Description

Technical Field

[0001] The present invention relates to the technical field of automatic welding, and in particular to a welding device and a welding method. Background Art

[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 lines between the multiple solder joints is different from the first direction, the second direction and the third direction. Therefore, when welding at multiple welding stations, automatic welding equipment capable of multi-directional movement is generally used for welding, or the welding head is prepared into a contoured structure to cover multiple welding stations.

The moving component includes a first linear module, a second linear module and a third linear module to drive the welding head to move in a first direction, a second direction and a third direction perpendicular to each other to weld welds at any position. In the process of cooperation of multiple linear modules, the motion error generated expands after accumulation, which easily leads to position deviation when moving to the subsequent weld position, thereby resulting in unqualified welding and reduced qualified rate. At the same time, the customized contoured welding head has high quality requirements, high cost, and is prone to failure, resulting in reduced welding efficiency.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0070] Embodiments of the present invention are described in detail below, examples of which 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 only used to explain the present invention, and cannot be understood as limiting the present invention.

[0071] 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.

[0072] The welding device comprises a frame 100, a first moving member 210, a bearing platform 300, a locking member 400, a second moving member 220, a third moving member 230 and a welding head 240. The first moving member 210 is arranged on the frame 100 and can reciprocate along a first direction; the bearing platform 300 is rotationally matched with the first moving member 210 and can rotate relative to the first moving member 210 around a rotation axis; the bearing platform 300 is used to place a product 1000 and can drive the product 1000 to rotate synchronously; the locking member 400 is arranged on the first moving member 210 and can move relative to the first moving member 210 along the direction of the rotation axis to apply pressure to the bearing platform 300 and lock the bearing platform 300 with the first moving member 210; the second moving member 220 0 is arranged on the frame 100 and can reciprocate along the second direction; the third moving member 230 is arranged on the second moving member 220 and can reciprocate 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 bearing platform 300 drives the product 1000 to rotate synchronously, so that the connection line between at least two welding positions on the product 1000 is parallel to the second direction, in other words, after the bearing platform 300 drives the product 1000 to rotate synchronously, the connection 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. The first moving member 210, the second moving member 220, and the third moving member 230 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.

[0073] With the help of the structure of the above-mentioned support platform 300 rotating on the first movable part 210, after the support platform 300 is rotated and adjusted relative to the first movable part 210, the connection line between at least two welding positions on the product 1000 placed on the support platform 300 can be parallel to the second direction, so that during the welding process, the first movable part 210 can be avoided from participating in the coordinated action. Through the single action of the second movable part 220, the welding head 240 can be moved 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, which is convenient for controlling the welding head 240 to move to the subsequent welding position, thereby improving 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.

[0074] In some embodiments, the welding device further includes a rotating member 500, the rotating member 500 includes a fixed portion and a rotating portion, the rotating member 500 is fixedly connected to the first moving member 210 via the fixed portion, the carrier 300 has a matching portion that matches the rotating portion, and the carrier 300 rotates and matches with the rotating portion via the matching portion. With the arrangement of the rotating member 500, the structure of the first moving member 210 and the carrier 300 can be simplified, and the rotating member 500 is a wearing part, and the manner of setting it separately is convenient for replacement during subsequent maintenance, thereby reducing maintenance costs.

[0075] Combination Figure 5 and Figure 6 As shown, to facilitate the assembly of the carrier 300, in some embodiments, the rotating member 500 includes a first truncated table 510 and a second truncated table 520 which are coaxially arranged and sequentially connected along the third direction, the diameter of the first truncated table 510 is larger than the diameter of the second truncated table 520, the first truncated table 510 forms a fixed portion and is connected to the first moving member 210, the carrier 300 has a rotating channel 311, and the second truncated table 520 forms a rotating portion and is inserted into the rotating channel 311. During assembly, the carrier 300 is placed on the first moving member 210, and the second truncated table 520 can be easily inserted into the rotating channel 311 by visual inspection; at the same time, compared with the first moving member 210, it is easier to process the second truncated table 520 on the first truncated table 510 with a smaller size. In addition, the first truncated table 510 and the second truncated table 520 can also be integrally formed.

[0076] 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 arrangement enables the second truncated table 520 to contact the side wall of the upper channel of the first movable member 210, thereby preventing the fastening screws from being subjected to radial shear force, thereby improving stability and service life; at the same time, it prevents the step surface between the first truncated table 510 and the second truncated table 520 from supporting the supporting platform 300. The supporting platform 300 is supported by the first movable member 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, thereby avoiding tilting due to suspension.

[0077] 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.

[0078] In order to realize the locking of the bearing platform 300 and the first moving part 210, the bearing platform 300 is provided with an arc groove 312, and the arc groove 312 is arranged around the rotation axis. The first moving part 210 is provided with an adjusting screw hole 211, and the adjusting screw is arranged in the arc groove 312 and screwed in the adjusting screw hole 211. The nut of the adjusting screw can press the bearing platform 300 so that static friction is generated between the bearing platform 300 and the first moving part 210 to realize the locking, and the nut of the adjusting screw can be away from the bearing platform 300 so that the bearing platform 300 can rotate relative to the first moving part 210. This kind of setting can not only provide guidance for the rotation of the bearing platform 300, but also can realize the adjustment of the bearing platform 300 at 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, so as to improve the adjustment efficiency. Among them, for the products 1000 of the same batch and model, it is only necessary to adjust the angle of the bearing 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.

[0079] 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 .

The product 1000 is carried by the carrier 600 and placed on the carrier 300 simultaneously, and after welding is completed, the carrier 600 is moved out of the carrier 300 together with the product 1000. Under the protection of the carrier 600, the safety of the product 1000 during the transfer process is improved. For different models of products 1000, the carrier 600 can be replaced to correspond to them.

[0081] 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 disposed on the supporting body 310, the first limiting member 320 and the two second limiting members 330 forming 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, and 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, and the two width side walls of the carrier 600 correspond to the two second limiters 330. The carrier 600 is placed between the two second limiters 330 at the opening, and then the carrier 600 is pushed in the direction of the first limiter 320, and finally the length side wall of the carrier 600 abuts against the first limiter 320 to complete the placement of the carrier 600. The entire placement process is efficient and fast, which helps to improve welding efficiency. Among them, the carrier 600 also includes a transfer handle 690, which is provided on the carrier body 310 for easy handholding.

[0082] In order to improve the relative position accuracy between the carrier 600 and the carrier platform 300, in some embodiments, the second stopper 330 is installed with a ball plunger 340, and the ball head of the ball plunger 340 is used to abut against one width side wall of the carrier 600, so that the other width side wall of the carrier 600 abuts against another second stopper 330.

[0085] Specifically, combined Figure 6 and Fig. 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 forms 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, the toggle member 640 drives the second transmission member 672 away from the first positioning member 611 through the toggle portion 642 during the rotation process, 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 of 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 the structure is simple, and the operation process is stable and reliable. Among them, the second transmission member 672 is a prismatic structure to avoid rotation during the sliding process. A driving groove is formed on a side of the second transmission member 672 facing the second clamping member 650 , and one side wall of the driving groove forms a first inclined surface 6721 .

[0086] In order to facilitate the automatic reset of the second transmission member 672, a reset elastic member 6722 is also arranged 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, thereby ensuring that the second transmission member 672 is always in contact with the toggle part 642.

[0087] Combination Fig. 9 and Fig.10As shown, the toggle member 640 is in the shape of a rod, and a rotating part 641 of a cylindrical structure is formed at both ends, and a toggle part 642 of an eccentric cylindrical structure is formed in the middle. The toggle part 642 includes an arc surface 6421 and a contact plane 6422 arranged in an annular manner. During the rotation of the toggle member 640, the arc surface 6421 can contact the input end of the transmission component and drive the first clamping member 620 away from the first positioning member 611, or the contact plane 6422 can contact the input end of the transmission component, and under the action of the first elastic member 630, the first clamping member 620 approaches the first positioning member 611. The arc surface 6421 and the contact plane 6422 are transitioned by a circular arc surface. Specifically, the toggle portion 642 abuts against one end of the first transmission member 671 away from the first clamping member 620, and abuts against one end of the second transmission member 672 away from the first clamping member 620, and the first transmission member 671 and the second transmission member 672 are arranged at intervals 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, and the rod-shaped toggle member 640 is small in size, low in cost, and occupies little space.

[0088] 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.

[0089] Combination Figures 6 to 8 As shown, in some embodiments, the product 1000 includes a first part 1100 and a second part 1200, and the welding part 1300 is connected between the first part 1100 and the second part 1200, and is welded at the welding position on the first part 1100. In order to avoid the phenomenon that the welding part 1300 is lifted during the welding process, in some embodiments, the carrier 600 also includes a crimping assembly, which includes a crimping base 691 and a crimping member 692, wherein the crimping base 691 is detachably connected to the carrier tray 610 and is located above the product 1000; the crimping member 692 is rotatably disposed on the crimping base 691, and the crimping member 692 can be rotated to its own crimping end to crimp the welding part 1300 at the welding position of the product 1000, or can be rotated to its own crimping end away from the welding part 1300. Among them, the crimping shaft 693 is rotatably disposed on the crimping base 691, and the crimping member 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.

[0090] In order to prevent the heat generated during the welding process from radiating outwards 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 plate and is used to block the temperature at the welding position from radiating outwards. Among them, the crimping piece 692 includes a connecting plate 6921 and a crimping head 6922 set 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, and at least the crimping head 6922 is a flat structure. When in use, the crimping head 6922 is perpendicular to the extension direction of the long strip welding piece 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 the strength and can be adsorbed by the magnetic part to drive the crimping part 692 to rotate, thereby improving the efficiency of the crimping part 692 in crimping the welding part 1300. For example, a sheet metal part is embedded inside the crimping part 692 to form a metal interlayer, wherein the metal part is only arranged at the connecting plate 6921, and the connecting plate 6921 is a flat plate structure.

[0091] 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.

[0092] 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 is provided with a first groove, the crimping base 691 is provided with a second groove, the first groove and the second groove 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, and prevent the position of the crimping member 692 relative to the crimping base 691 from changing during the transfer process of the carrier 600 or the welding process, thereby causing the welding member 1300 to shift and cause welding failure.

[0093] Recombination Figure 2As shown, in some embodiments, the welding device has two first movable members 210, two supporting platforms 300 and two locking members 400, wherein the two supporting platforms 300 are spaced apart along the second direction, and are respectively rotatably matched with the corresponding two first movable members 210, and can be locked to the two first movable members 210 or unlocked with the two first movable members 210 through the corresponding two locking members 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.

[0094] To ensure welding efficiency, the welding device also has a heat sink, which cools the welded product 1000. The heat sink includes a universal bamboo tube 710, which is arranged on the third moving part 230, with the outlet facing the welding position and the inlet connected to the external blower mechanism.

[0095] Smoke and dust will be generated during the welding process. To clean the smoke and dust, the welding device further includes a suction pipe 720 provided with a third moving 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 for sucking smoke and / or polluted gas generated during the welding process to ensure the cleanliness and safety of the welding environment. In addition, the welding device further includes a housing 110, which has a receiving cavity. The welding process is completed in the receiving cavity to reduce smoke from escaping.

[0096] 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.

[0097] The present embodiment also provides a welding method, which is applied to the welding device in any of the above embodiments, and includes 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, and 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 member 210 can be avoided from participating in the coordinated action during the welding process. The second movable member 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 member 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.
