[0028] As shown in the drawings, Figures 1 to 4 the glue filling machine glue wiping device of the embodiment includes a device main body 1, a roll mechanism 2 and a plurality of cleaning clamp heads 3.

[0029] The device body 1 is used for being installed on a glue filling machine (not shown in the figure); and can be installed in an area within a moving range of a glue head (not shown in the figure).

[0030] As Figure 1 , the roll mechanism 2 comprises a cleaning roll 21, a receiving roll 22, a discharging roll 23 and a driver 24.

[0031] Referring to Figure 2 , the receiving roll 22 and the discharging roll 23 are spaced left and right and rotatably installed on the front side of the device body 1; one end of the cleaning roll 21 is wound in the discharging roll 23, and the other end is wound in the receiving roll 22; the driver 24 drives the receiving roll 22 to rotate, and the cleaning roll 21 is wound; the cleaning roll 21 is contacted by the glue head to keep the excess glue on the cleaning roll 21, so as to achieve the purpose of glue wiping and cleaning, and the cleaning roll 21 can be rotated and wound to facilitate automatic updating.

[0032] Referring to Figure 3 , the number of the plurality of cleaning chucks 3 is set corresponding to the number of the glue heads of the glue filling machine; and three cleaning chucks 3 are taken as an example in the embodiment.

[0033] Each cleaning chuck 3 is installed left and right on the device body 1, and each cleaning chuck 3 comprises two chucks 31 which can be close to or separated from each other, each chuck 31 is close to and located below the cleaning roll 21 between the receiving roll 22 and the discharging roll 23, and the cleaning roll 21 extends forward and backward in the width direction.

[0034] By setting the plurality of cleaning chucks 3, not only the cleaning strength of the glue head can be increased, but also all the glue heads can be cleaned in batches to improve the cleaning efficiency; and since each cleaning chuck 3 has two chucks 31 which can be separated from and close to each other, when the glue head moves and contacts the cleaning roll 21, the glue head can be further pressed down to the cleaning roll 21, and at the same time, the two chucks 31 are opened, so that the glue needle tube of the glue head can drive the cleaning roll 21 to enter between the two chucks 31, then the two chucks 31 are controlled to be clamped, the glue needle tube of the glue head and the cleaning roll 21 are clamped, and finally the glue head is controlled to rise and leave the cleaning roll 21 and the two clamped chucks 31; thus, the cleaning roll 21 can be wrapped around the glue needle tube by the two chucks 31 to wipe the glue, which can effectively improve the wiping cleanliness of the glue needle tube and ensure the quality of subsequent glue filling.

[0035] In the embodiment, the cleaning chuck 3 further comprises a pneumatic finger 32, and the pneumatic finger 32 refers to the prior art structure; the pneumatic finger 32 is fixed on the front side of the device body 1, and the pneumatic fingers 32 of the cleaning chucks 3 can be spaced and adjustably installed on the mounting groove 11 provided on the front side of the device body 1, so as to adjust the cleaning chucks 3 left and right according to the position of the glue head.

[0036] Two said clamping head 31 are respectively connected and fixed on the two clamping jaws 321 on the top of the pneumatic finger 32. By moving the two clamping jaws 321 of the pneumatic finger 32 forward and backward, the two clamping heads 31 are moved forward and backward to approach or separate from each other.

[0037] For example Figure 3 The opposite faces of the two clamping heads 31 can be respectively provided with cleaning soft pads 311 to reduce damage to the glue needle tube.

[0038] Further, the roll mechanism 2 further comprises a first guide roller 25 and a second guide roller 26, which are respectively arranged on the front top of the device body 1 above the material collecting wheel 22 and the material releasing wheel 23; one end of the cleaning roll 21 is wound on the material releasing wheel 23, and the other end is wound on the material collecting wheel 22 in turn after passing through the first guide roller 25 and the second guide roller 26; each cleaning clamp 3 can also be installed on the top of the device body 1 and below the cleaning roll 21 between the first guide roller 25 and the second guide roller 26. In this way, the height of the cleaning clamp 3 and the cleaning roll 21 can be saved to facilitate the glue dispensing head to quickly contact the cleaning roll 21 and the cleaning clamp 3 from top to bottom for cleaning.

[0039] In this embodiment, a guide wheel 27 and a tensioning wheel 28 are arranged between the material releasing wheel 23 and the first guide roller 25, and the tensioning wheel 28 is elastically attached to the guide wheel 27. The structure of the tensioning wheel 28 can refer to the prior art, and the tensioning wheel 28 is pressed against the guide wheel 27 by a tension spring 281.

[0040] The cleaning roll 21 passes through the tensioning wheel 28 and the guide wheel 27; the drive 24 can be installed between the material releasing wheel 23 and the material collecting wheel 22 and simultaneously drives the guide wheel 27 and the material collecting wheel 22 to rotate, and the drive 24 can be a stepping motor. In this way, the material releasing and collecting of the cleaning roll 21 can be facilitated, and the tensioning degree of the cleaning roll 21 can be ensured.

[0041] For example Figure 4As shown, the material receiving wheel 22 and the material discharging wheel 23 of the embodiment have a material receiving shaft 221 and a material discharging shaft 231 respectively installed on the device body 1, the guide wheel 27 has a guide shaft 271 installed on the device body 1, and the driver 24 has a driving end 241 connected with a driving wheel 242 installed on the device body 1.
