Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a welding device and a pre-welding machine for wire mesh surfboards. Background Technology

[0002] Multilayer blanks are composed of two or more material layers combined together in different ways. In related technologies, multilayer blanks have flat sides and raised sides. Because the raised sides are raised, it is difficult to position them during the welding process of multilayer blanks, resulting in welding position misalignment.

[0003] For example, in the welding process of a brushed fabric surfboard, the multi-layer blank includes an upper layer and a lower layer. On the flat side, the upper and lower layers are of the same length, while on the curved side, the lower layer is longer than the upper layer. During the manufacturing of the brushed fabric surfboard, because the front and rear structures are not perfectly regular, the friction between the upper and lower layers and the rollers on the welding machine is different. This results in poor positioning of the multi-layer blank by the welding device, making it difficult to align the upper and lower layers and affecting the pre-welding accuracy. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a welding device that has the advantages of high welding precision and low risk of misalignment of multi-layer blanks.

[0017] According to some embodiments of the present invention, the welding device includes a transmission mechanism comprising a first roller, a second roller, and two power elements. The first roller and the second roller radially form a conveying channel for the multi-layered blank. The two power elements can respectively drive the first roller and the second roller to rotate, thereby pressing and moving the multi-layered blank.

[0018] According to some embodiments of the welding apparatus of the present invention, a second pressure rod is provided on one side of the transmission mechanism along the transmission direction of the multilayer blank. The second pressure rod is horizontally arranged perpendicular to the transmission direction of the multilayer blank and is used to press against the multilayer blank.

[0033] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0038] Multi-layer preforms consist of two or more layers of material combined in different ways. In related technologies, multi-layer preforms have flat and raised sides. Because the raised side is upturned, positioning is difficult during the welding process, leading to welding position misalignment. For example, pre-welding machines for brushed fabric surfboards are mainly used to pre-weld the upper and lower layers of brushed fabric to prevent translational misalignment between the two layers. However, current pre-welding machines for brushed fabric surfboards have poor positioning of the raw materials, making it difficult to align the upper and lower brushed fabric layers, resulting in poor pre-welding performance.

[0039] Therefore, one embodiment of this utility model provides a welding device, as detailed in the accompanying drawings. Figures 1 to 5 As shown.

[0040] A welding apparatus according to one embodiment of this utility model includes a frame 100, a positioning mechanism 200, a welding head 300, and a transmission mechanism 400. The frame 100 is provided with a worktable 110 for placing multi-layer blanks. The positioning mechanism 200 is disposed on the frame 100 and is used to fix the multi-layer blanks, effectively preventing problems such as displacement and misalignment of the multi-layer blanks during the welding process. The welding head 300 is connected to the frame 100 and located above the worktable 110. The welding head 300 can move up and down toward the worktable 110 and is used to weld the flat side of the multi-layer blanks. The transmission mechanism 400 is installed on the frame 100 and located at one end of the worktable 110. One end of the multi-layer blank passes through the transmission mechanism 400, which is used to transport the multi-layer blanks and cooperates with the welding head 300 to weld the raised side of the multi-layer blanks. The multi-layer blank is placed on the worktable 110. The flat side is pre-welded by the welding head 300, and then moved to the transmission mechanism 400 for pre-welding of the curved side. Welding the flat side first can pre-fix the upper and lower layers of fabric in the multi-layer blank, avoiding translational misalignment between the two layers, thereby reducing the risk of misalignment between the two layers of fabric in the multi-layer blank and improving the accuracy of the welding point.

[0041] Specifically, in one embodiment of the welding device of this utility model, a pressure foot 320 is sleeved around the welding head 300. The pressure foot 320 is connected to an elastic element and is slidably disposed on the welding head 300 along the center line of the welding head 300. The movement of the welding head 300 drives the pressure foot 320 to move, and the pressure foot 320 can extend out of the welding head 300 to press against the multi-layer blank. During welding, the welding head 300 moves downward. Since the pressure foot 320 extends out of the welding head 300, it will contact the multi-layer blank before the welding head 300. Under the action of the elastic element, the pressure foot presses against the pre-welding position of the multi-layer blank to level the multi-layer blank, providing a flat welding surface for the subsequent welding work of the welding head 300, ensuring more accurate welding positioning, and greatly improving the welding quality.

[0042] A welding apparatus according to an embodiment of the present invention, referring to... Figure 3 and Figure 5 As shown, the welding head 300 is equipped with a second drive member 340 and a third drive member 310. A crossbeam 330 is slidably mounted on the frame 100 along a direction parallel to the conveying direction of the multi-layer blank. The welding head 300 is mounted on the crossbeam 330, which is horizontally positioned perpendicular to the conveying direction of the multi-layer blank. The crossbeam 330 can slide relative to the worktable 110, thereby moving the welding head 300. This allows the welding head 300 to be precisely moved to any position on the blank, thus meeting welding requirements. The second drive member 340, the third drive member 310, and the welding head 300 are all mounted on the crossbeam 330. The second drive member 340 drives the welding head 300 to slide along a direction perpendicular to the conveying direction of the multi-layer blank. When welding the edges of the multi-layer blank, the lateral position of the welding head 300 can be precisely adjusted according to the shape of the edge and welding requirements, ensuring a uniform and strong weld and improving welding quality. The third drive unit 310 drives the welding head 300 to move up and down toward the worktable 110. The third drive unit 310 controls the welding head 300 to descend, ensuring that the welding head 300 can accurately contact the multi-layer blank, and with the cooperation of the pressure foot 320, realize the welding of the multi-layer blank. After welding is completed, the welding head 300 can be quickly raised to prepare for the next welding operation.

[0043] In some embodiments, the second drive member 340 and the welding head 300 can be connected by chain drive or by screw drive. There are no specific restrictions on the connection method between the second drive member 340 and the welding head 300, as long as the transmission efficiency and accuracy of welding are met.

[0044] In some embodiments of this utility model, reference is made to... Figure 1 and Figure 4 As shown, the positioning mechanism 200 includes a first pressure rod 210 and a first driving member 220. The first pressure rod 210 is arranged perpendicular to the conveying direction of the multi-layer blank. The first driving member 220 is used to drive the first pressure rod 210 to fix or release the multi-layer blank. The first driving member 220 is a quick clamp; simply moving the quick clamp allows the first pressure rod 210 to quickly fix or release the multi-layer blank, simplifying operation and significantly reducing operation time. During the transmission of the multi-layer blank, the first pressure rod 210 can flatten the multi-layer blank, ensuring a tight fit between the upper and lower layers and preventing welding misalignment due to unevenness, thus making the welding process more efficient, stable, and reliable.

[0045] In some embodiments of this utility model, reference is made to... Figure 1 , Figure 3 and Figure 5As shown, the welding head 300 includes a first welding head 301 and a second welding head 302, which are respectively arranged on both sides of the multi-layer blank for simultaneous welding of both sides of the blank. There are two second driving members 340 and two third driving members 310. The two second driving members 340 drive the first welding head 301 and the second welding head 302 to slide along a direction perpendicular to the conveying direction of the multi-layer blank, respectively. The two third driving members 310 drive the first welding head 301 and the second welding head 302 to move up and down toward the worktable 110, respectively. The second driving members 340 and the third driving members 310 can flexibly adjust the positional relationship between the welding head 300 and the multi-layer blank to meet the requirements of different welding process parameters and ensure welding accuracy. The first welding head 301 and the second welding head 302 are arranged alternately to weld both sides of the multi-layer blank. The first welding head 301 and the second welding head 302 can simultaneously weld both sides of the multi-layer blank, improving welding efficiency and ensuring the synchronicity and consistency of welding on both sides of the multi-layer blank, thereby improving the overall welding quality.

[0046] It should be noted that in some embodiments of this utility model, the welding head 300 is also provided with a positioning element 350, which is an infrared sensor. The infrared sensor is used to guide the welding head 300, and the point indicated by the infrared sensor is the welding point of the welding head 300. The positioning element 350 is accurately positioned, which significantly improves the quality and precision of welding.

[0047] Furthermore, in some embodiments of this utility model, the welding head 300 is equipped with a mechanical switch to prevent the welding head 300 from colliding with the transmission mechanism 400. After the welding head 300 completes the welding process on the flat side of the multi-layer blank, it moves to the transmission mechanism 400 to weld the curved side of the multi-layer blank. The mechanical switch ensures that the welding head 300 is in its initial position during movement, preventing the welding head 300 from colliding with the transmission mechanism 400 during the movement, thus ensuring the normal operation of the welding head 300 and avoiding damage caused by collision.

[0048] In some embodiments of this utility model, reference is made to... Figure 1 and Figure 2 As shown, a brush rod 410 is provided between the transmission mechanism 400 and the positioning mechanism 200, and the brush rod 410 is arranged perpendicular to the conveying direction of the multi-layer blank. Since the upper and lower layers of the multi-layer blank have different lengths, the brush rod 410 can push the length difference of the raised side to the back when welding the raised side of the multi-layer blank. This facilitates the differential transmission of the multi-layer blank by the transmission mechanism 400, making the raised side of the multi-layer blank flatter during welding.

[0049] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2As shown, the transmission mechanism 400 includes a first roller 420, a second roller 430, and two power elements 440. The first roller 420 and the second roller 430 radially form a conveying channel for the multi-layer blanks, effectively ensuring the stability of the multi-layer blanks during the conveying process and preventing the multi-layer blanks from shifting. The two power elements 440 can drive the first roller 420 and the second roller 430 to rotate, thereby pressing and moving the multi-layer blanks. It should be noted that the differential transmission of the first roller 420 and the second roller 430 helps to ensure that the upper and lower layers of blanks remain flat and tightly fitted during the conveying process, thereby improving the accuracy of the welding position. In other embodiments, the first roller 420 and the second roller 430 can also be driven at the same speed. Depending on the actual application scenario and requirements, the transmission speed of the first roller 420 and the second roller 430 can be flexibly adjusted.

[0050] In some embodiments of this utility model, reference is made to Figure 1 and Figure 2 As shown, a second pressure rod 450 is provided on one side of the transmission mechanism 400 along the transmission direction of the multi-layer blank. The second pressure rod 450 is horizontally arranged perpendicular to the transmission direction of the multi-layer blank, which can uniformly apply pressure to the multi-layer blank. The second pressure rod 450 is used to press down on the multi-layer blank. In some application scenarios, after the welding head 300 completes the welding of the flat side of the multi-layer blank, it slides to the side of the transmission mechanism 400 away from the positioning mechanism 200. The transmission mechanism 400 conveys the multi-layer blank towards the welding head 300 and presses down on the multi-layer blank through the second pressure rod 450 to prevent the multi-layer blank from warping during transmission.

[0051] The pre-welding machine for brushed fabric surfboards according to an embodiment of the present invention includes a welding device according to an embodiment of the present invention.

[0052] The pre-welding machine for brushed fabric surfboards according to this utility model, by employing the welding device of this utility model, can effectively prevent the two layers of fabric from shifting or misaligning during subsequent processing, reducing the risk of misalignment and improving the stability of pre-welding. The welding sequence of first flattening the side and then raising the side significantly improves the accuracy of the welding points, resulting in brushed fabric surfboards with superior quality and performance, making them more competitive in the market.

[0053] Other components and operations of the pre-welding machine for wire mesh surfboards according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
