Since the long side of the outer panel 200 is arc-shaped, when positioning the outer panel 200, the two first positioning blocks 101 are first used to position the lateral position of the outer panel 200, and then the second positioning block 104 is controlled to position the longitudinal position of the outer panel 200. Since the outer side surface of the outer panel 200 has a certain arc shape, the outer panel 200 is positioned horizontally. In order to increase the degree of contact between the outer panel 200 and the placing table 100, a support member is provided to lift the outer panel 200 to prevent the outer panel 200 from contacting the placing table 100, and in order to reduce the contact area between the outer panel 200 and the support member, because the larger the contact area, the greater the probability of damage, a support rod 103 is additionally provided on the support plate, and two support rods 103 are used to support the outer panel 200, so as to reduce the contact area between the outer panel 200 and the support member while ensuring the stability of the outer panel 200; the cooperation of the robot arm and the positioning component is used to realize the automated gluing operation, so as to ensure the accuracy of gluing while maintaining a high gluing efficiency.

[0037] It is worth mentioning that when the outer panel 200 is placed in place, the robotic arm 105 drives the glue coating needle 107 to move to a preset position for gluing. The trajectory movement of the robotic arm 105 and the control of the glue output of the glue storage cylinder 106 belong to the prior art and will not be elaborated here.

The fixing screw passes through the screw hole and the corresponding connecting hole 111 and is locked by a nut to fix the first positioning seat 108 on the placement table 100, and the position of the first positioning seat 108 on the placement table 100 is adjustable.

[0040] In this embodiment, two first positioning seats 108 are arranged on the placement table 100, and the first positioning cylinder 109 is arranged on the first positioning seat 108 as a driving part of the first positioning block 101, so as to realize the two first positioning blocks 101 approaching or moving away from each other; and in order to adapt to the gluing operation of the outer panels 200 of different specifications and sizes, two connecting seats 110 are symmetrically arranged on the first positioning seat 108, and two rows of connecting holes 111 evenly spaced are arranged on the placement table 100. The connecting seat 110 cooperates with the two connecting holes 111 in any column of the two rows. The fixing screw passes through the screw hole and the corresponding connecting hole 111 and is locked by a nut to fix the first positioning seat 108 to the placement table 100, and the position of the first positioning seat 108 is adjustable.

[0041] It is worth mentioning that a support plate 123 is fixedly provided on the first positioning seat 108 , and the lower end of the first positioning block 101 is against the support plate 123 ; and in order to prevent a hard collision, a flexible collision layer can be added to the outer end surfaces of the first positioning block 101 and the second positioning block 102 .

[0044] Specifically, a waist-shaped hole 115 is opened on the connecting plate 114, and a connecting block 116 is integrally arranged on the second positioning block 104. In the vertical direction, the length dimension of the second positioning block 104 is smaller than the length dimension of the connecting block 116. The fixing screw passes through the waist-shaped hole 115 and is screwed to the connecting block 116, and the screw head of the fixing screw abuts against the connecting plate 114.

[0045] In this embodiment, a second positioning seat 112 is provided on the placement table 100, and a second positioning cylinder 113 is fixedly provided on the second positioning seat 112 as a driving member of the second positioning block 104. The second positioning block 104 is abutted against the flange groove on the outer panel 200 to push the bottom of the outer panel 200 to prevent the outer panel 200 from tilting up during the pushing process, and the connecting block 116 needs to be connected and cooperated with the fixing screws, so the length dimension of the second positioning block 104 is set to be larger to ensure that there is enough connection surface.

[0046] Preferably, an outer panel monitoring sensor 117 is fixedly provided on the placement table 100 , and is used to determine whether there is an outer panel 200 on the placement table 100 before the robot arm 105 performs the gluing operation.

[0047] Further preferably, a heating sleeve is fixedly provided on the outer wall of the glue storage cylinder 106 so that the glue in the glue storage cylinder 106 is always in a constant temperature state.

[0048] Preferably, a fixing plate 118 is provided on the robot arm 105, a placement hole is opened on the fixing plate 118, a notch 119 is opened on the fixing plate 118 and is connected to the placement hole, a notch 119 is provided along the width direction of the fixing plate 118, and the two ends of the notch 119 can be close to or away from each other to fix or loosen the rubber storage cylinder 106 and the fixing plate 118, and a locking screw is provided on the fixing plate 118, and the locking screw passes through the notch 119 and is screwed to the fixing plate 118.

[0049] In this embodiment, by tightening the locking screw, the two ends of the notch 119 can be controlled to approach each other to fix the rubber storage cylinder 106. When the rubber storage cylinder 106 needs to be replaced or maintained, the locking screw can be loosened.

[0050] Further preferably, a carrying plate 120 is fixedly provided on the robot arm 105, a through hole is opened on the carrying plate 120, the carrying plate 120 is located above the fixed plate 118, at least two guide columns 122 are fixedly provided on the fixed plate 118, the upper ends of the guide columns 122 pass through the carrying plate 120 and can slide relative to the carrying plate 120, and each guide column 122 is sleeved with a spring 121, the two ends of the spring 121 respectively resist the carrying plate 120 and the fixed plate 118, and the rubber storage cylinder 106 passes through the through hole and extends into the placement hole to be fixed to the fixed plate 118.

[0051] In this embodiment, when the glue coating needle 107 is used for glue coating operation, there may be a risk of collision between the glue coating needle 107 and the outer plate 200. Once the glue coating needle 107 is collided, it is very likely to bend and deform, causing blockage in the glue discharge. Therefore, a supporting plate 120 is added to the robot arm 105, and a spring 121 is arranged between the supporting plate 120 and the fixed plate 118, so that the fixed plate 118 can be telescopically displaced relative to the supporting plate 120. When the glue coating needle 107 collides with the outer plate 200, the glue coating needle 107 can compress the spring 121 to shrink, so as to avoid damage to the glue coating needle 107 as much as possible. The guide column 122 can ensure that when the fixed plate 118 moves relative to the supporting plate 120, the moving direction will not deviate.
