[0069] The present application provides a welding device.

[0070] Please refer to Figure 1 and Figure 2The welding device 100 comprises a rack 110, a supporting member 112, a welding assembly 120 and a control device 113. Specifically, the rack 110 has a travel passage 111 extending through in a first horizontal direction D1. The supporting member 112 extends to the travel passage 111, and is used for carrying a workpiece to be welded. The welding assembly 120 is movably connected to the rack 110 between a first position and a second position in the first horizontal direction D1. The welding assembly 120 comprises a pressing member 121 movably connected to the rack 110 between a pressing position and a releasing position. The pressing member 121 in the pressing position abuts against the workpiece to be welded, and the pressing member 121 in the releasing position is separated from the workpiece to be welded. The control device 113 is connected to the welding assembly 120 to control the operation of the welding assembly 120. It is to be noted that, during the movement of the workpiece to be welded in the first horizontal direction D1, the pressing member 121 in the pressing position can press the workpiece to be welded, so that the welding assembly 120 can move synchronously with the workpiece to be welded in the first horizontal direction D1 under the action of friction.

[0071] According to the welding device 100 of the utility model, the pressing member 121 in the pressing position abuts against the workpiece to be welded, so that the welding assembly 120 can move synchronously with the workpiece to be welded, and the workpiece to be welded will not be dislocated during the welding process, thereby ensuring the product quality.

[0072] Further, in the state that the pressing member 121 is in the pressing position, the welding assembly 120 can move with the workpiece to be welded in the first horizontal direction D1 from the first position to the second position (see the arrow in Figure 1 Further, in the state that the pressing member 121 is in the pressing position, the welding assembly 120 can move with the workpiece to be welded in the first horizontal direction D1 from the first position to the second position (see the arrow in Figure 2 The welding device 100 further comprises a first elastic member 114, which drives the welding assembly 120 to move from the second position to the first position in the state that the pressing member 121 is away from the pressing position. Specifically, Figure 2 Further, the first elastic member 114 can be arranged in pairs, and adjacent first elastic members 114 are spaced apart in the vertical direction DH. The two ends of the first elastic member 114 are respectively connected to the rack 110 and the welding assembly 120.

[0073] Figure 1 Further, the rack 110 can be configured as a portal frame in a substantially door frame shape, and the portal frame has the travel passage 111 for the workpiece to be welded to pass through. During the movement of the workpiece to be welded in the first horizontal direction D1 and finally passing through the travel passage 111, the pressing member 121 in the pressing position is in close contact with the workpiece to be welded, so that the welding assembly 120 moves with the workpiece to be welded, and the workpiece to be welded will not be dislocated during the movement and welding process, thereby ensuring the product quality.

[0074] Please continue to refer to Figure 1 and Figure 2 The welding device 100 further comprises a first mounting member 115 connected to the frame 110. The welding assembly 120 further comprises a driving member 122 and a spot welding member 123. Specifically, the driving member 122 is movably connected to the first mounting member 115 along the first horizontal direction D1 between a first position and a second position, and the pressing member 121 is connected to the driving member 122. The spot welding member 123 is located inside the pressing member 121. It should be noted that in the state that the pressing member 121 is located at the pressing position, the spot welding member 123 can move synchronously with the workpiece along the first horizontal direction D1. Further, the driving member 122 comprises a telescopic portion 122a and a main body portion 122b connected to each other. The pressing member 121 is connected to the telescopic portion 122a, and the telescopic portion 122a is used to drive the pressing member 121 to move along the vertical direction DH. Preferably, the driving member 122 can be configured as a slide cylinder, and the main body portion 122b is connected to the first elastic member 114 on the side away from the telescopic portion 122a along the first horizontal direction D1. The welding assembly 120 further comprises a second elastic member 124 located between the telescopic portion 122a and the pressing member 121 and connected to the telescopic portion 122a and the pressing member 121.

[0075] Specifically, the pressing member 121 comprises a connecting portion 121a and a contact portion 121b connected to each other, and the pressing member 121 has a through hole penetrating through the connecting portion 121a and the contact portion 121b along the vertical direction DH. The connecting portion 121a is located above the contact portion 121b and abuts against the second elastic member 124. It should be noted that the contact portion 121b is used to contact the workpiece, and the contact portion 121b protrudes outwardly along the radial direction of itself from the connecting portion 121a to increase the contact area of the workpiece. In actual use, when it is necessary to weld the workpiece, the telescopic portion 122a drives the pressing member 121 to move along the vertical direction DH from the release position to the pressing position. After the contact portion 121b abuts against the workpiece, the telescopic portion 122a continues to move downward to compress the second elastic member 124, so that the spot welding member 123 penetrates through the through hole along the vertical direction DH and finally abuts against the workpiece to complete spot welding. In this process, the pressing member 121 presses the workpiece by means of the elastic force of the second elastic member 124, so that the spot welding member 123 can move along the first horizontal direction D1 with the workpiece, ensuring that the workpiece will not be dislocated. After the welding is completed, the telescopic portion 122a moves upward, so that the pressing member 121 moves from the pressing position to the release position. After the pressing member 121 leaves the workpiece, the welding assembly 120 moves from the second position to the first position under the action of the first elastic member 114 and is finally maintained at the first position.

[0076] Please continue to refer to Figure 1 and Figure 2, in order to improve the activity freedom of the welding assembly 120 to adapt to the spot welding requirements of the workpieces at different points, the first mounting member 115 can be configured to be adjustably connected to the rack 110 along a second horizontal direction D2 perpendicular to the first horizontal direction D1. Specifically, the welding device 100 further comprises a second mounting member 116 and a first guide assembly 117. The second mounting member 116 is connected to the rack 110. The first guide assembly 117 is located between the first mounting member 115 and the second mounting member 116, and the first guide assembly 117 is connected to the first mounting member 115 and the second mounting member 116. Thus, the position of the first mounting member 115 along the second horizontal direction D2 relative to the second mounting member 116 (or the rack 110) is adjusted to adapt to the welding requirements of different workpieces. For example, the first guide assembly 117 comprises a first sliding rail 117a and a first sliding block 117b. The first sliding rail 117a is arranged along the second horizontal direction D2, and the first sliding block 117b is adjustably connected to the first sliding rail 117a along the second horizontal direction D2. One of the first sliding rail 117a and the first sliding block 117b is connected to the first mounting member 115, and the other of the first sliding rail 117a and the first sliding block 117b is connected to the second mounting member 116. For example, the first sliding rail 117a is connected to the second mounting member 116, and the first sliding block 117b is connected to the first mounting member 115. Alternatively, an adapter bracket is additionally arranged between the first mounting member 115 and the first sliding block 117b, and the adapter bracket is connected to the first sliding block 117b and the first mounting member 115. It is easily conceivable that, since the workpieces are moved along the first horizontal direction D1, the position of the welding assembly 120 relative to the second horizontal direction D2 needs to be fixed during the process that the welding assembly 120 moves synchronously with the workpieces along the first horizontal direction D1, therefore, the first guide assembly 117 further comprises a positioning member, which limits the movement of the first sliding block 117b relative to the first sliding rail 117a along the second horizontal direction D2 after the position of the welding assembly 120 relative to the rack 110 along the second horizontal direction D2 is adjusted, so as to ensure that the welding assembly 120 will not move along the second horizontal direction D2. It can be understood that, in order to facilitate the movement of the welding assembly 120 relative to the first mounting member 115 along the first horizontal direction D1, the welding device 100 further comprises a second guide assembly 119, which is located between the welding assembly 120 and the first mounting member 115, and the second guide assembly 119 is connected to the first mounting member 115 and the welding assembly 120. The second guide assembly 119 can comprise a second sliding rail 119a and a second sliding block 119b which are adapted to each other, the second sliding rail 119a is connected to one of the first mounting member 115 and the welding assembly 120, and the second sliding block 119b is connected to the other of the first mounting member 115 and the welding assembly 120. For example, the second sliding rail 119a is connected to the first mounting member 115, and the second sliding block 119b is connected to the welding assembly 120.

[0077] Please continue to refer to Figure 2 On the basis of the foregoing, in order to ensure different spot welding position requirements, the welding device 100 further comprises a third mounting member 118 connected to the first mounting member 115. Further, the third mounting member 118 is connected with the aforementioned welding assembly 120. The third mounting member 118 is adjustably connected to the first mounting member 115 along the second horizontal direction D2, and / or the welding assembly 120 connected with the aforementioned third mounting member 118 is configured to be adjustably connected to the third mounting member 118 along the second horizontal direction D2. Preferably, the aforementioned first guide assembly 117 is arranged between the welding assembly 120 and the third mounting member 118.

[0078] According to the welding device of the present application, the welding assembly can perform spot welding on the workpiece to be welded (e.g. multi-layer thermoplastic material) to achieve pre-fixing, and in this process, the welding assembly can move synchronously with the workpiece to be welded along the first horizontal direction, and the position of the spot welding member relative to the workpiece to be welded along the first horizontal direction will not change or be misaligned due to the movement of the workpiece to be welded, thereby ensuring the efficiency of the assembly line production and improving the yield of the product.
