Specifically, when the glue gun 2 is required to seal the workpiece P, the workpiece P is placed on the machine table 1 or the fixing frame 4, and then the driving unit 3 is started to drive the glue gun 2 to move, so that the nozzle of the glue gun 2 corresponds to the workpiece P, and the workpiece P can be machined by starting the glue gun 2.

After the workpiece P is processed, starting the driving unit 3 to drive the glue gun 2 to move away from the workpiece P and towards the cleaning opening 411 until the nozzle of the glue gun 2 stretches into the cleaning opening 411 and abuts against the dust-free cloth 51, and starting the rotating unit 6 to drive the rotating disc 5 to rotate, wherein the dust-free cloth 51 rotates along with the rotating disc 5 to wipe the nozzle of the glue gun 2; in the process of cleaning the glue gun 2, a worker can take down the processed workpiece P and replace the workpiece P with a new workpiece P, and after the glue gun 2 is cleaned, the workpiece P is driven to the new workpiece P again by the driving unit for processing.

It should be noted that, after the dust-free cloth 51 is fully covered with the foreign matter, the worker needs to disassemble the dust-free cloth 51 from the turntable 5 by disassembling the dust cover 41, and then replace the dust-free cloth 51 with a new one; in order to facilitate the disassembly and assembly of the dust-free cloth 51, in the embodiment of the present utility model, the dust-free cloth 51 may be fixed on the turntable 5 by using double-sided adhesive tape, or directly fixed by using screws, and the present utility model is not limited thereto due to various methods.

In addition, in the actual use process, after the nozzle of the glue gun 2 enters the cleaning opening 411, the rotating unit 6 is started again to drive the turntable 5 to rotate within a specific range, so that the unused dust-free cloth 51 is prevented from being exposed to the cleaning opening 411 in advance and being polluted by dust.

In summary, the dust cover 41 is designed on the fixing frame 4 for shielding the dust-free cloth 51, so that dust pollution caused by the fact that the dust-free cloth 51 is exposed outside is avoided; the driving unit 3 is designed to control the glue gun 2 to move so that the nozzle of the glue gun 2 can enter and exit the cleaning opening 411 and abut against the dust-free cloth 51; finally, the rotating unit 6 is designed to drive the turntable 5, so that the dust-free cloth 51 can move and wipe the nozzle of the glue gun 2, thereby realizing the cleaning of the nozzle; the whole process is automatically carried out, so that the working efficiency can be effectively improved, the workers can be prevented from being scalded by residual glue, and the operation safety is improved.

Referring to fig. 4-9, the rotating unit 6 is various, for example, a servo motor, an electric gearbox and the like can be directly adopted, and the rotating unit 6 is not limited in the utility model, but for convenient installation, the rotating unit 6 comprises a first motor 61, a driving wheel 62, a driven wheel 63 and a transmission belt 64, wherein the first motor 61 is installed on the fixed frame 4, and the driving wheel 62 is installed on an output shaft of the first motor 61; the driven wheel 63 is arranged on the turntable 5, and a transmission belt 64 is used for linking the driving wheel 62 and the driven wheel 63; the turntable 5 is driven to rotate by a first motor 61.

Specifically, when in use, the first motor 61 is controlled to start and stop, the turntable 5 is driven to rotate within a specific range and then stops, so that the nozzle of the glue gun 2 is immediately stopped after the dust-free cloth 51 is wiped, and the unused dust-free cloth 51 is prevented from being exposed at the cleaning opening 411.

It should be noted that the technique of controlling the intermittent start-stop of the first motor 61 by a program is very common in the mechanical field, and it should be understood by those skilled in the art that the specific principle and circuit structure thereof will not be further described in the present utility model.

Referring to fig. 1, 10 and 11, in order to facilitate the placement and disassembly of the workpiece P, the utility model further includes a carrier plate 7 and a positioning jig 8, the dust cover 41 is further provided with a movable opening 412 for connecting the rotating cavity 410 with the outside, and the carrier plate 7 is disposed at the movable opening 412 and fixedly connected with the turntable 5; the positioning jig 8 is mounted on the carrier plate 7 and is used for clamping the workpiece P.

On the other hand, because the specifications of the workpiece P are various, the range of the glue sealing angle required by part of the workpiece P may be less than 360 °, and at this time, the matching design of the indicator 7k and the annular angle scale 41k can also help the worker to accurately control the rotation range of the workpiece P.

It should be noted that, in the case that the turntable 5 and the carrier plate 7 do not need to rotate 360, the dust-free cloth 51 cannot be reset obviously only by rotating the turntable 5 in one direction, so after the glue gun 2 finishes processing the workpiece P, the turntable 5 needs to be controlled to rotate again by a proper angle (the angle is complementary to the angle of rotation of the workpiece P) by the rotating unit 6, so that the dust-free cloth 51 returns to the original position again, and finally, the nozzle of the glue gun 2 is controlled to enter the cleaning opening 411 by the driving unit 3.
