[0032] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily.

[0033] It is usually necessary to install a sponge on the air conditioner outer shell. The sponge can absorb the vibration and noise generated when the air conditioner is running, so as to reduce the impact on the external environment and make the air conditioner run more quietly. At the same time, it protects the parts inside the air conditioner and prolongs the service life. The commonly used sponge component is a sponge with an adhesive layer on the back, and the surface of the adhesive layer is covered with an adhesive film. Before sticking the sponge on the air conditioner outer shell, the adhesive film on the back of the sponge needs to be torn off to expose the adhesive layer.

[0034] In the prior art, the sponge is attached to the outer shell of the traditional air conditioner manually. Since the sponge needs to be separated, the adhesive film needs to be torn off, and the sponge needs to be attached manually, the manual operation will lead to low production efficiency and high labor costs.

[0035] Thus, the conventional air conditioner outer shell has the problems of low production efficiency and high labor cost in the sponge pasting process.

[0036] Based on this, an exemplary embodiment of the present application provides an automatic sponge sticking device for an air-conditioning outdoor unit casing, the device comprising a loading device, a film tearing device, a distance changing device, a unloading device and a conveyor line. The loading device can transfer the sponge assembly to the film tearing device, and cooperate with the film tearing device to tear off the film from the sponge assembly. Thereafter, the loading device transfers the sponge assembly to the distance changing device, the distance changing device divides the sponge assembly into a plurality of sponge units arranged at equal intervals, and the unloading device transfers the sponge unit to the air-conditioning outdoor unit casing. In this way, the air-conditioning outdoor unit casing can be fully automatically sponged, and each step does not interfere with each other, reducing waiting time and improving production efficiency. At the same time, no manual operation is required, saving labor costs.

[0037] An exemplary embodiment of the present application provides an automatic sponge sticking device for an air conditioner outer housing, such as Figure 1 As shown, the automatic sponge sticking equipment for the air conditioner outer unit housing includes a loading device 10, a film tearing device 20, a distance-changing device 30, a unloading device 40 and a conveyor line 50. During operation, the air conditioner outer unit housing is conveyed to a waiting position along the conveyor line 50, and the waiting position is located below the unloading device 40, so that the unloading device 40 can transfer the sponge to the air conditioner outer unit housing. The loading device 10, the film tearing device 20 and the distance-changing device 30 are all arranged on one side of the conveyor line 50, and the unloading device 40 is erected above the conveyor line 50; the loading device 10 is used to transfer the sponge assembly to the film tearing device 20, and cooperate with the film tearing device 20 to tear off the film from the sponge assembly; the distance-changing device 30 is used to divide the sponge assembly into a plurality of sponge units arranged at equal intervals; the unloading device 40 is used to transfer the sponge unit to the air conditioner outer unit housing. In this way, the fully automatic sponge sticking of the air conditioner outer unit housing is realized, and each step does not interfere with each other, which reduces the waiting time and can improve the production efficiency. At the same time, no manual operation is required, which saves labor costs.

[0038] like Figure 2 As shown, the loading device 10 includes a first module 101 extending along the conveying direction of the conveyor line 50, and a loading lifting assembly 102 is arranged on the first module 101, and a material frame assembly 103 is arranged below the loading lifting assembly 102, and a sponge assembly with unpeeled film is placed in the material frame assembly 103. The first module 101 drives the loading lifting assembly 102 to reciprocate along the first module 101 to realize the transfer of the sponge assembly in the material frame assembly 103 to the secondary positioning assembly 203 of the film tearing device 20.

[0039] In one embodiment, the material frame assembly 103 is arranged on a frame with a preset height, a slide rail assembly is arranged above the frame, a material frame is arranged on the slide rail assembly, a sponge assembly is placed in the material frame, and the film of the sponge assembly in the material frame is located below the sponge. A material detection switch is arranged on the frame, a detection through hole is arranged on the material frame bottom plate 3021, and the detection end of the material detection switch is aligned with the detection through hole to detect whether there is a sponge assembly in the material frame. The material frame can slide along the slide rail assembly, and a handle is arranged at one end of the material frame. When the material detection switch detects that there is no sponge assembly in the material frame, the handle can be pulled to move the material frame to one end of the frame, and the square woven material frame is filled with sponge assemblies.

[0040] Continue to refer Figure 2 The feeding lifting assembly 102 includes a first bracket 1021 arranged on the first module 101, and a feeding lifting driving unit 1022 is arranged on the first bracket 1021. Preferably, the feeding lifting driving unit 1022 is an electric cylinder; a suction cup mounting plate 1023 is arranged on the protruding end of the feeding lifting driving unit 1022, a vacuum generator is installed on the top of the suction cup mounting plate 1023, and multiple groups of feeding suction cups 1024 are arranged below the suction cup mounting plate 1023, and the vacuum generator is connected to the feeding suction cups 1024. A guide plate is also arranged on the protruding end of the feeding lifting driving unit 1022, a guide sleeve is arranged on the guide plate, and a guide rod is slidably arranged in the guide sleeve, and the suction cup mounting plate 1023 at the bottom end of the guide rod is fixedly connected, and the guide plate, the guide sleeve and the guide rod cooperate with each other to guide the movement of the feeding lifting driving unit 1022. The loading and lifting driving unit 1022 can drive the loading suction cup 1024 to move in the vertical direction. When the sponge component needs to be adsorbed, the loading and lifting driving unit 1022 drives the loading suction cup 1024 to move downward. After the loading suction cup 1024 adsorbs the sponge component, the loading and lifting driving unit 1022 drives the loading suction cup 1024 to drive the adsorbed sponge component to move upward. Then, the first module 101 drives the loading and lifting component 102 to drive the sponge component to move along the first module 101 to the secondary positioning component 203 of the film tearing device 20.

[0041] like Figure 3 As shown, the film tearing device 20 includes a second module 201, and the extension direction of the second module 201 is perpendicular to the conveying direction; the film tearing device 20 also includes a secondary positioning component 203, and the secondary positioning component 203 is used to position the sponge component of the film to be torn off. The secondary positioning component 203 includes a positioning plate, and a limiting plate is provided on one side of the positioning plate, and a push plate assembly is provided on the other side. The push plate assembly includes a cylinder arranged under the positioning plate and a push plate arranged at the protruding end of the cylinder. The cylinder drives the push plate to push the side of the sponge component close to the limiting plate to achieve the positioning of the sponge component.

[0042] The second die set 201 is provided with a clamping jaw 2023b mechanism 202, and the second die set 201 drives the clamping jaw 2023b mechanism 202 to reciprocate along the second die set 201. Figure 4 As shown, the clamping jaw 2023b mechanism 202 includes a second bracket 2021 disposed on the second module 201, a third module 2022 is disposed on the second bracket 2021, the third module 2022 extends in the vertical direction, a clamping jaw assembly 2023 is disposed on the third module 2022, and the third module 2022 can drive the clamping jaw assembly 2023 to rise and fall in the vertical direction. The clamping jaw assembly 2023 includes a clamping jaw driving unit 2023a and a pair of clamping jaws 2023b disposed at the protruding end of the clamping jaw driving unit 2023a. Preferably, the clamping jaw driving unit 2023a is a clamping jaw 2023b cylinder, and the clamping jaw driving unit 2023a can drive the clamping jaw 2023b to open and close, so as to achieve the clamping and release of the film.

[0043] After the sponge component is positioned on the secondary positioning component 203, the loading suction cup 1024 absorbs the sponge component again. At this time, the clamping jaw assembly 2023 clamps the film at the bottom of the sponge component, and the loading suction cup 1024 drives the sponge component to lift upward, so that a certain distance is maintained between the sponge component and the secondary positioning component 203. The clamping jaw assembly 2023 rises together with the sponge component, and then the clamping jaw assembly 2023 moves along the second module 201 toward the end away from the conveyor line 50, tears off the film on the sponge component, and throws the torn film into a collection basket arranged below one end of the distance changing device 30. After that, the loading device 10 transfers the sponge component with the film torn off to the distance changing device 30, and the clamping jaw 2023b mechanism 202 moves along the second module 201 toward the conveyor line 50 to the initial position, and tears off the film for the next sponge component.

[0044] like Figures 5 to 7 As shown, the pitch changing device 30 includes a pitch changing drive unit 301 and a plurality of pitch changing assemblies 302 arranged side by side; preferably, the pitch changing drive unit 301 is a cylinder. The pitch changing assembly 302 is arranged on a slide rail pair 303, and each pitch changing assembly 302 is connected to a connecting rod assembly 304; in this way, the pitch changing assembly 302 can slide on the slide rail pair 303, and can realize the equal distance between the plurality of pitch changing assemblies 302. The pitch changing drive unit 301 is connected to one of the pitch changing assemblies 302, and the pitch changing drive unit 301 drives the pitch changing assembly 302 to move along the slide rail, realizing the separation and combination between the plurality of pitch changing assemblies 302.

[0045] The variable pitch component 302 includes a bottom plate 3021, on which a support plate 3022 and a traceless sponge suction cup component 3023 are arranged, and on the support plate 3022, a top plate 3024 and an adhesive sponge are arranged in sequence from bottom to top; the traceless sponge suction cup component 3023 passes through the top plate 3024 and the adhesive sponge, and is used to absorb the sponge component. The surface of the adhesive sponge and the surface of the traceless sponge suction cup will not adhere to the adhesive layer. When the feeding device 10 transfers the sponge component after the adhesive film is torn off to the adhesive sponge, the suction effect of the feeding suction cup 1024 on the sponge component is slowly reduced. Therefore, the traceless sponge suction cup component 3023 is arranged below the sponge component to absorb the sponge component so that the sponge component is placed on the adhesive sponge. At the same time, a pressing component 3025 is arranged above the adhesive sponge, and the pressing component 3025 is used to press the sponge component during the variable pitch process. Preferably, the clamping assembly 3025 includes a cylinder arranged on one side of the support plate 3022, and a clamping block is arranged at the protruding end of the cylinder. The cylinder can drive the clamping block to rotate to make way for the loading suction cup 1024 to place the sponge assembly and the unloading suction cup assembly 502 to adsorb the sponge unit.

[0046] like Figure 7 As shown, the connecting rod assembly 304 includes a plurality of first connecting rods 3041 hinged end to end in sequence and a plurality of second connecting rods 3042 hinged end to end in sequence, the first connecting rod 3041 and the second connecting rod 3042 at the end are hinged to each other, and the middle part of the first connecting rod 3041 and the middle part of the second connecting rod 3042 are hinged to each other through a pin shaft to be arranged crosswise. The bottom plate 3021 of each set of variable pitch components 302 is connected to the middle pin shaft, and preferably, the spacing of the middle pin shafts connected to each set of variable pitch components 302 is equal. A variable pitch positioning plate is arranged below the middle position of the connecting rod assembly 304, and the hinge shafts of the first connecting rod 3041 and the second connecting rod 3042 are clamped on the variable pitch positioning plate to realize the separation of the variable pitch components 302 from the middle part of the connecting rod assembly 304 to the two ends or from the two ends to the middle part.

[0047] In one embodiment, if Figure 6 As shown, the pitch changing device 30 includes four pitch changing components 302, which are respectively the first pitch changing component 302, the second pitch changing component 302, the third pitch changing component 302 and the fourth pitch changing component 302 from left to right. The pitch changing drive unit 301 is connected with the fourth pitch changing component 302. When the extended end of the pitch changing drive unit 301 is extended, the fourth pitch changing component 302 is driven to slide toward one end of the slide rail component. Under the action of the connecting rod mechanism, the third pitch changing component 302 is driven to slide in the same movement direction as the fourth pitch changing component 302 at the same time; the first pitch changing component 302 and the second pitch changing component 302 are driven to slide toward the other end of the slide rail component, so as to realize the equal spacing separation between the first pitch changing component 302, the second pitch changing component 302, the third pitch changing component 302 and the fourth pitch changing component 302.

[0048] In the present application, the sponge assembly used is a sponge assembly including four sponge units, and the sponge units are connected by tearing guide lines. In this way, when the feeding lifting assembly 102 transfers the sponge assembly after tearing the adhesive film to the variable distance assembly 302, the pressing assembly 3025 presses the top of the sponge assembly, and the variable distance assembly 302, driven by the variable distance driving unit 301, can separate the sponge assembly into four sponge units along the tearing guide line. Then the unloading device 40 transfers the sponge unit to the air conditioner outer shell, so that the sponge unit is attached to the air conditioner outer shell.

[0049] like Figure 8 As shown, the unloading device 40 includes a fourth module 501, the extension direction of the fourth module 501 is perpendicular to the conveying direction; the fourth module 501 is provided with spaced unloading suction cup assemblies 502. Preferably, there are two unloading suction cup assemblies 502, and the spacing between the two unloading suction cup assemblies 502 is adapted to the spacing after the variable distance assembly 302 is separated. Preferably, the spacing between the two unloading suction cup assemblies 502 is adapted to the distance between the first variable distance assembly 302 and the third variable distance assembly 302. The two unloading suction cup assemblies 502 can absorb two sponge units at the same time, and transfer the two sponge units to the air conditioner outer shell at the same time, so as to achieve the attachment of two sponge units at one time, thereby improving the sponge attachment efficiency.

[0050] In this application, the terms "comprises", "comprising" or any other variations thereof are intended to cover non-exclusive inclusion, so that an article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such article or device. In the absence of more restrictions, the elements defined by the sentence "comprising..." do not exclude the presence of other identical elements in the article or device comprising the elements.

[0051] Although the preferred embodiments of the present application have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.
