The sponges can absorb the vibration and noise generated during the operation of the air conditioner, reduce the impact on the external environment, make the air conditioner operate more quietly, and at the same time, protect the components inside the air conditioner and extend its service life. During the assembly process of the outer casing of the air conditioner, for the convenience of transportation, storage, feeding, etc., the commonly used sponge is a sponge assembly. A sponge assembly includes multiple sponge units, and the sponge units are connected by tearing guide lines. Before attaching the sponge units to the outer casing of the air conditioner, the sponge assembly needs to be divided into independent and unconnected sponge units along the tearing guide lines.

[0003] In the prior art, when attaching sponge units to the traditional outer casing of an air conditioner, it is an artificial operation.

Specific embodiments

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other arbitrarily.

[0022] Sponges are usually installed on the outer casing of an air conditioner. The sponges can absorb the vibration and noise generated during the operation of the air conditioner to reduce the impact on the external environment, make the air conditioner operate more quietly, and at the same time, protect the components inside the air conditioner and extend the service life. During the assembly process of the outer casing of the air conditioner, for the convenience of transportation, storage, feeding, etc., the commonly used sponge is a sponge assembly. A sponge assembly includes multiple sponge units, and the sponge units are connected by tearing guide lines. Before attaching the sponge units to the outer casing of the air conditioner, the sponge assembly needs to be divided into independent and unconnected sponge units along the tearing guide lines.

[0023] In the prior art, when attaching sponge units to the traditional outer casing of an air conditioner, it is an artificial operation. Usually, the outer casing of the air conditioner is placed on a working platform, and the operator manually tears off the adhesive film on the back of the sponge assembly, then tears it along the tearing guide lines to obtain individual sponge units, and then attaches the sponge units to the outer casing of the air conditioner. Therefore, the overall production efficiency is low and the production capacity is low. At the same time, after the adhesive film is torn off and the sponge assembly is divided, due to manual operation, some impurities may adhere to the surface of the adhesive layer, contaminating the adhesive layer, and thus affecting the adhesion of the sponge units.

[0024] Based on this, an exemplary embodiment of the present application provides a pitch-changing device, which includes a pitch-changing drive unit and a plurality of pitch-changing components arranged side by side. The pitch-changing components are arranged on a slide rail pair, a link component is arranged in the middle of the slide rail pair, and each pitch-changing component is connected to the link component. In this way, when a sponge component is arranged on the pitch-changing component, driven by the pitch-changing drive unit, the pitch-changing component slides on the slide rail, and the plurality of pitch-changing components can be separated and combined, so that the sponge component can be divided into a plurality of sponge units along the tearing guide line, realizing the full-automatic division of the sponge component, which not only improves the production efficiency, but also, during the division process of the sponge component, no manual intervention is required, reducing the probability of contaminating the glue layer and avoiding the influence on the sticking adhesion of the sponge unit due to glue layer contamination.

[0025] An exemplary embodiment of the present application provides a pitch-changing device, as Figure 1 and 2 shown, the pitch-changing device includes a pitch-changing drive unit 301 and a plurality of pitch-changing components 302 arranged side by side; preferably, the pitch-changing drive unit 301 is a cylinder. The pitch-changing components 302 are arranged on a slide rail pair 303, and each pitch-changing component 302 is connected to a link component 304; in this way, the pitch-changing component 302 can slide on the slide rail pair 303, and the equal-distance separation and combination between the plurality of pitch-changing components 302 can be realized. The pitch-changing drive unit 301 is connected to one of the pitch-changing components 302, and the pitch-changing drive unit 301 drives the pitch-changing component 302 to move along the slide rail, realizing the separation and combination between the plurality of pitch-changing components 302.

[0026] Continuing to refer to Figure 1 , the pitch-changing component 302 includes a bottom plate 3021, a support plate 3022 and a traceless sponge suction cup assembly 3023 are arranged on the bottom plate 3021, a top plate and a back glue sponge 3024 are sequentially arranged on the support plate 3022 from bottom to top; the traceless sponge suction cup assembly 3023 passes through the top plate and the back glue sponge 3024 and is used for adsorbing the sponge component. The surfaces of the back glue sponge 3024 and the traceless sponge suction cup will not adhere to the glue layer. When the feeding device transfers the sponge component after tearing the glue film to the back glue sponge 3024, due to the slow reduction of the suction force of the feeding suction cup on the sponge component, therefore, the traceless sponge suction cup assembly 3023 is arranged to adsorb the sponge component below the sponge component, so that the sponge component is placed on the back glue sponge. The traceless sponge suction cup assembly 3023 includes a suction cup mounting plate arranged on the bottom plate 3021, and two groups of traceless sponge suction cups are arranged at intervals on the suction cup mounting plate, and the two groups of traceless sponge suction cups can simultaneously adsorb the bottom of the sponge component to enhance the adsorption ability.

[0027] In one embodiment, as Figure 3As shown in the figure, a pressing assembly 3025 is provided above the adhesive sponge 3024. The pressing assembly 3025 is used to press the sponge assembly during the pitch change process. Preferably, the pressing assembly 3025 includes a pressing drive unit provided on one side of the support plate 3022. The pressing drive unit is preferably a cylinder. A pressing block is provided at the end of the piston rod of the pressing drive unit. The pressing drive unit can drive the pressing block to perform reciprocating motion in the vertical direction and rotational motion with the piston rod of the pressing drive unit as the rotation center, so as to make way for placing the sponge assembly and transferring the divided sponge units.

[0028] As Figure 4 shown in the figure, the link assembly 304 includes a plurality of first links 3041 hinged end to end in sequence and a plurality of second links 3042 hinged end to end in sequence. The first link 3041 and the second link 3042 at the ends are hinged to each other. The middle of the first link 3041 and the middle of the second link 3042 are hinged by a pin shaft and are arranged in a cross shape with each other. The bottom plate 3021 of each pitch change assembly 302 is connected to the middle pin shaft. Preferably, the distances between the middle pin shafts connected to each pitch change assembly 302 are equal. A pitch change positioning plate is provided below the middle position of the link assembly 304. The hinge shafts of the first link 3041 and the second link 3042 are clamped on the pitch change positioning plate to realize the separation of the pitch change assembly 302 from the middle of the link assembly 304 to both ends or the approach from both ends to the middle.

[0029] In one embodiment, as Figure 2 shown in the figure, the pitch change device includes four pitch change assemblies 302, which are the first pitch change assembly, the second pitch change assembly, the third pitch change assembly, and the fourth pitch change assembly from left to right. The pitch change drive unit 301 is connected to the fourth pitch change assembly. When the extending end of the pitch change drive unit 301 extends, it drives the fourth pitch change assembly to slide towards one end of the slide rail pair 303. Under the action of the link mechanism, it simultaneously drives the third pitch change assembly to slide in the same movement direction as the fourth pitch change assembly; drives the first pitch change assembly and the second pitch change assembly to slide towards the other end of the slide rail pair 303, realizing the equal-spacing separation between the first pitch change assembly, the second pitch change assembly, the third pitch change assembly, and the fourth pitch change assembly.

[0030] In this application, the used sponge assembly is a sponge assembly including four sponge units, and the sponge units are connected by tearing guide lines. Thus, when the sponge assembly after tearing the adhesive film is transferred to the pitch change assembly 302, the pressing assembly 3025 presses the top of the sponge assembly. The pitch change assembly 302 can separate the sponge assembly into four sponge units along the tearing guide lines under the drive of the pitch change drive unit 301. Then, the sponge units are transferred to the air conditioner outdoor unit housing through the blanking device, and the sponge units are attached to the air conditioner outdoor unit housing.
