Description

Technical Field

[0001] The utility model relates to the field of laser welding equipment, in particular to a double-head laser spot welding equipment. Background Art

[0002] Laser spot welders are commonly used for welding products such as FPCs, PCBs, LED displays, flat cables, and terminals. They are machines used for laser welding during material processing. Laser welding machines also include galvanometer welders. Galvanometer welding is an emerging welding method also known as vibration friction welding or vibration friction stir welding.

[0003] In the existing technology, laser spot welding machines generally adopt a single-head, single-sided welding structure, and only weld a single welding position of the material. When welding operation is required on the other side, it needs to be flipped over. Not only is the efficiency low, but the robot arm used for flipping is usually complex in structure, occupies a lot of space, and is not conducive to maintenance.

[0004] In view of this, this technical solution proposes a double-head laser spot welding equipment, which is equipped with a carrier that can automatically rotate the material and multiple stations on the carrier to achieve synchronous and asynchronous welding up and down, which directly improves the welding processing efficiency. It also has auxiliary mechanisms such as positioning and fine-tuning to achieve accurate and efficient welding processing. Utility Model Content

The first welding body is arranged above the material loading turntable, and the second welding body is arranged below the material loading turntable. A positioning assembly is provided between the first welding body and the second welding body.

[0008] The positioning assembly includes a first pressure head group and a second pressure head group respectively located on the upper and lower sides of the loading turntable. The first pressure head group and the second pressure head group are pressed and fixed on both sides of the loading turntable through an opening and closing cylinder arranged on one side. The first weldment body and the second weldment body respectively pass through the middle gap of the first pressure head group and the second pressure head group for laser welding.

[0009] As a further solution of the present invention, the first pressure head group and the second pressure head group each include at least two pressure heads arranged side by side.

[0010] As a further solution of the present invention, the first pressure head group and the second pressure head group are both detachable and replaceable pressing members, and the pressing members are connected to a mounting seat on one side for fixing via detachable screws.

[0011] As a further solution of the present invention, the double-head welding assembly also includes a control box for controlling the main macro distance of the first weldment body and the second weldment respectively. The control box is connected to the fine-tuning mechanism on one side of the welding equipment body, and the fine-tuning mechanism is a fine-tuning crank.

[0012] As a further solution of the present invention, the alignment component is provided with a laser alignment device for performing plane calibration.

[0013] As a further solution of the present invention, the loading turntable is a four-station turntable structure driven to rotate by a motor.

[0014] The beneficial effects of the utility model are as follows:

[0015] This dual-head laser spot welding system utilizes a turntable and a dual-head welding assembly with an alignment component to achieve automatic material transport and synchronous (or asynchronous) double-sided welding.

[0022] as follows:

[0023] Please see the attached Figure 1-4 ,

[0024] The main structure includes a welding equipment body 1 consisting of a double-head welding assembly 10 and a loading turntable 11. The double-head welding assembly 10 consists of a first weldment body 100 and a second weldment body 101. The first weldment body 100 is arranged above the loading turntable 11, and the second weldment body 101 is arranged below the loading turntable 11. A positioning assembly 2 is provided between the first weldment body 100 and the second weldment body 101. The positioning assembly includes a first pressure head group 21 and a second pressure head group 22 respectively located on the upper and lower sides of the loading turntable 11. The first pressure head group 21 and the second pressure head group 22 are pressed and fixed on both sides of the loading turntable 11 through an opening and closing cylinder 20 arranged on one side. The first weldment body 100 and the second weldment body 101 pass through the middle gap of the first pressure head group 21 and the second pressure head group 22 respectively for laser welding.

[0025] Here's how it works:

[0026] During operation, the material 3 to be welded 30 is placed on the loading turntable 11. The loading turntable 11 rotates the material 3 to the corresponding positions of the first weldment body 100 and the second weldment body 101 for welding. At this time, the two pressure heads of the positioning component 2 (the first pressure head group 21 and the second pressure head group 22) press down on the weldment 30 to make it stable. The first weldment body 100 and the second weldment body 101 (or asynchronously) pass through the gap between the first pressure head group 21 and / or the second pressure head group 22 to weld the weldment 30. After welding, they reset and start the next cycle.

[0027] In a preferred embodiment of the present invention, the first pressure head group 21 and the second pressure head group 22 each include at least two pressure heads arranged side by side.

[0028] Two side-by-side pressing heads can simultaneously press down two parts 30 to be welded, reducing the need for back-and-forth movement of the pressing heads and improving efficiency. Furthermore, considering that some current battery cells, for example, generally have two parts 30 to be welded on their package heads, two side-by-side pressing heads can simultaneously press down two parts 30 to be welded.

[0029] In a preferred embodiment of the present invention, the first pressing head group 21 and the second pressing head group 22 are both detachable and replaceable pressing members, which are connected to a mounting seat 23 on one side for fixing via detachable screws.

[0030] In order to adapt to the specifications of different materials 3 and workpieces 30 to be welded, first pressing head groups 21 and second pressing head groups 22 of different sizes and thicknesses are used.

[0031] A preferred embodiment of the present invention: the double-head welding assembly 10 also includes a control box 102 for controlling the main macro distance of the first weldment body 100 and the second weldment, respectively. The control box 102 is connected to a fine-tuning mechanism 103 on one side of the welding equipment body 1, and the fine-tuning mechanism 103 is a fine-tuning crank.

[0032] The crank is used to fine-tune the welding head, which is suitable for scenarios that require precise and personalized welding.

[0033] A preferred embodiment of the present invention: the alignment component 2 is provided with a laser alignment device for plane calibration.

[0034] A preferred embodiment of the present invention is that the loading turntable 11 is a four-station turntable structure driven by a motor.

[0035] The multi-station loading turntable 11 has multiple processing modes, such as single rotation welding, or stacked alternating welding, and is suitable for various product processing requirements.

[0036] The above are only preferred embodiments of the technical solution of the present utility model, and do not limit the patent scope of the technical solution of the present utility model. All equivalent structural transformations made by using the contents of the description and drawings of the technical solution of the present utility model under the conception of the technical solution of the present utility model, or direct / indirect application in other related technical fields are included in the patent protection scope of the technical solution of the present utility model.
