[0026] See Figures 1 to 4 , a welding device according to an embodiment of the present invention includes: a workbench 100, on which a first station 110, a welding station 120, and a second station 130 are arranged at intervals along the workpiece conveying direction. At the welding station 120, a clamping device 200 and a welding device 300 located above the clamping device 200 are provided. On the workbench 100, a lifting and conveying mechanism 400 is provided below the clamping device 200. The lifting and conveying mechanism 400 includes a linear reciprocating assembly 410 extending along the workpiece conveying direction, a lifting assembly 420 connected to the linear reciprocating assembly 410, and a supporting plate 430 connected to the lifting assembly 420. On the supporting plate 430, a positioning clamping plate assembly 440 is provided that can push the workpiece on the first station 110 to the welding station 120.

[0027] The first station 110 of the welding device with the above structure receives the workpiece from the previous process. The positioning clamping plate assembly 440 of the lifting and conveying mechanism 400 clamps the workpiece, and then the lifting assembly 420 drives the positioning clamping plate assembly 440 to descend. The linear reciprocating assembly 410 moves the workpiece to below the welding station 120, and then the lifting assembly 420 drives the positioning clamping plate assembly 440 to ascend. Then the clamping device 200 clamps and positions the workpiece, and the welding device 300 performs ultrasonic welding; the welding device accurately transports and positions the workpiece, thereby ensuring the quality of the product after welding operations and improving the qualified product rate. Among them, it should be noted that for the assembly of the air filter element, the workpiece to be welded is the box body with a ring end cover placed on it.

[0028] See Figure 1 and Figure 3, in some embodiments of the present invention, a second station 130 is provided on the workbench 100 behind the welding station 120. A second conveyor belt 500 corresponding to the second station 130 is provided on the workbench 100. A first push plate 450 capable of pushing the workpiece on the welding station 120 to the second station 130 and a second push plate 460 capable of pushing the workpiece on the second station 130 to the second conveyor belt 500 are provided on the supporting plate 430. Through the above structure, automatic transmission between the first station 110, the welding station 120, and the second station 130 can be realized without manual participation, improving production automation. It can be understood that the first station 110 places the workpiece to be welded, and the second station 130 places the welded workpiece for the next process. When the positioning clamping plate assembly 440 moves the workpiece to be welded at the first station 110 to the welding station 120, the first push plate 450 also moves the welded workpiece at the welding station 120 to the second station 130 at the same time, and the second push plate 460 moves the workpiece on the second station 130 to the second conveyor belt 500 at the same time, greatly improving the transmission efficiency.

[0029] See Figure 3 , in some embodiments of the present invention, in order to turn the welded workpiece and convey it to the next process, the extending direction of the second conveyor belt 500 is orthogonal to the workpiece conveying direction. A guiding inclined plate 510 capable of guiding the workpiece to the side of the second conveyor belt 500 is provided on the workbench 100. The guiding inclined plate 510 helps to smoothly guide the workpiece onto the second conveyor belt 500.

[0030] See Figure 1 , in some embodiments of the present invention, in order to prevent the molten plastic from adhering to the welding head during welding and affecting the welding effect, a brush assembly 600 is movably provided on the workbench 100 and can extend below the welding device 300 to wipe the welding head.

[0031] See Figure 1 , in some embodiments of the present invention, the brush assembly 600 includes a first linear driver 610 and a brush member 620 detachably connected to the output end of the first linear driver 610. The output end of the first linear driver 610 moves horizontally in a telescopic manner. Since the brush member 620 is a consumable and needs to be replaced regularly, the brush member 620 is detachably connected to the output end of the first linear driver 610 for convenient replacement of the brush member 620.

[0032] See Figure 2 , in some embodiments of the present invention, a first conveyor belt 700 opposite to the first station 110 is provided on the workbench 100. A transfer device 800 capable of transferring the workpiece on the first conveyor belt 700 to the first station 110 is provided on the workbench 100.

[0033] See also Figure 2 In some embodiments of the present invention, the transfer device 800 includes a sliding seat 810 whose sliding direction is parallel to the first conveyor belt 700, and the sliding seat 810 is provided with a connecting seat 820 that can move up and down relative to the sliding seat 810, and the connecting seat 820 is provided with a clamping assembly 830, and the workbench 100 is provided with a driving mechanism 840 that can synchronously drive the connecting seat 820 to move up and down relative to the sliding seat 810 and drive the sliding seat 810 to slide back and forth toward the first workstation 110.

[0034] See also Figure 2 In some embodiments of the present invention, the driving mechanism 840 includes a motor 841 disposed on the workbench 100, the output end of the motor 841 is connected to one end of a crank 842, and the other end of the crank 842 is pivotally connected to the connecting seat 820. It can be understood that when the motor 841 drives the crank 842 to rotate, it can drive the connecting seat 820 to move up and down on the sliding seat 810. At the same time, the sliding seat 810 is subjected to the force of the connecting seat 820 and slides back and forth to approach or move away from the first station 110. The transfer device 800 with the above structure is used to transfer the workpiece with high conveying accuracy, and only one motor 841 is needed as the driving source, the structure is ingenious, and the cost is low.

[0035] See also Figure 3 In some embodiments of the present invention, a first long strip 101 and a second long strip 102 are arranged parallel to each other on the workbench 100 at intervals, and a make way groove for the lifting and lowering movement of the positioning clamping plate assembly 440 is defined between the first long strip 101 and the second long strip 102. The clamping device 200 includes a first clamping block 210 slidably arranged on the first long strip 101 and a second clamping block 220 movably arranged on the second long strip 102. The first clamping block 210 and the second clamping block 220 are respectively connected to a second linear drive 230 that drives the two to approach each other. The first clamping block 210 and the second clamping block 220 are respectively provided with a first positioning groove and a second positioning groove. The second linear drive 230 drives the first positioning groove and the second positioning groove to approach each other to form a clamping cavity. It can be understood that in order to ensure the accuracy of the welding position, before the welding device 300 intervenes in the work, the two second linear drives 230 drive the first clamping block 210 and the second clamping block 220 to approach each other to clamp the workpiece, and the clamping cavity composed of the first positioning groove and the second positioning groove prevents the workpiece from moving relative to the clamping device 200.

[0036] See also Figure 3, in some embodiments of the present invention, a first guiding strip 103 is provided at one end of the first long strip 101 adjacent to the first working station 110, and a second guiding strip 104 is provided at one end of the second long strip 102 adjacent to the first working station 110. A guiding channel is defined between the first guiding strip 103 and the second guiding strip 104. Both the first guiding strip 103 and the second guiding strip 104 are provided with oblong holes 105 extending along their width directions. The first guiding strip 103 and the second guiding strip 104 are both connected to the first long strip 101 or the second long strip 102 by threaded fasteners passing through the corresponding oblong holes 105. The guiding channel is used to guide the workpiece to move between the first working station 110, the welding working station 120 and the second working station 130, and the width of the guiding channel can be adjusted by the above structure, so as to adapt to workpieces of different sizes.

[0037] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
