[0042] The specific implementation of the embodiment of the utility model is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the utility model, and is not used to limit the embodiment of the utility model.

[0043] Figure 1 It is a structural schematic diagram of a welding device for welding a double-layer sealing strip according to an embodiment of the utility model; Figure 2 is based on Figure 1 A magnified schematic diagram of the middle A area; Figure 3 Schematic diagram of the structure of the auxiliary support device for double-layer sealing strip welding according to one embodiment of the utility model. Figure 1 , Figure 2 and Figure 3 In the embodiment, the auxiliary support device may include a base 3, two groups of first support plates 9, two groups of second support plates 17 and a driving assembly.

[0044] The base 3 is arranged at the mold entry side of the sealing strip welding machine 1, and two groups of first support plates 9 are symmetrically arranged on two opposite side walls of the base 3, and the tops of the two groups of first support plates 9 are higher than the top of the base 3. Two groups of second support plates 17 are symmetrically arranged on the other two opposite side walls of the base 3, and the driving assembly is connected to the two groups of second support plates 17, and is used to drive the two groups of second support plates 17 to rotate close to and cooperate to form a support plane with a height higher than the tops of the two groups of first support plates 9.

[0045] When the robot grabs the sealing strip 2 of the lower layer and puts it into the mold, the tops of the two groups of first support plates 9 form a lower support plane, and support the mold section of the sealing strip 2 of the lower layer to ensure that the sealing strip 2 of the lower layer can be stably put into the mold. When the robot grabs the sealing strip 2 of the upper layer and puts it into the mold, the drive component starts, driving the two groups of second support plates 17 to rotate synchronously and approach each other until the side walls fit together. At this time, the two groups of second support plates 17 cooperate to form an upper support plane, and support the mold section of the sealing strip 2 of the upper layer to ensure that the sealing strip 2 of the upper layer can be stably put into the mold. While waiting for the next time the sealing strip 2 of the lower layer is put into the mold, the drive component drives the two groups of second support plates 17 to rotate in the opposite direction and reset.

[0046] The mold insertion operation of the sealing strip on the traditional sealing strip welding machine generally adopts manual or mechanical arm grasping to assist the mold insertion, but due to the soft nature of the sealing strip, the sealing strip near the mold entry of the welding machine is prone to sag under the action of gravity, thereby affecting the effect and efficiency of the sealing strip entering the mold. In this embodiment of the utility model, a driving component is used to drive the two groups of second support plates 17 to rotate synchronously to form a support plane higher than the top of the two groups of first support plates 9, which can achieve reliable support for the mold entry sections of the upper and lower layers of the sealing strip 2, thereby preventing the sealing strip 2 from sagging, and effectively improving the mold entry effect and efficiency of the upper and lower layers of the sealing strip 2.

The support rods 15 can be given way between the two groups of vertical sections 7 to ensure the stability and reliability of the rotation of the support rods 15.

[0054] In this embodiment of the present invention, if Figure 3 and Figure 4 As shown, the base 3 may include a groove.
