[0028] Embodiment 1

[0029] See also Figure 1 On the one hand, when the glue nozzle 100 is directly installed on the glue gun body 200, due to the uncontrollability of the installation angle, the glue outlet position error of the glue nozzle 100 is large, resulting in a collision between the glue nozzle 100 and the vehicle body, and the gluing effect is not good. On the other hand, during the gluing process, the glue nozzle 100 is applied on the vehicle body at an extremely high speed, and the glue nozzle 100 is prone to loosening, resulting in a change in the glue outlet position and reducing the gluing accuracy.

[0030] This embodiment is suitable for positioning the angle between the glue gun body 200 and the glue nozzle 100 (i.e., the above-mentioned installation angle), maintaining the uniformity of the glue discharge position, avoiding interference between the glue nozzle 100 and the vehicle body, and improving the gluing effect, wherein, in the glue discharge direction, the diameter of the glue nozzle 100 is continuously reduced, that is, the end of the glue nozzle 100 close to the glue gun body 200 has the largest outer diameter.

[0031] See also Figure 2 This embodiment provides a positioning device 300 . Specifically, the positioning device 300 includes a mounting seat 310 and a first positioning member 320 and a second positioning member 330 mounted on the mounting seat 310 .

[0032] The mounting base 310 includes a first base body 311 and a second base body 312, and the first base body 311 is fixedly connected to the second base body 312. Specifically, the first base body 311 and the second base body 312 are fixedly connected by bolts (not shown in the figure).

[0033] The first base body 311 includes a first support portion 3110, a second support portion 3111 and a third support portion 3112, wherein the second support portion 3111 is vertically adjacent to the first support portion 3110 and the third support portion 3112. The first support portion 3110 is block-shaped, the second support portion 3111 is a square tube structure, and the third support portion 3112 is also block-shaped. To improve the stability of the first base body 311, in this embodiment, the cross-sectional area of ​​the first support portion 3110 is set to be larger than the cross-sectional area of ​​the third support portion 3112.

[0034] When preparing the first seat body 311, the first support portion 3110 is placed on the work surface, the second support portion 3111 is welded to the first support portion 3110, and then the third support portion 3112 is welded to the second support portion 3111. Since the first seat body 311 is only used as a support, the precision requirement for the first seat body 311 is relatively low, thereby reducing the preparation cost while ensuring the stability of the support.

[0035] Furthermore, in this embodiment, a plurality of circular mounting holes are provided on the first supporting portion 3110 . When in use, bolts are passed through the circular mounting holes and locked on the work surface, thereby fixing the position of the positioning device 300 and preventing the positioning device 300 from moving or tipping over.

[0036] The second base body 312 is fixedly connected to the third support portion 3112. Specifically, the second base body 312 includes a first support portion 3121 and a second support portion 3122. The first support portion 3121 is fixedly connected to the third support portion 3112 of the first base body 311. The second support portion 3122 is vertically adjacent to the first support portion 3121. The first positioning member 320 and the second positioning member 330 are installed on the second support portion 3122 along the first direction.

[0037] Similar to the first base body 311 , when preparing the second base body 312 , the first support portion 3121 is placed on a work surface, and then the second support portion 3122 is welded to the first support portion 3121 .

[0038] However, since the second seat body 312 serves as a mounting seat body for the first positioning member 320 and the second positioning member 330 described later, at this time, the second seat body 312 needs to be finely processed to improve the positioning accuracy.

[0039] This embodiment uses the mounting seat 310 as the basis of the positioning device 300 to facilitate the movement of the mounting seat 310. This embodiment also splits the mounting seat 310 into a rough-processed first seat body 311 and a fine-processed second seat body 312, which reduces the preparation cost and technical difficulty and meets the positioning requirements.

[0040] The first positioning member 320 is mounted on the second base 312. Specifically, the first positioning member 320 is welded to an end of the second support portion 3122 away from the first support portion 3121. In this embodiment, the first positioning member 320 may be a plate-shaped structure, and the edge of the first positioning member 320 may be flush with the surface of the second support portion 3122. In this way, after the first positioning member 320 is welded, the verticality of the first positioning member 320 may be detected by a tool such as a square.

[0041] See also Figure 2 , Figure 3 and Figure 4 The first positioning member 320 is provided with a positioning hole 321, the positioning hole 321 has a preset hole depth, and the hole diameter of the positioning hole 321 matches the maximum outer diameter of the nozzle 100. In this embodiment, the positioning hole 321 and the maximum outer diameter of the nozzle 100 can be set to match with a preset dimensional tolerance, so that the nozzle 100 can smoothly pass through the positioning hole 321 without deflection.

[0042] In this embodiment, the positioning of the glue nozzle 100 is achieved through the positioning hole 321. If the glue nozzle 100 changes its glue outlet position due to installation errors or looseness, the glue nozzle 100 will be deflected and unable to pass through the positioning hole 321. At this time, it is necessary to adjust the relative position of the glue nozzle 100 and the glue gun body 200 until the glue nozzle 100 can smoothly pass through the positioning hole 321, indicating that the glue outlet position is the preset position.

[0043] The second positioning member 330 is installed on the second base 312 . The second positioning member 330 and the first positioning member 320 are arranged in a first direction with spacing therebetween. The first direction is the thickness direction of the first positioning member 320 . In the first direction, the distance between the first positioning member 320 and the second positioning member 330 is equal to the length of the nozzle 100 .

[0044] In this embodiment, the length of the nozzle 100 is corrected and adjusted by the cooperation between the second positioning member 330 and the first positioning member 320 .

[0045] The second positioning member 330 includes a connecting portion 331 and a positioning portion 332 that are fixedly connected to each other. In this embodiment, the connecting portion 331 and the positioning portion 332 may be arranged at a right angle.

[0046] The positioning portion 332 is arranged corresponding to the positioning hole 321. After the nozzle 100 passes through the positioning hole 321, the glue inlet end of the nozzle 100 is located in the positioning hole 321, and the glue outlet end is against the positioning portion 332, that is, the two ends of the nozzle 100 are respectively on the first positioning member 320 and the second positioning member 330, and the distance between the first positioning member 320 and the second positioning member 330 is the length of the nozzle 100.

[0047] The connecting portion 331 is fixedly connected to the mounting seat 310. In order to achieve the fixed connection between the connecting portion 331 and the mounting seat 310, in this embodiment, the positioning device 300 further includes a bolt (not shown in the figure), the connecting portion 331 is provided with a strip-shaped mounting hole 3311, the length direction of the strip-shaped mounting hole 3311 is arranged parallel to the first direction, the mounting seat 310 is provided with a circular through hole (not shown in the figure), the bolt is passed through the strip-shaped mounting hole 3311 and the through hole, and the diameter of the bolt is adapted to the aperture of the through hole.

[0048] This embodiment realizes height adjustment of the second positioning member 330 by setting the strip mounting hole 3311, thereby adjusting the distance between the second positioning member 330 and the first positioning member 320, and is suitable for nozzles 100 of different lengths, thereby expanding the application scope of this embodiment and having adaptability.

[0049] Embodiment 2

[0050] See also Figure 3 and Figure 4 Based on the first embodiment, this embodiment provides a glue coating device, which includes a glue gun body 200, a glue nozzle 100 and a positioning device 300 of the first embodiment. The glue gun body 200 and the glue nozzle 100 are arranged at an angle, and the glue nozzle 100 is inserted into the positioning device 300.

[0051] The glue coating device also includes a first connecting member 340, a second connecting member 350 and a third connecting member 360 which are threadedly connected in sequence. The first connecting member 340 is threadedly connected to the glue gun body 200, and the third connecting member 360 is threadedly connected to the glue nozzle 100, and the third connecting member 360 is arranged in a curved shape.

[0052] In this embodiment, one end of the glue gun body 200 is provided with an external thread, one end of the first connecting piece 340 is provided with an internal thread that cooperates with the external thread of the glue gun body 200, and the other end is provided with an external thread, the first end of the second connecting piece 350 is provided with an internal thread that cooperates with the first connecting piece 340, and the second end is also provided with an internal thread, one end of the third connecting piece 360 ​​is provided with an external thread that cooperates with the internal thread of the second end, and the other end is provided with an external thread, and the glue nozzle 100 is threadedly connected to the third connecting piece 360.

[0053] It is understandable that, since the third connecting member 360 is designed to be curved, the glue nozzle 100 and the glue gun body 200 have an angle, thereby avoiding interference between the glue nozzle 100 and the vehicle body and improving the gluing effect.

[0054] Please refer to Figure 2 , Figure 3 and Figure 4If the glue nozzle 100 is deflected and cannot pass through the positioning hole 321, it is necessary to rotate the second connecting member 350 to adjust the relative position of the glue nozzle 100 and the glue gun body 200, ensure the uniformity of the glue outlet position, improve the glue coating accuracy, and quickly resume the glue coating work.

[0055] Furthermore, the gluing equipment also includes a manipulator, which is fixedly connected to the glue gun body 200 and controls the movement of the glue gun body 200, thereby realizing the automated gluing process of the gluing equipment, improving the level of gluing automation, ensuring product quality, and reducing labor costs.

[0056] In this embodiment, the positioning device 300 is used to position the glue outlet position of the glue nozzle 100 to ensure that the glue nozzle 100 is located at a preset position, thereby greatly improving the applicability of special glue coating positions in automated glue coating and the automated glue coating accuracy.

[0057] Based on the above content, the use principle of the glue coating equipment is further explained in this embodiment as follows:

[0058] S100. The first connecting member 340, the second connecting member 350 and the third connecting member 360 are threadedly connected in sequence;

[0062] S500. Start the manipulator according to the preset conditions, so that the manipulator drives the nozzle 100 to move;

[0063] S600. If the nozzle 100 can pass through the positioning hole 321 without deflection, and the nozzle 100 abuts against the second positioning member 330, the positioning is completed, otherwise proceed to the next step;

[0064] S700. If the glue nozzle 100 is deflected and cannot pass through the positioning hole 321, rotate the second connecting member 350 to adjust the angle between the glue nozzle 100 and the glue gun body 200 until the glue nozzle 100 can pass through the positioning hole 321 without deflection and the glue nozzle 100 abuts against the second positioning member 330.

[0065] It is understandable that the steps of the above-mentioned usage principle are merely exemplary and do not limit the installation sequence of the glue coating equipment. For example, the sequence between S100 and S400 can be adjusted according to actual conditions.
