[0002] The washing machine controller is also called the washing machine control circuit touch button panel, which is used to control the operation of the washing machine. During the production process, the upper and lower panel shell components are ultrasonically welded together by an intelligent welding robot using ultrasonic technology.

[0003] The intelligent welding robot used for welding washing machine controllers in the prior art mainly comprises a reprogrammable intelligent industrial robot. An ultrasonic welding assembly for welding the upper and lower panel shells is installed at the end of the mechanical arm of the industrial robot. When in use, the lower panel shell opening is placed upward in a placement groove opened on the upper surface of the welding seat, the upper panel shell opening is placed downward to fit with the opening of the lower panel shell, and the concave welding head is pressed against the outer ring of the upper panel shell. The welding head emits ultrasonic ultra-high frequency vibration. Under pressure, the surfaces of the two objects are rubbed against each other to form a fusion between the molecular layers, thereby welding the upper and lower panel shells.

[0004] However, there are still corresponding disadvantages in actual use: when the intelligent welding robot in the prior art is in use, it is not convenient to clean the dust attached to the fitting surfaces of the upper panel shell and the lower panel shell. The dust can easily reduce the effect of ultrasonic welding, easily cause pores, and produce welding defects. Before each welding, the dust on the fitting surfaces of the upper panel shell and the lower panel shell needs to be wiped and cleaned manually, which reduces the efficiency of welding and the practicability of the equipment is low.

[0023] Beneficial Effects

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention adopts the coordinated design of structures such as an intelligent robot body, an ultrasonic welding head, a placement shell, a workbench, and a dust cleaning mechanism. The intelligent robot body drives the ultrasonic welding head to move downward. During the downward movement of the ultrasonic welding head, the mounting plate is driven downward by the connecting plate and the first spring telescopic rod. The sliding shell is driven by the driving mechanism to move from the left side of the bottom surface of the mounting plate to the right side of the bottom surface of the mounting plate. During the movement of the sliding shell from left to right, the upper dust sticking roller is driven to move to clean the dust on the opening fitting surface of the upper panel shell through the action of the guide mechanism. At the same time, when the sliding shell moves, the lower dust sticking roller is driven to move to clean the dust on the opening fitting surface of the lower panel shell through the connecting column and the connecting shell. The dust can be adhered to the surface of the dust sticking roller, which is convenient for automatically cleaning the dust attached to the fitting surfaces of the upper and lower panel shells before welding, avoiding the air hole phenomenon caused by dust problems during welding, and improving the welding effect and the practicability of the equipment.

[0026] 2. The present invention adopts the coordinated design of the lower dust-sticking roller, the sliding shell, the connecting column, the connecting shell, the cooling mechanism and the like. When the sliding shell moves from left to right, the connecting column and the connecting shell drive the lower dust-sticking roller to move to clean the dust on the open fitting surface of the lower panel shell. The lower dust-sticking roller rotates under the interaction with the open fitting surface of the lower panel shell. When the lower dust-sticking roller rotates, it can drive the cooling mechanism to operate and inhale and compress the external air. When the upper and lower panel shells are welded, the ultrasonic welding head moves upward to drive the sliding shell to move upward, and the driving mechanism can drive the sliding shell to move upward while moving from right to left. When the sliding shell moves from right to left, the connecting column and the connecting shell drive the lower dust-sticking roller to move and contact the top surface of the welded panel shell. At the same time, the cooling mechanism can spray the inhaled compressed air to the surface of the panel shell, so as to cool down the welded panel shell, thereby improving the cooling efficiency. This solves the problem that the natural cooling of the panel shell after welding in the prior art takes a long time, has low cooling efficiency and reduces the production efficiency of the washing machine controller.

[0042] The dust cleaning mechanism 4 includes a connecting plate 41 fixedly sleeved on the upper part of the outer surface of the ultrasonic welding head 3, a mounting plate 42 slidably sleeved on the middle part of the outer surface of the ultrasonic welding head 3, a sliding shell 43 that moves laterally at the rear part of the bottom surface of the mounting plate 42, a connecting column 44 that moves up and down in the inner cavity of the sliding shell 43, a connecting shell 45 fixedly mounted on the bottom surface of the connecting column 44, a lower dust-sticking roller 46 that is movably mounted on the front side wall of the connecting shell 45 through a bearing for cleaning the dust on the opening fitting surface of the lower panel shell, an upper dust-sticking roller 47 for cleaning the dust on the opening fitting surface of the upper panel shell is provided at the front part of the sliding shell 43, a guiding mechanism 6 for limiting the movement trajectory of the upper dust-sticking roller 47 is provided on the bottom surface of the mounting plate 42 and the front side wall of the sliding shell 43, a driving mechanism 7 for driving the sliding shell 43 to move laterally is provided at the rear part of the mounting plate 42, and a cooling mechanism 8 for cooling the upper and lower panel shells after welding is provided in the inner cavity of the lower dust-sticking roller 46;

[0043] Among them, the bottom surface of the connecting plate 41 and the upper surface of the mounting plate 42 are connected by two symmetrically arranged first spring telescopic rods 9, and a second spring telescopic rod 10 is vertically arranged at the rear of the sliding shell 43 and the connecting shell 45, and the upper and lower ends of the second spring telescopic rod 10 are respectively fixedly connected to the rear side wall of the sliding shell 43 and the rear side wall of the connecting shell 45.

[0044] When in use, first place the opening of the upper panel shell downward in the groove on the bottom surface of the ultrasonic welding head 3, and at the same time place the opening of the lower panel shell upward in the placement shell 5, start the intelligent robot body 2 to drive the ultrasonic welding head 3 to move downward, and during the downward movement of the ultrasonic welding head 3, the mounting plate 42 is driven to move downward by the connecting plate 41 and the first spring telescopic rod 9, and the sliding shell 43 is driven by the action of the driving mechanism 7 to move from the left side of the bottom surface of the mounting plate 42 to the right side of the bottom surface of the mounting plate 42. During the movement of the sliding shell 43 from left to right, the upper dust-sticking roller 47 is driven by the action of the guide mechanism 6 to move to clean the dust on the opening fitting surface of the upper panel shell. At the same time, when the sliding shell 43 moves, the lower dust-sticking roller 46 is driven by the connecting column 44 and the connecting shell 45 to move to clean the dust on the opening fitting surface of the lower panel shell, which can stick the dust to the surface of the dust-sticking roller, so that the dust attached to the fitting surfaces of the upper and lower panel shells can be automatically cleaned before welding, thereby avoiding the air hole phenomenon caused by dust problems during welding, thereby improving the welding effect and the practicality of the equipment.

[0045] It should be noted that when the sliding shell 43 moves from left to right, the lower dust-sticking roller 46 is driven by the connecting column 44 and the connecting shell 45 to move to clean the dust on the open fitting surface of the lower panel shell, the lower dust-sticking roller 46 rotates under the interaction with the open fitting surface of the lower panel shell. When the lower dust-sticking roller 46 rotates, it can drive the cooling mechanism 8 to operate and inhale and compress the external air. When the upper and lower panel shells are welded, the ultrasonic welding head 3 moves upward to drive the sliding shell 43 to move upward, and the driving mechanism 7 can drive the sliding shell 43 to move upward while moving from right to left. When the sliding shell 43 moves from right to left, the lower dust-sticking roller 46 is driven by the connecting column 44 and the connecting shell 45 to move and contact the top surface of the welded panel shell. At the same time, the cooling mechanism 8 can spray the inhaled compressed air to the surface of the panel shell, and the welded panel shell is cooled by air, which improves the cooling efficiency and avoids the problem of long time and low cooling efficiency of natural cooling after welding of the traditional panel shell, which reduces the production efficiency of the washing machine controller.

[0046] like Figure 5 As shown, the driving mechanism 7 includes a mounting channel opened at the rear of the bottom surface of the mounting plate 42, a driving screw 71 movably mounted in the inner cavity of the mounting channel through a bearing for driving the sliding housing 43 to move, pulleys 72 symmetrically fixedly sleeved on the left and right sides of the driving screw 71, and slide rails 73 symmetrically and vertically fixedly mounted on the left and right sides of the upper surface of the workbench 1;

[0047] The outer surface of the sliding shell 43 is slidably connected to the inner cavity of the installation channel, the top of the slide rail 73 passes through the inner cavity of the installation channel, and the outer ring of the pulley 72 is movably connected to the rear side wall of the slide rail 73.

[0048] When in use, the ultrasonic welding head 3 moves up and down, and the mounting plate 42 can be driven to move up and down through the connecting plate 41 and the first spring telescopic rod 9. When the mounting plate 42 moves, the driving screw 71 can be rotated under the action of the pulley 72 and the slide rail 73, so that when the driving screw 71 rotates, the sliding shell 43 can be driven to move laterally.

[0049] like Figure 3 , Figure 4 and Figure 6 As shown, the guide mechanism 6 includes a slide groove vertically opened on the front side wall of the slide housing 43, a slider 61 moving up and down in the inner cavity of the slide groove, a compression spring 62 vertically arranged on the bottom surface of the slider 61 and the bottom surface of the inner cavity of the slide groove, a guide wheel 63 fixedly sleeved on the shaft of the rear side wall of the upper dust sticking roller 47, and a guide rail 64 fixedly installed on the bottom surface of the mounting plate 42;

[0050] Among them, the upper and lower ends of the compression spring 62 are fixedly connected to the bottom surface of the slider 61 and the bottom surface of the inner cavity of the slide groove respectively, the rear side wall connecting shaft of the upper dust-sticking roller 47 is movably connected to the front side wall of the slider 61 through a bearing, and the outer ring of the guide wheel 63 is movably connected to the bottom surface of the guide rail 64.

[0051] When in use, the sliding shell 43 moves laterally, driving the slider 61 to move. Driven by the upward elastic force of the compression spring 62, the slider 61 moves and drives the guide wheel 63 to fit the bottom surface of the guide rail 64. When the guide wheel 63 drives the upper dust-sticking roller 47 to move from left to right along the middle of the bottom surface of the guide rail 64, the upper dust-sticking roller 47 can clean the dust on the opening fitting surface of the upper panel shell. When the guide wheel 63 drives the upper dust-sticking roller 47 to move along the bottom surface of the guide rail 64 to the rightmost position, it can avoid affecting the downward movement of the ultrasonic welding head 3 and driving the upper panel shell to contact and fit with the lower panel shell.

[0052] like Figure 8 , Fig.11 and Fig.12 As shown, the cooling mechanism 8 includes an air storage tank 81 arranged in the inner cavity of the lower dust sticking roller 46, an air delivery mechanism 11 arranged at the front side of the air storage tank 81 for delivering air to the inner cavity of the air storage tank 81, a ventilation groove 82 provided at the bottom of the outer surface of the air storage tank 81, an exhaust channel 83 provided at the bottom surface of the inner cavity of the air storage tank 81 for communicating with the inner cavity of the ventilation groove 82, a sealing block 84 moving back and forth on the bottom surface of the inner cavity of the air storage tank 81 for sealing the inner cavity of the exhaust channel 83, an air injection hole 85 equidistantly provided on the outer surface of the lower dust sticking roller 46 in the circumferential direction, a linkage mechanism 12 provided in the inner cavity of the air storage tank 81, the inner cavity of the connecting column 44 and the inner cavity of the sliding shell 43 for driving the sealing block 84 to move forward and backward, and a transmission mechanism 13 provided in the inner cavity of the connecting shell 45 for assisting the lower dust sticking roller 46 to rotate;

[0053] Among them, the lower part of the outer surface of the air storage tank 81 is in contact with the bottom surface of the inner cavity of the lower dust-sticking roller 46, and a connecting rod 86 is fixedly installed at the center of the rear side wall of the air storage tank 81. The connecting rod 86 penetrates the connecting shaft of the rear side wall of the lower dust-sticking roller 46 and is fixedly connected to the rear part of the inner cavity of the connecting shell 45.

[0054] When in use, when the sliding shell 43 moves from left to right through the connecting column 44 and the connecting shell 45 to drive the lower dust sticking roller 46 to move to clean the dust on the open fitting surface of the lower panel shell, the lower dust sticking roller 46 rotates under the interaction with the open fitting surface of the lower panel shell. Under the action of the transmission mechanism 13 and the upper surface of the workbench 1, the lower dust sticking roller 46 can be assisted to rotate stably. When the lower dust sticking roller 46 rotates, it can drive the air delivery mechanism 11 to deliver external air to the inner cavity of the air storage tank 81. When the ultrasonic welding head 3 moves downward, the driving mechanism 7 drives the sliding shell 43 to move from left to right, and also drives the sliding shell 43 to move downward. When the sliding shell 43 moves downward, the connecting column 44 and the connecting shell 45 drive the lower dust sticking roller 46 to move from left to right. The driving mechanism 12 drives the sealing block 84 to move and close the inner cavity of the exhaust channel 83 to prevent the air stored in the gas tank 81 from leaking. When the welding is completed, the ultrasonic welding head 3 moves upward and drives the sliding shell 43 from right to left through the driving mechanism 7, and also drives the sliding shell 43 to move upward. When the sliding shell 43 moves from right to left, it drives the lower dust-sticking roller 46 to move and contact the top surface of the welded panel shell. At the same time, when the sliding shell 43 moves upward, the linkage mechanism 12 drives the sealing block 84 to move and separate from the inner cavity of the exhaust channel 83, so that the compressed air in the gas tank 81 can be sprayed to the surface of the panel shell through the jet hole 85, so as to cool the welded panel shell.

[0055] like Figure 8 As shown, the transmission mechanism 13 includes a roller 131 movably mounted on the lower part of the inner cavity of the connecting shell 45 through a bearing, a main gear 132 fixedly mounted on the front connecting shaft of the roller 131, and a slave gear 133 fixedly mounted on the rear connecting shaft of the lower dust-sticking roller 46; wherein the main gear 132 is meshed with the slave gear 133; wherein the outer ring bottom of the roller 131 is movably connected to the upper surface of the workbench 1.

[0056] When in use, the sliding shell 43 moves from left to right through the connecting column 44 and the connecting shell 45 to drive the roller 131 to move. The roller 131 can rotate under the interaction with the upper surface of the workbench 1. When the roller 131 rotates, the lower dust-sticking roller 46 can be driven to rotate through the main gear 132 and the slave gear 133.

[0057] like Figure 8 As shown, the gas delivery mechanism 11 includes an air cavity 111 opened at the front side of the gas storage tank 81, an air inlet 112 opened at the rear part of the top surface of the inner cavity of the air cavity 111, an air outlet 113 opened at the rear part of the inner cavity of the air cavity 111 and connected with the inner cavity of the gas storage tank 81, a compression block 114 sliding back and forth in the inner cavity of the air cavity 111, and a reciprocating screw 115 fixedly installed at the front part of the inner cavity of the lower dust sticking roller 46 and penetrating into the air cavity 111 for driving the compression block 114 to move;

[0058] The inner cavity of the air inlet hole 112 is provided with a one-way air inlet valve for introducing external air into the air cavity 111 , and the inner cavity of the air outlet hole 113 is provided with a one-way air outlet valve for introducing the air in the air cavity 111 into the air storage tank 81 .

[0059] When in use, the lower dust-sticking roller 46 rotates to drive the reciprocating screw 115 to rotate, and the reciprocating screw 115 rotates to drive the compression block 114 to move back and forth. Through the air inlet 112, the air cavity 111 and the air outlet 113, the compression block 114 can transport external air to the inner cavity of the air storage tank 81 for storage when it moves back and forth.

[0060] like Fig. 9 and Fig.10 As shown, the linkage mechanism 12 includes a slide bar 121 that moves up and down in the inner cavity of the connecting column 44, a pin housing 122 fixedly mounted on the top of the slide bar 121, two paddles 123 symmetrically hinged on the front and rear sides of the upper inner cavity of the connecting column 44, two pin shafts 124 symmetrically fixedly mounted on the opposite sides of the two paddles 123, two clamping plates 125 symmetrically fixedly mounted on the front and rear sides of the inner cavity of the slide housing 43, and a connecting piece 14 arranged at the bottom end of the slide bar 121 for connecting the sealing block 84;

[0061] The outer surface of the pin shaft 124 is movably connected to the inner cavity of the pin housing 122 , and the outer side of the paddle 123 is movably connected to the convex teeth arranged on the surface of the clamping plate 125 .

[0062] When in use, when the ultrasonic welding head 3 drives the sliding shell 43 to move downward, the sliding shell 43 drives the two card plates 125 to move downward, and the card plates 125 interact with the paddles 123, so that the relative surfaces of the two paddles 123 can be flipped upward, so that the paddles 123 drive the pin shaft 124 to drive the pin shell 122 to move upward, and the pin shell 122 drives the sliding rod 121 to move upward. When the sliding rod 121 moves upward, the sealing block 84 is driven by the connecting piece 14 to close the inner cavity of the exhaust channel 83 to prevent the air in the gas storage tank 81 from leaking. When the ultrasonic welding head 3 drives the sliding shell 43 to move upward, the sliding shell 43 drives the card plates 125 to move upward, so that the relative surfaces of the two paddles 123 can be flipped downward, so that the sliding rod 121 can be driven downward by the pin shaft 124 and the pin shell 122. When the sliding rod 121 moves downward, the sealing block 84 is driven by the connecting piece 14 to separate from the inner cavity of the exhaust channel 83, so that the air in the gas storage tank 81 can be sprayed out to cool the panel shell after welding.

[0063] like Figure 8 As shown, the connecting member 14 includes a connecting rod 141 fixedly mounted on the rear side wall of the sealing block 84, the rear end of the connecting rod 141 extends into the inner cavity of the connecting rod 86, a limiting hole is provided at the rear portion of the top surface of the inner cavity of the connecting rod 86, and a rotating rod 142 is hinged at the rear portion of the connecting rod 141, and the top of the rotating rod 142 is hinged to the bottom of the sliding rod 121.

[0064] When in use, when the sliding rod 121 moves up and down, the rotating rod 142 can drive the connecting rod 141 to move forward and backward. When the connecting rod 141 moves backward, it can drive the sealing block 84 to close the inner cavity of the exhaust channel 83. When the connecting rod 141 moves forward, it can drive the sealing block 84 to separate from the inner cavity of the exhaust channel 83.

[0065] The working principle and use process of the present invention:

[0066] When in use, first place the upper panel shell opening downward into the groove on the bottom surface of the ultrasonic welding head 3, and at the same time place the lower panel shell opening upward into the placement shell 5, start the intelligent robot body 2 to drive the ultrasonic welding head 3 to move downward, and during the downward movement of the ultrasonic welding head 3, the mounting plate 42 is driven to move downward through the connecting plate 41 and the first spring telescopic rod 9. When the mounting plate 42 moves downward, the driving screw 71 can be rotated under the action of the pulley 72 and the slide rail 73, so that when the driving screw 71 rotates, it can drive the sliding shell 43 to move from the left side of the bottom surface of the mounting plate 42 to the left side. On the right side of the bottom surface of the mounting plate 42, when the sliding shell 43 moves, it drives the slider 61 to move. Driven by the upward elastic force of the compression spring 62, the slider 61 moves and drives the guide wheel 63 to move in contact with the bottom surface of the guide rail 64. When the guide wheel 63 drives the upper dust-sticking roller 47 to move from left to right along the middle of the bottom surface of the guide rail 64, the upper dust-sticking roller 47 can clean the dust on the opening contact surface of the upper panel shell. At the same time, when the sliding shell 43 moves, the lower dust-sticking roller 46 is driven by the connecting column 44 and the connecting shell 45 to move to clean the dust on the opening contact surface of the lower panel shell, so that the dust can be adhered to the surface of the dust-sticking roller, and the lower dust-sticking roller 46 can be cleaned. When the roller 46 moves to clean the dust on the open fitting surface of the lower panel shell, the lower dust-sticking roller 46 rotates under the interaction with the open fitting surface of the lower panel shell, and the roller 131 can rotate under the interaction with the upper surface of the workbench 1, so that when the roller 131 rotates, the main gear 132 and the slave gear 133 can assist the lower dust-sticking roller 46 to rotate stably, and at the same time, the lower dust-sticking roller 46 rotates to drive the reciprocating screw rod 115 to rotate, and the reciprocating screw rod 115 rotates to drive the compression block 114 to reciprocate, and the compression block 114 moves back and forth through the air inlet 112, the air cavity 111 and the air outlet 113. When the sliding shell 43 moves backward, the external air can be transported to the inner cavity of the gas storage tank 81 for storage. At the same time, when the ultrasonic welding head 3 drives the sliding shell 43 to move downward, the sliding shell 43 drives the two clamping plates 125 to move downward. The clamping plates 125 interact with the paddles 123 to make the relative surfaces of the two paddles 123 flip upward, so that the paddles 123 drive the pin shaft 124 to drive the pin shell 122 to move upward, and the pin shell 122 drives the sliding rod 121 to move upward. When the sliding rod 121 moves upward, the sealing block 84 is driven by the connecting member 14 to close the inner cavity of the exhaust channel 83 to prevent the air in the gas storage tank 81 from leaking out.

[0067] When the upper and lower panel shells are welded, the ultrasonic welding head 3 moves upward and drives the sliding shell 43 from right to left through the driving mechanism 7, while also driving the sliding shell 43 to move upward. When the sliding shell 43 moves from right to left, it drives the lower dust-sticking roller 46 to move and contact the top surface of the welded panel shell. At the same time, when the sliding shell 43 moves upward, the sliding shell 43 drives the card plate 125 to move upward, so that the relative surfaces of the two paddles 123 can be flipped downward, so that the sliding rod 121 can be driven to move downward through the pin shaft 124 and the pin shell 122. When the sliding rod 121 moves downward, the sealing block 84 is driven to separate from the inner cavity of the exhaust channel 83 through the connecting piece 14, so that the compressed air in the air storage tank 81 is ejected to the surface of the panel shell through the jet hole 85, so as to cool the welded panel shell.
