[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0037] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a replaceable connection, or an integral connection, it can be a mechanical connection, it can be an electrical connection, it can be a direct connection, it can be indirectly connected through an intermediate medium, and it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0038] Combination Figure 1-11 As shown, a 3D glue gun nozzle of the present application comprises: a glue nozzle 1, a glue nozzle shell 2 and a plurality of nozzles 3; a plurality of fluid channels 11 are opened circumferentially on the glue nozzle 1, each of the fluid channels 11 is not connected to each other, and the fluid channel 11 has an inlet end 111 and an outlet end 112, the inlet end 111 passes through the rear end face of the glue nozzle 1, the outlet end 112 passes through the front end face of the glue nozzle 1, the extension direction of the inlet end 111 is axial, and the extension direction of each of the outlet ends 112 forms a different angle with the axial direction; a plurality of the nozzles 3 are arranged at each of the outlet ends 112 in a one-to-one correspondence, the nozzle 3 has a glue spraying flow channel 31, the extension direction of each of the glue spraying flow channels 31 is consistent with the extension direction of the outlet end 112 correspondingly connected thereto, and the glue spraying flow channel 31 connects the outlet end 112 with the outside; the glue nozzle shell 2 is connected to the glue nozzle 1, and is used to install each of the nozzles 3 above the glue nozzle 1.

[0039] Exemplarily, the glue nozzle 1 is connected to the rotating part of the 3D glue gun by a screw, the glue supply end is connected to the inlet end 111, and the feed end is also located on the rotating part and can rotate therewith, and the driving end of the 3D glue gun is connected to the robot. Multiple fluid channels 11 form different glue discharge angles at the outlet of the glue nozzle 1, and the glue discharge amount of each fluid channel 11 does not affect each other. When in use, glue is discharged from a fluid channel 11 that has been aligned with the spraying position. The 3D glue gun is driven by a robot. Due to the complex spatial position of the joint of the vehicle body, the fluid channel 11 with the most suitable outlet angle should be selected as the glue discharge channel according to the actual spraying position, and the nozzle 3 corresponding to the glue discharge channel is aligned with the structural seam inside the vehicle body structure that needs to be glued, and the robot is adjusted so that the nozzle 3 is highly consistent with the position to be sprayed, while also ensuring that the glue discharge amount is consistent and meets the spraying requirements, and then the robot is moved while discharging glue until the spraying is completed. After finishing spraying at one place and moving to the next spraying position, in addition to selecting the nozzle 3 that best matches the angle of the spraying position, the nearest nozzle 3 can also be selected as the glue discharge nozzle 3 according to the actual situation to reduce the posture adjustment of the robot and improve work efficiency. Since the present application is provided with multiple nozzles 3 with different glue discharge angles in the circumferential direction, after completing spraying at one position, it is only necessary to rotate the rotating part to adjust the glue discharge angle or generate a simple displacement to adapt to the next position to be sprayed and start spraying, which improves the efficiency of spraying and can meet the glue coating requirements of complex body seam positions.

[0040] In some embodiments, the rear end of the nozzle shell 2 has a accommodating cavity 21, and the accommodating cavity 21 surrounds the outer periphery of the nozzle 1. The front end face of the nozzle shell 2 has a plurality of mounting surfaces 22 corresponding one-to-one to each of the nozzles 3. Any two of the mounting surfaces 22 are arranged at an angle, and a mounting hole 221 connected to the accommodating cavity 21 is provided on the mounting surface 22, and the plurality of nozzles 3 are inserted into the mounting holes 221 one-to-one.

[0041] Since the spatial position of the body seams to be sprayed is complex and the range to be sprayed is large, after one spraying position is completed, the nozzle 3 on the mounting surface 22 with the most suitable inclination angle for the next seam to be sprayed is selected for the next spraying work, which can reduce unnecessary position movement of the glue gun and improve work efficiency.

[0042] In some embodiments, the extension direction of the mounting hole 221 is consistent with the extension direction of the corresponding glue spraying channel 31, and the mounting surface 22 is perpendicular to the extension direction of the corresponding glue spraying channel 31. It is more convenient to judge whether the selected nozzle 3 is suitable for the position of the body seam. By aligning the end surface of the mounting surface 22 with the body seam position, it can ensure that the spraying angle is adapted to the position to be sprayed, and it is also convenient to arrange the nozzle 3 to adapt to the complex space in the car.

[0043] In some embodiments, the rear end periphery of the nozzle 3 has a mounting flange 32, the rear end of the mounting hole 221 is provided with a countersunk hole 222, the cross section of the countersunk hole 222 is larger than the cross section of the mounting hole 221, and the mounting flange 32 is mounted on the countersunk hole 222 and is located at the top of the outlet end 112. Exemplarily, the countersunk hole 222 is a square countersunk hole 222, and the nozzle 3 is detachably connected to the nozzle holder, which is convenient for the replacement installation of the nozzle 3.

[0044] In some embodiments, the nozzle housing 2 is connected to the nozzle 1 by bolts to fix the nozzle 3 to the nozzle 1. The nozzle 3 can be fixed between the nozzle 1 and the nozzle housing 2 by tightening the bolts, and the nozzle 3, the nozzle 1 and the nozzle housing 2 can be easily replaced by removing the bolts.

[0045] like Figure 5-11 As shown, in some embodiments, three fluid channels 11 are circumferentially opened on the nozzle 1, and the three fluid channels 11 are respectively: a first channel 113, a second channel 114, and a third channel 115; the outlet end 112 of the first channel 113 forms an angle of 0° with the axial direction, the outlet end 112 of the second channel 114 forms an angle of 45° with the axial direction, and the outlet end 112 of the third channel 115 forms an angle of 75° with the axial direction.

[0046] After many tests and inspections, when setting the three fluid channels 11, the above angles can adapt to the complex body seam space, and each mounting surface 22 occupies a certain area to facilitate the determination of the glue discharge direction in a narrow space. When one nozzle 3 completes the spraying of the corresponding seam position, the other circumferentially arranged nozzles 3 only need slight adjustments to start spraying in the surrounding complex body seam space, effectively reducing the frequency of the glue gun moving to find a suitable spraying angle, thereby meeting the gluing needs of the body under a tight production rhythm.

[0047] In some embodiments, the cross-sectional area of ​​the glue spraying channel 31 decreases from the back to the front, remains unchanged, and then gradually decreases, so as to control the glue output speed and the glue output amount, and ensure that the spraying effect of the body seam meets the requirements.

[0048] In some embodiments, the glue nozzle 1 includes a bottom plate 12 and a glue outlet seat 13, wherein a plurality of the glue outlet seats 13 are evenly distributed circumferentially above the bottom plate 12, the glue outlet seats 13 are fixedly connected to the bottom plate 12, the glue outlet seats 13 are provided with the fluid channel 11, the inlet end 111 passes through the rear end face of the bottom plate 12, and the outlet end 112 passes through the front end face of the glue outlet seat 13; the bottom plate 12 and the glue outlet seat 13 are both fixedly connected to the glue nozzle shell 2, and the nozzle 3 is installed above the glue outlet seat 13; the bottom plate 12 is provided with a bolt hole 121, and the bolt hole 121 is spaced apart from the glue outlet seat 13. Exemplarily, during installation, the bolt assembly is first used to fix the 3D glue gun glue nozzle 1 to the glue gun through the bolt hole 121, and then the glue nozzle shell 2 is connected to the glue nozzle 1, so as to better realize the modular installation of the glue nozzle 1.

[0049] In some embodiments, the 3D glue gun nozzle further includes a glue pad 4, a mounting groove 131 is provided on the front end surface of the glue outlet seat 13, and the mounting groove 131 is located at the periphery of the outlet end 112, the glue pad 4 is fixedly connected to the mounting groove 131, and the nozzle 3 is installed above the glue pad 4. The nozzle 3 is in close contact with the glue pad 4, which effectively prevents the high-pressure glue from leaking from the gap between the glue nozzle 1 and the nozzle 3 during spraying.

[0050] The present application also provides a 3D glue gun, including a gun body and the 3D glue gun nozzle, the rear end of the glue nozzle 1 is fixedly connected to the gun body, a glue supply channel is provided in the gun body, and the inlet end 111 is connected to the glue supply channel. The modular assembly of the 3D glue gun nozzle 1 and the gun body can be realized, and the various parts of the 3D glue gun are also easy to disassemble and replace. When using the 3D glue gun of the present application, the glue outlet position is distributed circumferentially, and multiple nozzles 3 form different glue outlet angles with the axial direction. When one nozzle 3 completes the spraying of the corresponding joint position, it only needs to slightly adjust the other circumferentially arranged nozzles 3 to align with the nearest body joint space to start spraying, which effectively reduces the frequency of the 3D glue gun moving to find a suitable spraying angle and meets the gluing needs of the body under a tight production rhythm.

Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the scope of protection of the claims of the present invention.
