[0002] In the process of automobile manufacturing, in order to ensure the anti-rust, anti-corrosion, noise reduction and other effects of the automobile, the body manufacturing companies will extrude sealants, expansion glue, folding glue and other process flows on the joints of the body. Nowadays, with the improvement of intelligent production, many glue extrusion operation positions have evolved from manual glue extrusion to glue extrusion operation of glue extrusion process equipment. At present, most of them adopt the method of installing glue extrusion guns at the end of the robotic arm to realize the high degree of freedom of movement of the glue extrusion gun, which is convenient for glue extrusion work at various positions.

[0003] Although the glue extrusion equipment has the advantages of fast operation and high accuracy, it also has some disadvantages. For example, after the glue extrusion equipment performs continuous glue extrusion operation, some residual glue will stick to the glue extrusion outlet due to the viscosity of the glue itself, affecting the subsequent glue extrusion quality, resulting in defects such as the glue diameter not meeting the process requirements and residual glue adhering to the car body and affecting the appearance. It is necessary to add special personnel to check and rework the glue that does not meet the process requirements.

[0051] The present invention is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technicians in this field can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0052] Example:

[0053] like Figures 1 to 4 As shown, the present invention provides a glue extrusion gun nozzle cleaning device, including a base 101, a mounting sleeve 102 is arranged above the base 101, a rotating cylinder 201 is arranged in the mounting sleeve 102 so as to be liftable, the rotating cylinder 201 is in contact with the inner wall of the mounting sleeve 102, and the rotating cylinder 201 is connected to the mounting sleeve 102 through a driving component to synchronously drive the rotating cylinder 201 to rotate when the rotating cylinder 201 is lifted or lowered, the driving component includes a guide column 202 arranged on the outer circumferential surface of the rotating cylinder 201, a spiral track 103 is arranged on the inner side of the mounting sleeve 102, and the guide column 202 is slidably clamped in the spiral track 103.

[0054] During use, the device can control the lifting and lowering of the rotating cylinder 201 in the installation sleeve 102. During the lifting and lowering process, the rotating cylinder 201 can be driven to rotate as a whole through the cooperation of the guide column 202 and the spiral track 103. A receiving seat 301 is rotatably provided on the rotating cylinder 201, a connecting ring 203 is provided on the rotating cylinder 201, and a clamping plate 302 is provided at the bottom of the receiving seat 301. The clamping plate 302 is rotatably clamped in the connecting ring 203, and the connecting ring 203 is evenly distributed with first balls 204 in the circumferential direction, and the first balls 204 are in contact with the clamping plate 302. That is, the rotating cylinder 201 can be controlled to rotate by pressing down the receiving seat 301, and the friction force received by the rotating cylinder 201 during the rotation process is reduced by the arrangement of the first balls 204, thereby reducing energy loss.

[0055] like Figures 1 to 3 As shown, in this embodiment, the top of the receiving seat 301 is opened, and the rotating cylinder 201 is provided with a mounting cylinder 401, and a cleaning cotton sleeve 601 is detachably provided in the mounting cylinder 401. An adhesive layer 602 is provided on the outside of the cleaning cotton sleeve 601, and the adhesive layer 602 is attached to the inside of the mounting cylinder 401.

[0056] The movement of the mechanical arm can be controlled so that the gun nozzle of the glue squeezing gun can be extended into the cleaning cotton sleeve 601 and fit against the inner wall, which makes the gun body of the glue squeezing gun abut against the receiving seat 301, and then the glue squeezing gun can be controlled to descend as a whole. During the descent, the glue squeezing gun presses down the receiving seat 301, so that the rotating cylinder 201 can be rotated as a whole. During the rotation, the rotating cylinder 201 drives the mounting cylinder 401 and the cleaning cotton sleeve 601 inside it to rotate, so the gun nozzle can be cleaned quickly. The entire cleaning process does not require manual operation, external power source, or separate control of the movement of the cleaning cotton sleeve 601, thereby improving the practicability of the cleaning device, and has a simple structure and low cost.

[0057] like Figures 2 to 6 As shown, in the present embodiment, the mounting cylinder 401 is connected to the rotating cylinder 201 through a one-way locking mechanism. When the rotating cylinder 201 rotates, the mounting cylinder 401 is driven to rotate in one direction through the one-way locking mechanism. The one-way locking mechanism includes a connecting component arranged at the bottom of the mounting cylinder 401, and the mounting cylinder 401 is fixedly connected to the rotating cylinder 201 through the connecting component when the mounting cylinder 401 is pressed down. The connecting component includes a gear ring 402 arranged at the bottom of the mounting cylinder 401, and an annular gear groove 205 is arranged in the rotating cylinder 201. There is a gap between the annular gear groove 205 and the gear ring 402. A first elastic member 404 is arranged at the bottom of the mounting cylinder 401, and the first elastic member 404 abuts against the inner bottom surface of the rotating cylinder 201.

[0058] When the glue squeezing gun is inserted into the cleaning cotton sleeve 601 and the mounting tube 401 is controlled to be pressed down, the gear ring 402 is inserted into the annular tooth groove 205, so that the mounting tube 401 and the rotating tube 201 form a whole, and then the mounting tube 401 can be driven to rotate during the rotation of the rotating tube 201. When the glue squeezing gun moves upward, the gear ring 402 can be disengaged from the annular tooth groove 205 under the action of the first elastic member 404, so as to separate the mounting tube 401 from the rotating tube 201.

[0059] like Figures 2 to 6 As shown, in this embodiment, the one-way locking mechanism also includes a ratchet 403 fixedly connected to the mounting cylinder 401, the ratchet 403 is located outside the rotating cylinder 201, and a pawl mechanism that can follow the ratchet 403 to rise and fall is provided in the mounting sleeve 102, and the ratchet 403 is one-way locked by the pawl mechanism. The pawl mechanism includes a lifting plate 501 that can be lifted and lowered and is provided in the mounting sleeve 102, and a locking pawl 502 is hinged on the lifting plate 501, and the end of the locking pawl 502 is clamped on the ratchet 403, and a second elastic member 503 is provided between the locking pawl 502 and the inner wall of the lifting plate 501, and a third elastic member 505 is provided at the bottom of the lifting plate 501, and the third elastic member 505 abuts against the inner side of the rotating cylinder 201.

[0060] When the mounting cylinder 401 is pressed down, it rotates with the rotating cylinder 201 and pushes the lifting plate 501 downward through the ratchet 403. A positioning column 504 is provided at the bottom of the lifting plate 501, and a positioning frame 104 is provided in the mounting sleeve 102. The positioning column 504 is slidably arranged in the positioning frame 104 along its axis, and the movement of the lifting plate 501 is positioned by the cooperation of the positioning column 504 and the positioning frame 104, so that it cannot rotate. During the rotation of the ratchet 403, the locking pawl 502 is always stuck on the ratchet 403 under the action of the second elastic member 503, so as to lock the ratchet 403 in one direction, and when the mounting cylinder 401 rises, the ratchet 403 is pushed up by the third elastic member 505. During the rising process, the ratchet 403 makes the gear ring 402 disengage from the annular tooth groove 205, and then pushes the rotating cylinder 201 to rise. The rotating cylinder 201 reverses when it rises. At this time, the rotation of the mounting cylinder 401 is not controlled, so that the mounting cylinder 401 rotates in one direction. Second balls 506 are evenly distributed on the lifting plate 501 in an annular direction. The second balls 506 are in contact with the bottom surface of the ratchet 403. The second balls 506 reduce the friction between the lifting plate 501 and the ratchet 403, thereby reducing energy loss.

[0061] like Figure 1 , 2 As shown in Figures 7 and 8, in the present embodiment, an extension component is further provided on the receiving seat 301, and the extension component includes an extension ring 304, a snap-in ridge 305 is provided at the bottom of the extension ring 304, a snap-in groove 303 is provided at the top of the receiving seat 301, the snap-in ridge 305 is snapped in the snap-in groove 303 and is magnetically connected thereto, and an adhesive anti-slip ring 306 is also provided at the top of the extension ring 304.

[0062] The extension ring 304 of different heights or sizes can be replaced according to different models of glue extruding guns, so that after the gun nozzle is inserted into the cleaning cotton sleeve 601, the gun body can abut against the extension ring 304, avoiding direct pressure on the gun nozzle and preventing damage to the glue extruding equipment. And through the magnetic attraction of the clamping ridge 305 and the clamping groove 303, the replacement of the extension ring 304 is faster. The anti-slip ring 306 can be set to a flexible material to prevent the receiving seat 301 from rotating as a whole, while protecting the glue extruding gun.

[0063] Specific usage and beneficial effects of the present invention:

[0064] When the device is in use, the base 101 is fixed in the working area. When the nozzle of the glue squeezing gun needs to be cleaned, the glue squeezing mechanical arm can be controlled to move so that the nozzle end of the glue squeezing gun extends into the cleaning cotton sleeve 601 and abuts against the side wall thereof, and at the same time, the cavity of the glue squeezing gun abuts against the receiving seat 301 or the receiving component above it, and then the end of the mechanical arm is controlled to move downward to push the receiving seat 301 and the rotating cylinder 201 to move downward. The rotating cylinder 201 is controlled to rotate by the component during the downward movement. The rotating cylinder 201 drives the installation cylinder 401 and the cleaning cotton sleeve 601 inside it to rotate during the rotation process, so as to quickly wipe the nozzle of the glue squeezing gun. By repeatedly pressing down the gun nozzle, the cleaning cotton sleeve 601 can be quickly controlled to rotate continuously, and the one-way locking mechanism can make the mounting tube 401 rotate only in one direction, so as to avoid the residue wiped from adhering to the gun nozzle again during the cleaning process, and the movement of the mechanical arm can be controlled to drive the gun nozzle to swing slowly to move up the position of contacting the cleaning cotton sleeve 601, so as to fully clean the gun nozzle, effectively avoid the colloid adhering to the gun nozzle and causing the diameter of the glue to fail to meet the process requirements, and prevent residual glue from adhering to the car body and affecting the appearance, and the entire cleaning process does not require manual cleaning, which effectively reduces the labor intensity and safety hazards of the staff and improves production efficiency.

It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments. On the basis of the present invention, some modifications or improvements can be made thereto, which is obvious to those skilled in the art.
