 300 when welding the product 1000 on one supporting platform 300, thereby improving the welding efficiency.

[0090] To ensure welding efficiency, the welding device also has a heat sink for cooling the welded product 1000. The heat sink includes a universal bamboo tube 710, which is provided on the third movable member 230, with its outlet facing the welding position and its inlet connected to an external blower mechanism.

[0091] The welding process produces smoke. To remove this smoke, the welding device also includes a suction pipe 720 equipped with a third movable member 230. The inlet of the suction pipe 720 faces the welding head 240, and the outlet of the suction pipe 720 is connected to an external suction mechanism. This is used to extract the smoke and / or pollutants generated during the welding process, thereby ensuring a clean and safe welding environment. The welding device also includes a housing 110 having a receiving chamber. The welding process is completed within the receiving chamber to reduce the escape of smoke.

[0092] To ensure welding accuracy, the welding device also has a camera 730, which is arranged on the third movable part 230 and can photograph the product 1000, specifically the position of the welding pad 1110 relative to the first part 1100, so that the welding head 240 can be accurately moved to the welding pad 1110 for welding.

[0093] This embodiment also provides a welding method, which is applied to the welding device in any of the above embodiments, including the following steps: adjusting the support platform 300 to rotate relative to the first movable member 210, and locking the support platform 300 and the first movable member 210 by the locking member 400; placing the product 1000 on the support platform 300, and the connecting line between at least two welding positions on the product 1000 extends along the second direction; the first movable member 210 is actuated to move the support platform 300 to the welding area of ​​the frame 100, and the second movable member 220 is actuated to drive the third movable member 230 and the welding head 240 on the third movable member 230 to move to one of the welding positions. After welding is completed, the welding head 240 is moved to another welding position for welding under the action of the second movable member 220. Before welding, the support platform 300 is rotated so that the connection line between at least two welding positions on the product 1000 can be parallel to the second direction, so that the first movable part 210 can be avoided from participating in the coordinated action during the welding process. The second movable part 220 can be moved alone to move the welding head 240 to the two welding positions for welding. The unidirectional movement of the second movable part 220 reduces the motion error generated by the welding head 240, facilitates the control of the welding head 240 to move to the subsequent welding position, and improves the welding accuracy and qualified rate. At the same time, a conventional welding head 240 can be used in the welding process, and there is no need to design it as a contoured structure. The structure is simple, durable, low-cost, and not prone to failure, which helps to ensure welding efficiency.
