Those skilled in the art can reasonably determine the specific meanings of the above words in the present application in combination with the specific content of the technical solution.

[0025] After the automotive rear door is connected to other components of the vehicle, glass glue needs to be applied at the connection position to achieve sealing at the joint between the automotive rear door and other components, thereby achieving the effects of waterproofing and dustproofing. The glue application device is currently mainly used for automatic glue application on the automotive rear door. The glass glue strip is heated to a molten state by the glue application device, and then the molten glass glue is sprayed onto the automotive rear door. However, the glue application operation is not a process that can be continuously performed. Therefore, there is often a long time between each glue application operation. When the glue application device is not used for a long time, the glass glue at the glue outlet is prone to curing and coagulation, which in turn affects the next glue application rhythm and speed. Currently, manual cleaning of the residual glass glue at the glue outlet of the glue application device is still adopted, and automatic removal of the residual glue cannot be achieved.

[0026] Referring to Figure 1 and Figure 2 , to achieve automatic scraping of residual structural glue, the automatic residual glue scraping device 3‎00 of the present application includes a first driving part 3‎10, a second driving part 3‎30, and a glue removing part 3‎40. Among them, the first driving part 3‎10 is detachably connected to the glue application part of the glue application device. The first driving part 3‎10 has a first driving end that can move in the first direction. The second driving part 3‎30 is fixed to the first driving end. The second driving part 3‎30 has a second driving end that can move in the second direction. The glue removing part 3‎40 is fixed to the second driving end. The glue removing part 3‎40 has two cutting knives 3‎41 that can close together. During glue removal, the first driving part 3‎10 first acts to enable the cutting knives 3‎41 to move to be flush with the glue outlet of the glue application part, then the second driving part 3‎30 acts to make the cutting knives 3‎41 approach the glue outlet, and finally the glue removing part 3‎40 is used to drive the two cutting knives 3‎41 to close together to complete the cleaning and cutting of the coagulated structural glue. Then, the cutting knives 3‎41 return to their original positions under the actions of the first driving part 3‎10 and the second driving part 3‎30, facilitating the next glue scraping operation.

[0027] Specifically, during use, when the glue applying device has not performed glue applying work for more than 30 minutes, the automatic residual glue scraping device 300 of the present application is activated. First, the first driving part 310 drives the cutting knife 341 of the glue removing part 340 to move to be flush with the glue outlet of the glue applying part. Then, the second driving part 330 drives the cutting knife 341 to approach the glue outlet. At this time, the cutting knife 341 is in an open state with the two blades facing away from each other. When the glue outlet is between the two cutting knives 341, the second driving part 330 stops operating. Then, the glue removing part 340 operates to make the two cutting knives 341 close towards each other to complete the cutting of the structural glue coagulated at the glue outlet. After the glue removal is completed, the cutting knife 341 returns to the open state with the two blades facing away from each other. Then, the second driving part 330 drives the glue removing part 340 to move to a position that does not affect the glue applying of the glue applying part. Then, the first driving part 310 returns to its original position to raise the height of the cutting knife 341 to prevent the glue removing part 340 from affecting subsequent glue applying operations. The automatic residual glue scraping device 300 of the present application can achieve the automation of glue removal without manual participation, and the installation of the automatic residual glue scraping device 300 does not require major modifications to the existing glue applying device, and has strong adaptability.

[0028] Furthermore, the first driving part 310 of the present application is preferably a first air cylinder, and a connecting plate provided on the cylinder rod of the first air cylinder forms the first driving end. Specifically, the first air cylinder is a thin air cylinder, and the thin air cylinder has at least two cylinder rods to prevent the first driving end from rotating during movement, and there is no need to additionally provide a guiding structure.

[0029] Furthermore, the second driving part 330 is a second air cylinder, and a mounting plate provided on the cylinder rod of the second air cylinder forms the second driving end. Specifically, the second air cylinder is also a thin air cylinder, and the thin air cylinder has at least two cylinder rods to prevent the second driving end from rotating during movement, and there is no need to additionally provide a guiding structure.

[0030] In the embodiment of the present application, the first direction is perpendicular to the second direction. Specifically, when the first direction is the vertical direction, the second direction is the horizontal direction; when the first direction is the horizontal direction, the second direction is the vertical direction; specifically, the first direction is vertical, horizontal or other directions that can be determined according to actual use conditions, and no specific limitation is made here.

[0031] Such as Figure 1 And Figure 2As shown in the figure, the caulking device mentioned in the embodiments of the present application includes an L-shaped bracket. A caulking part is installed at the end of the bracket. The caulking part includes a fixed seat 140, a rotating motor 210, and a caulking head 220. The rotating motor 210 is fixed to the bracket through the fixed seat 140, and the caulking head 220 is fixedly connected to the output shaft of the rotating motor 210. The angle of the caulking head 220 in the horizontal direction is adjusted by the rotating motor 210. Further, the bracket includes a vertically arranged column 110. The column 110 is made of square pipe. A horizontally arranged cross beam 120 is installed at the top of the column 110. A reinforcing angle bar 130 is arranged at the connection between the cross beam 120 and the column 110.

[0032] In some other embodiments, a waste box 400 is arranged directly below the caulking head 220. The waste box 400 is used to collect the structural residual glue cut off.

[0033] Further, as Figure 3 and Figure 4 shown in the figure, the automatic scraping device for structural glue residual glue 300 further includes a first mounting seat 311. The first driving part 310 is connected to the first mounting seat 311 by bolts. The first mounting seat 311 is connected to the caulking part by bolts. Specifically, the first driving part 310 is installed on one side of the first mounting seat 311. A docking plate is arranged on the other side of the first mounting seat 311. The docking plate is connected to the fixed seat 140 by bolts.

[0034] Further, a second mounting seat 320 is threadedly connected to the first driving end. The second driving part 330 is connected to one side of the second mounting seat 320 by bolts. There are two spaced positioning members 350 on the side of the second mounting seat 320 facing the caulking head 220. The distance between the two positioning members 350 is 0.5 - 1.5 mm larger than the maximum diameter of the caulking head 220. When the cutting knife 341 moves close to the glue outlet, the positioning members 350 move to both sides of the caulking part, and the two positioning members 350 are in contact with the caulking part. The sway of the caulking head 220 during the cutting of the residual glue is restricted by the positioning members 350 to avoid affecting incomplete cutting.

[0035] In the embodiments of the present application, the glue removing part 340 is preferably a pneumatic scissors. By introducing a positive pressure air flow, the two cutting knives 341 can be closed to achieve the cutting operation.
