Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a multi-axis welding device. Background Technology

[0002] As a core component of electronic devices, the soldering quality of circuit boards is crucial. In current circuit board production, numerous electronic components need to be fixed to the board by soldering. Traditional manual soldering involves workers using both hands to hold a soldering gun and solder bars, resulting in extremely strenuous operation and low efficiency. Although multi-axis soldering machines exist on the market to replace manual labor, many problems remain, such as excessively high surface temperatures on the circuit board during soldering, which can easily damage internal components; some machines have integrated component designs, making repair and replacement inconvenient after damage; and some have limited soldering range, with inflexible angle and position adjustments, making it difficult to meet the soldering needs of complex circuit boards.

[0003] Chinese Patent Publication No. CN116275770A discloses a utility model of a multi-axis contour welding device and method. The device includes: a spliced ​​guide rail with a shape matching the welding trajectory; a guide rail traveling mechanism including a base, a traveling wheel set, and a driving component for driving the traveling wheel set along the guide rail; a horizontal moving mechanism including a driving base, a horizontal moving shaft, and a first force-applying pulley set, the first force-applying pulley set applying a thrust to the horizontal moving shaft; a vertical floating mechanism including a vertical floating shaft seat, a vertical floating shaft, and a contouring seat; a horizontal swinging mechanism including a horizontal swinging seat; and a horizontal floating mechanism including a horizontal floating shaft, a horizontal floating shaft seat, and a second force-applying pulley set, the second force-applying pulley set applying a thrust to the horizontal floating shaft. This invention can control the contouring effect of the welding torch on the horizontally welded object in the vertical direction and on the vertically welded object in the horizontal direction, realizing multi-axis contour welding of complex-shaped workpieces and effectively improving the automation level and efficiency of welding irregular steel structural parts.

[0004] Most circuit board welding machines on the market currently use a fixed welding mode. In this mode, the operation process involves multiple cumbersome steps, requiring a high level of operator proficiency. This not only increases training costs but also makes it easy for operational errors to affect the welding process. At the same time, since the circuit board cannot be moved flexibly during welding, workers need to frequently manually adjust the position of the circuit board. This process is time-consuming and labor-intensive, and repetitive operations lead to a significant reduction in welding efficiency. Furthermore, the fixtures used in the fixed welding mode often apply great pressure to the circuit board to ensure stability, which can easily cause cracks, deformations, and other damage to the circuit board during clamping, thus directly affecting the quality and stability of the final product.

[0005] Therefore, we propose a multi-axis welding device to solve the above problems. Utility Model Content

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Reference Figure 1-5 A multi-axis welding device includes a base 1. Multi-axis moving mechanisms 2 are provided on both sides of the top of the base 1. By rotating different parts of the multi-axis moving mechanisms 2, the circuit board can be flipped and displaced at different angles. Clamping fixtures 3 are fixedly connected to one side of each of the two multi-axis moving mechanisms 2. A detachable rubber pad (not shown) is installed at the top of the clamping distance from the base. This serves to protect the circuit board and increase the height of the circuit board so that it can contact the clamping mechanism 4. Clamping mechanism 4 is provided on the top of the inner surface of each of the two clamping fixtures 3. The clamping mechanism 4 can effectively reduce damage to the circuit board. A welding mechanism 7 is provided on one side of the top of the base 1 to facilitate welding operations by the operator. The multi-axis moving mechanism 2 includes a support plate 201, the bottom of which is fixedly connected to the top of the base 1. A moving plate 202 is provided on one side of the support plate 201. A rotating shaft 205 is provided between the support plate 201 and the moving plate 202. The rotating shaft 205 is rotatably connected to the support plate 201 and the moving plate 202 via a rotating shaft. The rotating shaft 205 passes through the support plate 201, thereby realizing the movement of the moving plate 202. A rotating shaft 203 is rotatably connected to the top of the moving plate 202 via a rotating shaft. The rotating shaft 203 passes through the moving plate 202. A rotating block 204 is fixedly connected to one side of the rotating shaft 203, thereby realizing the rotation of the rotating block 204. A clamping device 3 is fixedly connected to one end of the rotating block 204 for clamping the circuit board.

[0020] Furthermore, the clamping mechanism 4 includes a hydraulic pump 401. The top of the hydraulic pump 401 is fixedly connected to the top of the inner surface of the clamping fixture 3 to fix the hydraulic pump 401. A disc 405 is fixedly connected to the bottom of the hydraulic pump 401. A sleeve 402 is sleeved on the outer side of the telescopic part of the hydraulic pump 401. A rubber pad (not shown) is installed on the disc 405 to ensure the airtightness of the sleeve 402 during the operation of the hydraulic pump 401. The top of the sleeve 402 is fixedly connected to the hydraulic pump 401. A suction cup 403 is fixedly connected to the bottom of the sleeve 402. The suction cup 403 is made of soft rubber to avoid damage when adsorbing the circuit board. A through hole 404 is opened on the top of the suction cup 403. When the hydraulic pump 401 is working, the movement of the disc 405 creates a negative pressure inside the sleeve 402 to firmly adsorb the circuit board.

[0021] Furthermore, the welding mechanism 7 includes a support base 701, the bottom of which is fixedly connected to the top of the base 1. The tops of both sides of the support base 701 are rotatably connected to linkage plates 702 via rotating shafts. A support column 703 is provided between adjacent linkage plates 702. The support column 703 is rotatably connected to the linkage plate 702 via a rotating shaft. A welder 704 is fixedly connected to the top of the support column 703. By rotating the linkage plate 702 and the support column 703, the different positions of the welder 704 can be adjusted to meet the welding requirements of different positions.

[0022] Furthermore, a first drive motor 5 is provided on one side of the rotating shaft 205. The output end of the first drive motor 5 is connected to the extension end of the rotating shaft 205 through a linkage. When the first drive motor 5 is started, it can drive the rotating shaft 205 to rotate, thereby causing the moving plate 202 to move.

[0023] Furthermore, a second drive motor 6 is provided on one side of the rotating shaft 203. The output end of the second drive motor 6 is connected to the extension end of the rotating shaft 203 through a linkage. When the second drive motor 6 is started, it can drive the rotating shaft 203 to rotate, thereby causing the rotating block 204 to rotate, thus changing the position of the clamp 3.

[0024] Specifically, the support frame of the first drive motor 5 is fixedly connected to the support plate 201 by bolts, and the support frame of the second drive motor 6 is fixedly connected to the moving plate 202 by bolts, thereby fixing the first drive motor 5 and the second drive motor 6 to ensure that the device can operate normally.

[0025] In summary: First, the operator installs a rubber pad on the bottom of the clamp 3 to protect the circuit board and raise it so that it can contact the suction cup 403. Then, the circuit board is inserted from the bottom of the clamp 3 and the side of the suction cup 403. Subsequently, the hydraulic pump 401 is started, causing its telescopic part to extend and retract. Since a sealed cavity is formed between the circuit board, the suction cup 403, and the sleeve 402 through the through hole 404, when the disc 405 rises with the hydraulic pump 401, the space volume increases, creating a negative pressure inside the cavity. This fixes the circuit board while preventing damage during clamping. Then, the operator starts the first drive motor 5 and the second drive motor 6, and adjusts the multi-axis moving mechanism 2 to bring the circuit board to the expected position. Finally, the operator manually moves the support column 703, causing the welder 704 to act on the circuit board, thereby welding the circuit board.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
