[0035] The utility model provides a sponge automatic pasting device, which can be used to paste sponge 22 on the surface of the device 1. In this embodiment, the device 1 is Figure 1 Taking the air-conditioning outdoor unit structure shown as an example, the automatic sponge sticking device can realize automatic sticking of sponge on the top surface of the air-conditioning outdoor unit; of course, other devices 1 with similar structures can also be used to stick sponge 22 on the surface, which is not limited here.

[0036] like Figure 2 、 Figure 3 As shown, the automatic sponge pasting device includes a positioning mechanism 3, a material bin 4, a material moving mechanism 5 and a pasting mechanism 6; wherein:

[0037] The positioning mechanism 3 is provided on the pasting station, and the positioning mechanism 3 can limit the position of the device 1 on the pasting station, so that the device 1 is fixed on the pasting station;

[0038] The silo 4 is provided on the loading station, and a plurality of sponge blocks 2 to be pasted can be stored in the silo 4. The sponge blocks 2 are composed of release paper 21 and sponge 22 attached to the release paper 21. The sponge blocks 2 in the silo 4 can be stored in a variety of storage methods, such as stacking them layer by layer or storing them in a roll state. The silo 4 is provided with a discharge port adapted to the sponge blocks 2, which allows the sponge blocks 2 to be removed.

[0039] The material moving mechanism 5 is also provided on the loading station, and can move the sponge material block 2 in the hopper 4 out of the discharge port and fix it on the stripping station; the material moving mechanism 5 can adopt various structures such as a clamping claw, a suction cup, etc.

[0040] The pasting mechanism 6 is arranged on the pasting station, and the pasting mechanism 6 can reciprocate between the peeling station and the pasting station, and can peel the sponge 22 on the peeling station from the release paper 21 and move the sponge 22 to the pasting station, and then paste the sponge 22 on the surface of the device 1.

[0041] The automatic sponge pasting device adopts the above structure, through the mutual cooperation of the positioning mechanism 3, the material bin 4, the material moving mechanism 5 and the pasting mechanism 6, can realize the automatic peeling and automatic pasting of the sponge 22. Compared with the traditional manual operation method, it not only reduces the personnel cost, but also greatly improves the production efficiency and improves the pasting quality.

[0042] In some embodiments, as Figure 4 As shown, the material moving mechanism 5 includes a first suction cup assembly 51, a first lifting assembly 52 and a first transverse movement assembly 53; specifically, the first suction cup assembly 51 can be used to suck the sponge material block 2, the first lifting assembly 52 can control the up and down movement of the first suction cup assembly 51, and the first transverse movement assembly 53 can control the lateral movement of the first suction cup assembly 51.

[0043] The automatic sponge pasting device adopting the above structure, through the mutual cooperation of the first suction cup assembly 51, the first lifting assembly 52 and the first transverse movement assembly 53, can not only move the sponge material block 2 located in the hopper 4 out of the discharge port and fix it on the stripping station, but also has a simple structure, reliable operation and strong applicability.

[0044] In some embodiments, continuing as Figure 4 As shown, the first suction cup assembly 51 includes two left-right symmetrical vacuum suction cups, and the two left-right symmetrical vacuum suction cups can respectively absorb the left and right sides of the sponge material block 2.

[0045] The automatic sponge pasting device using the above structure can make the first suction cup assembly 51 more evenly stressed when adsorbing the sponge block 2 through the two left-right symmetrical vacuum suction cups, thereby achieving a better adsorption effect and enhancing the reliability of the automatic sponge pasting device.

[0046] In some embodiments, as Figure 5 、 Figure 6As shown, a number of sponge material blocks 2 can be stacked layer by layer in the silo 4; the discharge port is arranged at the bottom of the side of the silo 4, allowing the sponge material blocks 2 on the bottom layer to move out laterally; the stripping station is arranged on the plane at the discharge port, connected to the bottom of the silo 4, and the bottom of the silo 4 and the bottom of the stripping station are provided with a connected hollow waist hole, and the hollow waist hole can allow the first suction cup assembly 51 to enter and move laterally.

[0047] In the automatic sponge pasting device with the above structure, the first suction cup assembly 51 enters the hopper 4 from the hollow waist hole at the bottom and sucks the sponge material block 2 at the bottom of the hopper, and then moves horizontally to move the sponge material block 2 out of the discharge port to the stripping station, and continues to maintain adsorption, waiting for the operation of the pasting mechanism 6. This material moving method can further improve production efficiency and is more stable and reliable.

[0048] In some embodiments, as Figure 7 As shown, the silo 4 is provided with a first sensor 41, which can be used to detect whether the sponge material block 2 is stored in the silo 4; the first sensor 41 can be set on the side of the silo 4 as shown in this embodiment, or it can be set at other positions such as above the silo 4, as long as it can detect whether the sponge material block 2 is stored in the silo 4.

[0049] The automatic sponge pasting device using the above structure can, through the setting of the first sensor 41, provide a feedback signal to remind people to add material when there is no sponge material block 2 in the hopper 4, so as to avoid the device running idle and causing waste of production resources or damage to the device, thereby improving production efficiency and enhancing the reliability and intelligence level of the automatic sponge pasting device.

[0050] In some embodiments, as Figure 5 As shown, a second sensor 42 is provided at the stripping station, and the second sensor 42 can be used to detect whether the sponge 22 is on the stripping station.

[0051] The automatic sponge pasting device adopts the above structure. Through the setting of the second sensor 42, when it is detected that there is no sponge 22 on the peeling station, a feedback signal can be used to control the material moving mechanism 5 to move the sponge material block 2 in the hopper 4 out of the discharge port; when it is detected that there is a sponge 22 on the peeling station, a feedback signal can be used to control the pasting mechanism 6 to move to the peeling station to peel the sponge 22 from the release paper 21 and transfer it to the pasting station; thereby, the idle operation of the device can be avoided to cause waste of production resources or damage to the device, production efficiency can be improved, and the reliability and intelligence level of the automatic sponge pasting device can be enhanced.

[0052] In some embodiments, as Figure 7 、 Figure 8 As shown, a release paper pressing assembly 7 is also provided at the stripping station; specifically, the release paper pressing assembly 7 includes a release paper pressing block 71 and a pressing drive component 72, and the pressing drive component 72 can control the release paper pressing block 71 to move up and down, thereby driving the release paper pressing block 71 to press the release paper 21 after the sponge 22 has been stripped.

[0053] The automatic sponge pasting device using the above structure, through the provision of the release paper pressing assembly 7, can not only strengthen the fixing effect of the sponge material block 2 on the stripping station, but also prevent the release paper 21 after the sponge 22 has been stripped from interfering with the operation of the device, thereby further improving the reliability of the automatic sponge pasting device.

[0054] In some embodiments, as Figure 9 As shown, the pasting mechanism 6 includes a second suction cup assembly 61, a second lifting assembly 62 and a second transverse movement assembly 63; specifically, the second suction cup assembly 61 can be used to suck the sponge 22 tightly, the second lifting assembly 62 can control the up and down movement of the second suction cup assembly 61, and the second transverse movement assembly 63 can control the lateral movement of the second suction cup assembly 61.

[0055] The automatic sponge pasting device using the above structure, through the mutual cooperation of the second suction cup assembly 61, the second lifting assembly 62 and the second transverse movement assembly 63, can not only peel the sponge 22 on the peeling station from the release paper 21 and transfer it to the pasting station for pasting, but also has a simple structure, reliable operation and strong applicability.

[0056] In some embodiments, continuing as Figure 9 As shown, the second suction cup assembly 61 includes two left-right symmetrical vacuum suction cups, and the two left-right symmetrical vacuum suction cups can respectively adsorb the left and right sides of the sponge 22.

[0057] The automatic sponge sticking device using the above structure can make the second suction cup assembly 61 more evenly stressed when adsorbing the sponge 22 through the two left-right symmetrical vacuum suction cups, thereby achieving a better adsorption effect and enhancing the reliability of the automatic sponge sticking device.

[0058] In some embodiments, continuing as Figure 9 As shown, a third sensor 64 is further provided on the second suction cup assembly 61 , and the third sensor 64 can be used to detect whether the sponge 22 is sucked onto the second suction cup assembly 61 .

[0059] The automatic sponge pasting device using the above structure can detect the result of the second suction cup assembly 61 adsorbing the sponge 22 through the setting of the third sensor 64. If the adsorption is successful, the sponge 22 will be moved to the pasting station for pasting. If the adsorption fails, it will be re-adsorbed or an alarm will be prompted, which can improve the reliability and intelligence level of the automatic sponge pasting device.

[0060] In some embodiments, a metal proximity switch is further provided on the second suction cup assembly 61; a metal proximity switch is a non-contact sensor that can generally be used to detect the presence or position of a metal object. Therefore, when the surface of the device 1 is made of metal, the metal proximity switch can detect the distance between the second suction cup assembly 61 and the surface of the device 1 at the pasting station.

[0061] The automatic sponge pasting device adopts the above structure, and the distance between the second suction cup assembly 61 and the surface of the device 1 is detected by the metal proximity switch, so that the feedback signal can be used to control the downward pressure height of the second suction cup assembly 61. This not only can better control the pressure of the second suction cup assembly 61 when controlling the sponge 22 downward and improve the pasting quality, but also can be applied to the sponge 22 pasting of more devices 1 with different specifications, and has better versatility.

[0062] In some embodiments, a fourth sensor 65 is provided at the pasting station, and the fourth sensor 65 can be used to detect whether the sponge 22 on the surface of the device 1 is pasted properly; in this embodiment, Figure 9 As shown, the fourth sensor 65 is fixed on the moving guide rail of the pasting mechanism 6 located above the pasting station. In actual application, it can also be set at other possible positions as long as it can detect whether the sponge 22 on the surface of the device 1 is pasted properly.

[0063] The automatic sponge pasting device with the above structure can detect the pasting effect of the sponge 22 on the surface of the device 1 through the setting of the fourth sensor 65, and issue an alarm when there are abnormal situations such as wrong pasting or missing pasting, thereby achieving consistent control of pasting quality and improving production quality.

[0066] In some embodiments, as Figure 10 、 Figure 11 As shown, the positioning mechanism 3 includes a blocking component 31 and a lateral positioning component 32; specifically, the blocking component 31 includes a blocker 311 and a blocking drive component 312, and the blocker 311 can block the conveying base plate 82 from moving forward (referring to the conveying movement direction of the conveyor belt body 81) under the drive of the blocking drive component 312; the lateral positioning component 32 includes a lateral positioning rod 321 and a lateral positioning drive component 322, and the lateral positioning rod 321 can limit the device 1 on the side of the pasting station (referring to the left and right sides of the conveying movement direction relative to the conveyor belt body 81) under the drive of the lateral positioning drive component 322.

[0067] The automatic sponge pasting device using the above structure can block the forward movement of the conveying base plate 82 through the setting of the blocking component 31, thereby limiting the device 1 in the front and rear directions; and then limiting the device 1 in the left and right directions through the setting of the lateral positioning component 32; thereby limiting the device 1 at the pasting station, achieving precise positioning and improving the pasting quality.

[0068] In some embodiments, the positioning mechanism 3 also includes a forward positioning component 33; specifically, the forward positioning component 33 includes a forward positioning rod 331 and a forward positioning drive component 332. The forward positioning rod 331, driven by the forward positioning drive component 332, can limit the device 1 in front of the pasting station.

[0069] The automatic sponge pasting device with the above structure can further enhance the limiting effect of the device 1 in the front and rear directions through the setting of the forward positioning component 33, further improve the positioning effect, and further improve the pasting quality.

[0070] In some embodiments, as Figure 12 As shown, the end surfaces of the lateral positioning rod 321 and / or the forward positioning rod 331 in contact with the device 1 are provided with a plurality of unpowered rollers; for example, only the end surface of the lateral positioning rod 321 in contact with the device 1 is provided with a plurality of unpowered rollers, or only the end surface of the forward positioning rod 331 in contact with the device 1 is provided with a plurality of unpowered rollers, or more preferably, as shown in this embodiment, the end surfaces of the lateral positioning rod 321 and the forward positioning rod 331 in contact with the device 1 are both provided with a plurality of unpowered rollers.

[0071] The automatic sponge pasting device of the above structure uses the unpowered roller to contact the device 1. When subjected to friction, the unpowered roller will rotate, which can eliminate the friction in a certain direction, thereby reducing the friction when in contact with the device 1 and avoiding damage to the device 1 due to hard contact.

[0072] In some embodiments, continuing as Figure 10 、 Figure 11 As shown, a fifth sensor 83 is further provided on the pasting station, and the fifth sensor 83 can be used to detect whether the device 1 is placed on the pasting station.

[0073] The automatic sponge pasting device using the above structure, through the setting of the fifth sensor 83, when it detects that the device 1 is correctly placed on the pasting station, then feedback signals are used to control the relevant actions of the material moving mechanism 5 and the pasting mechanism 6, thereby avoiding the waste of production resources or damage to the device caused by idle operation of the device, and improving the reliability and intelligence level of the automatic sponge pasting device.

[0074] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention.
