Description

Technical Field

[0001] This utility model belongs to the technical field of laser welding equipment, and in particular relates to a laser electric welding device. Background Technology

[0002] Laser welding is a very common welding method, and laser welding machines have been widely used in the process of modernization. In industries such as consumer electronics, new energy batteries, and medical devices, the welding and assembly of small metal first pre-welded parts and second pre-welded parts supports is a core production process.

[0003] As the second pre-welded component becomes smaller and more integrated, higher requirements are placed on the feeding accuracy of the first pre-welded component, the consistency of double-sided welding, and production efficiency. For example, components such as mobile phone battery connectors and smartwatch sensor brackets require the first pre-welded component to be welded to the second pre-welded component on both sides. Under some high-requirement production standards, it is necessary to ensure that the welding position error of the first pre-welded component on the front and back sides of the second pre-welded component is controlled within ±0.05mm, while meeting the requirements of high-speed mass production.

[0004] In existing laser welding equipment, multiple production equipment are usually required to work together to complete processes such as feeding the first pre-welded part, welding the second pre-welded part and the first pre-welded part on both sides. Furthermore, since the equipment for flipping the second pre-welded part is generally quite complex, manual flipping is required when welding the first pre-welded part on the second pre-welded part on both sides. This not only results in low automation of double-sided laser welding, but also leads to problems such as low welding accuracy due to the collaborative work of multiple equipment.

[0071] Example 1:

[0072] like Figure 1 As shown, this embodiment proposes a laser welding equipment, including a transport device 1. The transport device 1 is sequentially equipped with a first feeding device 2, a second feeding device 3, a first welding device 4, a tilting device 5, and a second welding device 6 along a first direction X.

[0073] The transport device 1 is equipped with a carrier 11, which moves cyclically along a first direction X. The upper surface of the carrier 11 is provided with a first groove 111 and a second groove 112, and the bottom of the first groove 111 and the second groove 112 are both provided with a third groove 113. The first feeding device 2 is configured to feed the first pre-welded part onto the third groove 113, and the second feeding device 3 is configured to feed the second pre-welded part onto the first groove 111. The first welding device 4 is configured to weld the first welding surface of the second pre-welded part to the first pre-welded part. The flipping device 5 is configured to flip the second pre-welded part so that the first welding surface faces upward and place it on the second groove 112. The first welding device 4 is configured to weld the second welding surface of the second pre-welded part to the first pre-welded part.

[0074] Specifically, the transport device 1 is provided with a first feeding device 2, a second feeding device 3, a first welding device 4, a turning device 5, and a second welding device 6 along the first direction X, so that the carrier 11 moves cyclically in the above-mentioned device, so that the equipment can carry out large-scale welding production in a cyclic manner. The surface of the support component 11 is provided with a first groove 111 and a second groove 112, which are arranged in a mirror image adjacent to each other. Multiple third grooves 113 are provided in the first groove 111 and the second groove 112. During welding, the first pre-welded part is first placed in the third groove 113, and the first welding surface of the second pre-welded part is placed downward in the first groove 111 for welding. At this time, the first welding surface of the second pre-welded part abuts against the bottom of the first groove 111 and abuts against the first welded part in the first groove 111. At this time, the first welding surface of the second pre-welded part and the first pre-welded part are welded together, thereby achieving the effect of automated welding without the need for manual alignment welding. Moreover, the first groove 111, the second groove 112, and the third groove 113 set by the mold make the alignment more accurate and the error smaller than that of manual alignment. The carrier 11 can be a transport platform with a pre-formed first groove 111, second groove 112, and third groove 113. It can also be a UWV device to improve the accuracy of the placement device. It can also be a template with the pre-formed first groove 111, second groove 112, and third groove 113. The transport device 1 can be a linear motor, a ring conveyor belt composed of multiple conveyor belts, a chain belt, or the like.

[0075] The first feeding device 2 is configured to first feed the first pre-welded component into the third tank 113. After feeding, it cooperates with the second feeding device 3 to feed the second pre-welded component for welding. In actual operation, the second pre-welded component can be placed in either the first tank 111 or the second tank 112, which makes production more flexible. After the first welding device 4 finishes welding, the second pre-welded component is detached from the carrier 11 and flipped by the flipping device 5. Usually, the flip is 180°, but it can be any angle. The flipping device 5 can be a suction flip, a clamping flip, or a direct flip of the carrier 11. After flipping, by placing the first welding surface upward in the second tank 112, that is, by placing the second welding surface against the bottom of the second tank 112 and thus against the first welding component placed in the second tank 112, the second welding device 6 can weld the second welding surface of the second welding component to the first pre-welded component in the second tank 112. The above method can achieve fully automated double-sided welding, improving the overall level of automation. Furthermore, by performing step-by-step automatic flipping double-sided welding, the problem of deviation in secondary positioning can be avoided. This also avoids the problem of not being able to compensate for thermal deformation in real time during the welding process, which could lead to large deviations in the welding position of the first or second welding surface, resulting in defects such as incomplete welding and weld misalignment exceeding 10%.

[0076] By setting a transport device 1 in a laser welding equipment, the transport device 1 is sequentially equipped with a first feeding device 2, a second feeding device 3, a first welding device 4, a flipping device 5, and a second welding device 6 along a first direction X. The transport device 1 is equipped with a carrier 11, which moves cyclically along the first direction X. The first surface of the carrier 11 has a first groove 111 and a second groove 112 arranged adjacent to each other. A third groove 113 is arranged in both the first groove 111 and the second groove 112. The first feeding device 2 is configured to feed the first pre-welded part onto the third groove 113, and the second feeding device 3 is configured to feed the second pre-welded part onto the first groove 111. The first welding device 4 is configured to weld the first welding surface of the second pre-welded part to the first pre-welded part. The flipping device 5 is configured to flip the second pre-welded part so that the first welding surface faces upward and place it on the second groove 112. The first welding device 4 is configured to weld the second welding surface of the second pre-welded part to the first pre-welded part. This makes the equipment more coordinated, more precise, and more automated than the existing double-sided welding process for the first and second pre-welded parts.

[0077] Example 2:

[0078] Combination Figure 1 ,like Figures 2-13 As shown, this embodiment further explains and optimizes the structure proposed in Embodiment 1.

[0080] Specifically, the first groove 111 and the second groove 112 of the support member 11 are provided with multiple reference parts 114. The reference parts 114 can be reference platforms, and there can be one or more of them. They are set to assist in positioning and limiting the second pre-welded parts when they are placed, so that the second pre-welded parts can be placed quickly and accurately in the first groove 111 and the second groove 112 to ensure that the reference of the second pre-welded parts is consistent. It can be understood that the third groove 113 can also be provided with first pre-welded parts set to assist in positioning and limiting the first pre-welded parts, so as to assist in positioning the first pre-welded parts and ensure that the reference of all first pre-welded parts placed in the third groove 113 is consistent. Preferably, the edges of the first groove 111, the second groove 112, and the third groove 113 are all provided with guide parts 115. The guide parts 115 can be arc surfaces or inclined surfaces, so that the first and second pre-welded parts can be quickly placed in the area through the guide parts 115 when they are placed, and also avoid edge damage caused by mechanical stress between the second and first pre-welded parts and the edge of the area when they are placed.

The system comprises a hand 231, a first rotating seat 232, a first vision component (not shown in the figure), and a first suction head 233.

The first suction head 233 is located at the free end of the first robotic arm 231 to suction the first pre-welded component and transfer it to the carrier 11. The vision mechanism 22 is configured to determine whether the position of the first pre-welded component obtained by the first loading mechanism 23 meets the loading requirements. The first vision component can be a CCD, camera, etc., and is located on or directly above the first robotic arm 231 and the first suction head 233. It is configured to assist in positioning the first pre-welded component so that the first suction head 233 correctly suctions the first pre-welded component to the preset position.

[0082] Specifically, there can be multiple first feeding devices 2, such as 2, 3, 4, etc. The number is not limited and is determined according to the shape and placement of the first pre-welded part.

The first pre-welded component suction tray 212 is located at the bottom of the opening of the box. The first pre-welded component suction tray 212 can be a flexible vibrating tray, so that the tilted first pre-welded component naturally falls onto the first pre-welded component suction tray 212. At this time, the position of the first pre-welded component is random and not fixed. Therefore, the first pre-welded component adsorption plate 212 can be vibrated by the vibration structure at the bottom of the first pre-welded component adsorption plate 212, so that the first pre-welded component continuously changes its position to obtain the required position of the first pre-welded component. The first pre-welded component feeding structure can realize the feeding of the first pre-welded component without adjusting its position, thereby saving the complexity of production.

[0092] In some embodiments, the first welding apparatus 4 includes a first moving component 42 and a first laser welding component 41; the first moving component 42 drives the first laser welding component 41 to perform laser welding.

The first welding device 4 includes a first moving component 42, which may include a robotic arm mechanism. Its structure can be the same as the first loading mechanism 23 and will not be described in detail here. The first laser welding component 41 is positioned on the free end of the robotic arm and moves to perform welding. The first laser welding component 41 only welds the first tank 111 or the second tank 112, so that the first pre-welded part of the third tank 113 in the first tank 111 and the second pre-welded part of the first tank 111 are welded, or the first pre-welded part of the third tank 113 in the second tank 112 and the second pre-welded part of the second tank 112 are welded. The first laser welding component 41 is equipped with a vision module, such as a CCD or camera, which is used to assist the movement and welding of the laser welding head. The first welding device 4 welds only the first tank 111 or the second tank 112, so that the first pre-welded part of the third tank 113 in the first tank 111 and the second pre-welded part of the first tank 111 are welded, or the first pre-welded part of the third tank 113 in the second tank 112 and the second pre-welded part of the second tank 112 are welded.

[0094] In some embodiments, the second welding apparatus 6 includes a second moving component 62 and a second laser welding component 61; the second moving component 62 drives the second laser welding component 61 to perform laser welding.

[0095] Specifically, the second welding device 6 can be an existing automated welding device. The second welding device 6 includes a second moving component 62, which may include a robotic arm mechanism. Its structure can be identical to that of the first robotic arm 231, and will not be described in detail here. The second laser welding component 61 is positioned on the free end of the robotic arm and moves to perform welding. The second laser welding component 61 only welds the first tank 111 or the second tank 112, so that the first pre-welded part of the third tank 113 within the first tank 111 is welded to the second pre-welded part of the first tank 111, or the first pre-welded part of the third tank 113 within the second tank 112 is welded to the second pre-welded part of the second tank 112. The second laser welding component 61 is equipped with a vision module, such as a CCD or camera, which is used to assist in the movement and welding of the laser welding head. The first and second welding devices only weld the first tank 111 or the second tank 112, so that the first pre-welded part of the third tank 113 in the first tank 111 and the second pre-welded part of the first tank 111 are welded, or the first pre-welded part of the third tank 113 in the second tank 112 and the second pre-welded part of the second tank 112 are welded.

[0096] In some embodiments, the flipping device 5 includes a lifting and traversing mechanism 51 and an adsorption and rotation mechanism 52; the adsorption and rotation mechanism 52 adsorbs and flips the second pre-welded part of the first tank 111, and the lifting and traversing mechanism 51 adsorbs and moves the flipped second pre-welded part into the second tank 112; the adsorption and rotation mechanism 52 includes a rotating motor 521 and a fourth adsorption head 523; the rotating motor 521 is provided with a rotating shaft 522, which is disposed above the support member 11, and the fourth adsorption head 523 is disposed on the rotating motor 521. The drive shaft rotates around the rotating shaft 522 to allow the fourth adsorption head 523 to adsorb the second pre-welded part and flip it over; the lifting and traversing mechanism 51 includes a fourth moving guide rail 511, a fourth lifting guide rail 512, a fifth adsorption head 513 and a flipping bracket 514. The fourth lifting guide rail 512 is vertically arranged on the fourth moving guide rail 511 and moves. The fifth adsorption head 513 is arranged on the fourth lifting guide rail 512 and moves up and down so that the fifth adsorption head 513 can move above the fourth adsorption head 523 and be aligned with the fourth adsorption head 523 for adsorption.

[0097] Specifically, the adsorption rotation mechanism 52 includes a rotation motor 521 and a fourth adsorption head 523. The rotation motor 521 is equipped with a rotation shaft 522, which is positioned above the support member 11. The fourth adsorption head 523 is mounted on the drive shaft of the rotation motor 521 and rotates around the rotation shaft 522. Specifically, the fourth adsorption head 523 can rotate to a position directly above the second pre-welded part of the support member 11 and adsorb it. After adsorption, it can rotate around the rotation shaft 522 until the other side of the adsorption surface of the second pre-welded part is facing upwards. Furthermore, the fourth adsorption head 523 can be equipped with a forward pushing structure to push the fourth adsorption head 523 away from the rotation shaft 522, thereby avoiding rotational collisions with the support member 11 and causing wear and damage to the structure.

[0098] The flipping device 5 includes a lifting and traversing mechanism 51, which can be mounted on the fourth support 53. A fourth moving seat is mounted on the fourth moving guide rail 511. A fourth lifting guide rail 512 is fixed vertically, and a fourth lifting seat (not shown in the figure) is mounted on the fourth lifting guide rail 512. The fourth moving guide rail 511 can be equipped with a chain belt to move the fourth moving seat, or it can be a linear motor structure for movement, which is not limited here. This allows the fifth adsorption head 513 to move up and down and traverse laterally via the fourth lifting seat. The length of the fourth moving guide rail 511 must at least exceed the width of the bearing member 11, i.e., exceed the combined width of the first groove 111 and the second groove 112, to enable movement between the first groove 111 and the second groove 112 of the second pre-welded component. The shells of the fourth adsorption head 523 and the fifth adsorption head 513 are designed with specific structures according to the actual structure of the second pre-welded component, or are modules composed of multiple adsorption heads.

[0099] Normally, the height of the lifting and traversing mechanism 51 is higher than the height of the adsorption and rotation mechanism 52. In actual flipping operations, if the first welding device 4 is welding the second pre-welded part located in the first tank 111, the adsorption and rotation mechanism 52 is positioned above the first tank 111 so that the fourth adsorption head 523 can adsorb the second pre-welded part and detach it from the first tank 111, with the side of the second pre-welded part welded to the first pre-welded part facing upwards. At this time, the lifting and traversing mechanism 51 can drive the fifth adsorption head 513 to move horizontally to directly above the second pre-welded part and lower the fifth adsorption head 513 to the other surface adsorbed by the fourth adsorption head 523. After the fifth adsorption head 513 adsorbs the second pre-welded part and the fourth adsorption head 523 releases its adsorption and detaches from the second pre-welded part and resets, the fifth adsorption head 513 adsorbs the second pre-welded part that has been flipped 180°, moves it horizontally above the second tank 112, and lowers it for placement. Furthermore, to achieve accuracy in the steps, a vision module is usually required to assist in movement and positioning.

After the transfer mechanism 75 aligns the second pre-welded component, it is moved by the unloading mechanism 71 to the carrier that is not loaded with the second pre-welded component. The second carrier moving mechanism 72 moves the carrier fully loaded with the second pre-welded component to the second carrier recovery area 74. The transfer mechanism 75 includes a transfer table 755, a transfer guide rail 751, a transfer lifting claw 753, and a vision sensor 754.

The fifth lifting part 722 is vertically mounted on the fourth moving guide rail 511 and moves. The seventh suction head 723 is mounted on the fifth lifting part 722 and moves up and down to suction the carrier.

[0101] Specifically, the transfer platform 755 of the transfer mechanism 75 is located between the unloading mechanism 71 and the carrier 11, and is configured to transfer the second pre-welded part. This avoids damage caused by excessively long transfer stroke of the second pre-welded part. Simultaneously, the position of the second pre-welded part can be adjusted through the transfer mechanism 75, allowing it to enter the carrier in a fixed position, saving adjustment time. The transfer platform 755 has a transfer groove 756 with the shape and position of the second pre-welded part, ensuring that the second pre-welded part is placed and removed in a fixed position when inserted into the groove 756. A vision sensor 754, such as an auxiliary CCD or camera, is provided around the transfer groove 756 to assist the second pre-welded part in entering the groove 756. The transfer lifting claw 753 moves laterally on the transfer guide rail 751, which is mounted on the transfer bracket 752, allowing the transfer lifting claw 753 to move and adjust above the carrier 11 and the transfer groove 756. The adapter lifting claw 753 can be a clamping or adsorption structure, so that the second pre-welded part can move with the adapter lifting claw 753.

Furthermore, a CCD, camera, and vision module can be configured to locate the carrier position and perform precise gripping. The fifth moving guide rail 721 can be equipped with a chain belt to move the fourth moving seat, or it can be a linear motor structure for movement; this is not limited.
