[0050] To illustrate the technical content of the utility model, the purposes and effects achieved, the following will be described in conjunction with the embodiments and the accompanying drawings.

[0051] In the installation of the automobile glass, usually need to mark the glue in the specified area of the glass, and in order to avoid the overflow of glue to facilitate the staff to carry out the related operation, generally also use the foam strip in the key area to block the overflow of glue. But because the foam strip material is soft, so in the process of manual bonding, not only can't guarantee the bonding accuracy of the foam strip, but also because the foam strip is easy to twist and deform, and in the process of bonding, the printing edge area is polluted. The existing foam strip positioning and bonding tooling often sets the steel profiled groove to fix the foam strip;But only rely on the profiled groove to drive the foam strip to move to the glass surface, still can't provide enough pressure to the 3M glue on the foam strip because the foam strip is soft, and then can't ensure the bonding effect of the foam strip and the glass.

[0052] Based on this, please refer to Figs. 1-3 , a foam strip positioning and bonding tooling is provided, which comprises a workbench 1 and an upper top device 2, a fixing assembly and a profiled positioning piece 3 arranged on the workbench 1;The profiled positioning piece 3 forms a limiting area;The vertical projection of the fixed part 4 of the fixing assembly and the upper top device 2 are all located in the limiting area;The upper top device 2 has an upper top part;In the vertical direction, the plane where the upper top part is located is lower than the plane where the top of the profiled positioning piece 3 is located, and the upper top part can be moved to a position where the plane where the upper top part is located is flush with the plane where the top of the profiled positioning piece 3 is located;The upper top device 2 comprises a positioning assembly and an upper top cylinder 22;The positioning assembly has a positioning groove 21 for accommodating the foam strip;The direction of the material feeding of the upper top cylinder 22 and the direction of the slot opening of the positioning groove 21 are consistent with the orientation of the positioning surface of the profiled positioning piece 3;The material feeding part of the upper top cylinder 22 and the fixed end of the fixing assembly are oppositely arranged;In the Z-axis direction, the material feeding part of the upper top cylinder 22 penetrates the groove bottom of the positioning groove 21, and the material feeding part of the upper top cylinder 22 can reciprocate in the positioning groove 21 along the Z-axis direction.

[0053] It can be understood that the foam strip positioning and bonding tooling of the utility model can drive the foam strip to be bonded to move along the bonding position of the glass surface in the Z-axis direction while the upper top cylinder 22 is combined with the positioning groove 21, so that the foam strip to be bonded placed in the positioning groove 21 can further move relative to the positioning groove 21, that is, the foam strip can completely move out of the positioning groove 21 under the action of the upper top cylinder 22, thereby avoiding that the positioning groove 21 cannot further exert pressure on the foam strip to be bonded towards the glass surface to be assembled after being in contact with the glass surface, and ultimately leading to that the foam strip cannot be fully bonded with the glass.

[0054] In some embodiments, the top material part of the upper top cylinder 22 comprises a top material sheet 221; the upper top cylinder 22 can drive the top material sheet 221 to reciprocate in the positioning groove 21 in the direction of the Z axis; the thickness of the top material sheet 221 is adapted to the groove spacing of the positioning groove 21.

[0055] In some embodiments, the two ends of the extension direction of the positioning groove 21 are respectively provided with a foam strip limiting piece 211; the positioning groove 21 and the foam strip limiting piece 211 constitute a limiting structure. Specifically, the limiting structure is used to place the foam strip to be bonded, and the two ends of the placed foam strip respectively abut against the corresponding foam strip limiting piece 211; the groove depth of the positioning groove 21 is greater than the thickness of the foam strip to be bonded, thereby avoiding the foam strip 3M glue on the foam strip directly contacting the glass after the positioning groove 21 abuts against the glass surface, thereby affecting the related fine adjustment work of the foam strip. This design can further limit the foam strip, avoiding the tendency of the foam strip placed in the positioning groove 21 to move along the extension direction of the positioning groove 21, thereby effectively improving the subsequent bonding accuracy of the foam strip.

This design specifically modifies the component structure of the upper top device 2, thereby providing structural support for the upper top device 2 to preliminarily drive the foam strip to be bonded to move towards the glass surface to be assembled; and further requires the moving direction of the upper lifting cylinder 24 and the guide direction of the guide assembly 25, which can avoid affecting the final bonding accuracy of the foam strip due to deviation of the upper top device 2 during the lifting process, and can effectively shorten the moving distance, thereby improving the overall bonding efficiency.

[0057] In some embodiments, the support plate 23 is provided with a first waist hole 231 and a second waist hole 232; the extension direction of the first waist hole 231 is parallel to the X-axis direction; the positioning groove 21 is connected with the support plate 23 through the first waist hole 231; the extension direction of the second waist hole 232 is parallel to the Y-axis direction; the movable part of the guide assembly 25 is connected with the support plate 23 through the second waist hole 232. The design further requires the component structure of the support plate 23 and the connection relationship between the support plate 23 and the positioning groove 21 and the guide assembly 25, by setting the corresponding first waist hole 231 and the second waist hole 232 on the support plate 23, so that the staff can flexibly adjust the position of the foam strip according to the actual bonding needs, thereby ensuring that the subsequent bonding precision can meet the design requirements.

[0058] In some embodiments, the fixing assembly further comprises a support part; the fixing part 4 is connected with the workbench 1 through the support part; the support part is arranged outside the limiting area; in the Z-axis direction, the projection of the material pressing end of the fixing part 4 is located in the limiting area; when the fixing assembly presses the material, the material pressing end of the fixing part 4 and the slot of the positioning groove 21 are oppositely arranged; the workbench 1 is further provided with a suction assembly; the suction assembly is arranged in the limiting area; the suction end of the suction assembly is consistent with the slot of the positioning groove 21 in the direction. Specifically, the fixing part 4 can be any commercially available device capable of tightly pressing the material, such as a lower pressing air cylinder; the suction assembly is any commercially available device with suction effect, such as a vacuum chuck 5. The design further optimizes the component structure of the workbench 1, by setting the vacuum chuck 5 and under the suction effect of the vacuum chuck 5, the glass placed on the profile positioning piece 3 can be prevented from shaking and affecting the bonding precision of the subsequent foam strip; meanwhile, the fixing part 4 is further arranged, which can apply pressure to both ends of the glass when bonding the foam strip, preventing the upper top device 2 from damaging the glass due to applying pressure to only one side of the glass.
