[0033] Some embodiments of the present application will be described in detail with reference to the drawings. The following embodiments and features described below can be combined with each other in the case of no conflict.

[0034] Embodiment 1

[0035] Reference Figure 1 As shown in the drawings, the embodiments of the present application provide a conveying device 100, which comprises a rack 110, a wire feeding assembly 120, a first adjusting assembly 130 and a driving assembly 140.

[0036] Specifically, in combination with Figure 2 and Figure 3 As shown in the drawings, the wire feeding assembly 120 comprises a first wire feeding wheel 121 and a second wire feeding wheel 122. The first wire feeding wheel 121 is mounted on the rack 110, and the first wire feeding wheel 121 and the second wire feeding wheel 122 are oppositely arranged. The welding wire is clamped in the gap between the first wire feeding wheel 121 and the second wire feeding wheel 122.

[0037] In the present embodiment, the first adjusting assembly 130 comprises a connecting piece 131 and a first adjusting piece 132. The connecting piece 131 is movably connected with the rack 110 through the first adjusting piece 132, and the connecting piece 131 is connected with the second wire feeding wheel 122, so that the first adjusting piece 132 drives the second wire feeding wheel 122 to move close to or away from the first wire feeding wheel 121 through the connecting piece 131.

[0038] The driving assembly 140 is connected with the first wire feeding wheel 121, and the driving assembly 140 drives the first wire feeding wheel 121 to rotate, so that the first wire feeding wheel 121 drives the welding wire to perform the wire feeding operation. The first wire feeding wheel 121 is mounted on the rack 110, and when the first adjusting piece 132 drives the connecting piece 131 to move relatively, the second wire feeding wheel 122 connected with the connecting piece 131 moves close to or away from the first wire feeding wheel 121. At this time, the first wire feeding wheel 121 remains stationary, so as to achieve the purpose of adjusting the position of the second wire feeding wheel 122. The pressure for clamping the welding wire between the first wire feeding wheel 121 and the second wire feeding wheel 122 changes, which reduces the situation that the welding wire is crushed and stuck due to excessive pressure between the first wire feeding wheel 121 and the second wire feeding wheel 122, or reduces the situation that the welding wire slips due to insufficient pressure between the first wire feeding wheel 121 and the second wire feeding wheel 122.

[0039] In combination with Figures 1 to 3As shown, the conveying device 100 has a first direction X, a second direction Y and a third direction Z, wherein the first direction X, the second direction Y and the third direction Z are perpendicular to each other. For example, the first direction X is in the width direction of the conveying device 100, the second direction Y is in the length direction of the conveying device 100, and the third direction Z is in the height direction of the conveying device 100. It can be understood that the above definitions are only for the convenience of understanding the relative position relationship of each part in the conveying device 100, and should not be understood as a limitation of the present application.

[0040] For example, the first wire feeding wheel 121 and the second wire feeding wheel 122 are both gear structures, and the teeth part in the gear structure adopts a triangular tooth structure. The triangular tooth structure has smaller friction loss and higher transmission efficiency. When the wire feeding wheel abuts against the welding wire, the pressure on the welding wire is increased, a small indentation is formed on the surface of the welding wire, the wire feeding slip phenomenon is not easy to occur, the precision of conveying the welding wire is ensured, the welding wire is driven to move, and the welding wire is clamped through the gap between the two wire feeding wheels and can smoothly pass through the wire feeding pipe 170 for conveying.

[0041] It can be understood that when the gap between the first wire feeding wheel 121 and the second wire feeding wheel 122 is too large, the first wire feeding wheel 121 and the second wire feeding wheel 122 cannot effectively clamp the welding wire, which is insufficient to drive the welding wire to move, resulting in the welding wire slipping during the wire feeding process. In addition, when the gap between the first wire feeding wheel 121 and the second wire feeding wheel 122 is too small, the first wire feeding wheel 121 and the second wire feeding wheel 122 clamp the welding wire too tightly, resulting in the welding wire being stuck and unable to continue conveying during the wire feeding process.

[0042] In one embodiment, optionally, referring to Figure 2 and Figure 3 As shown, the rack 110 includes a rack body 111 and a fixing member 112, and one end of the connecting member 131 is rotationally connected to the rack body 111 through a rotating shaft 133. As shown in Figure 4 The end of the connecting member 131 away from the rotating shaft 133 is provided with a mounting hole 1312a. The first adjusting member 132 penetrates the mounting hole 1312a, and the first adjusting member 132 is movably connected with the fixing member 112. Correspondingly, the first adjusting member 132 moves relative to the fixing member 112 through the mounting hole 1312a of the connecting member 131, and drives the connecting member 131 to move through the first adjusting member 132. The connecting member 131 rotates relative to the rack body 111 through the rotating shaft 133, so that the connecting member 131 drives the second wire feeding wheel 122 to move close to or away from the first wire feeding wheel 121. Further, the first adjusting member 132 is an adjusting screw, and the first adjusting member 132 is threadedly connected with the fixing member 112. For example, the fixing member 112 is a fixed plate, and the fixed plate is integrally provided with the rack body 111.

For example, the first elastic member 134 is a constant pressure spring or a return spring.

Accordingly, when the position of the second wire feeding wheel 122 is adjusted, the second wire feeding wheel 122 is abutted with the welding wire to limit the feeding of the welding wire. The first sensing member 1311 can receive the real-time pressure between the second wire feeding wheel 122 and the welding wire through the first adjusting plate 1312, and adjust the position of the second wire feeding wheel 122 according to the real-time pressure between the second wire feeding wheel 122 and the welding wire, so as to reduce the situation that the second wire feeding wheel 122 and the welding wire are stuck due to excessive pressure, or reduce the situation that the second wire feeding wheel 122 and the welding wire slip due to insufficient pressure, thereby achieving a better technical effect. For example, the first sensing member 1311 is a pressure sensor, which can transmit the received pressure value to the controller output, so that personnel can adjust the position of the second wire feeding wheel 122 according to the pressure value.

[0045] Optionally, the first adjusting plate 1312 is provided with a mounting groove 1312b, the second adjusting plate 1313 is accommodated in the mounting groove 1312b, and the second wire feeding wheel 122 is at least partially located in the mounting groove 1312b, so as to reasonably utilize the assembly space of the second adjusting plate 1313, thereby achieving high space utilization. The second adjusting plate 1313 can be installed in the mounting groove 1312b of the first adjusting plate 1312, and the first sensing member 1311 is fixed and limited by the second adjusting plate 1313 and the mounting groove 1312b of the first adjusting plate 1312, thereby reducing the situation that the first sensing member 1311 deviates or is misaligned during use.
