Description

Technical Field

[0001] This utility model relates to the technical field of adhesive coating and assembly equipment, specifically to adhesive coating and pressing equipment used in automobile production. Background Technology

[0002] Automobile door panels and hoods are mostly composed of inner and outer panels. The outer panel is made of sheet metal, while the inner panel is mostly made of plastic. Connections between the outer and inner panels include riveting, screwing, and bonding. Riveting is suitable for connecting thicker sheet metal, but the arrangement and number of rivets need to be carefully designed. Bolting, while easy to disassemble and repair, increases vehicle weight and cost. Adhesive bonding, as a non-destructive bonding method, is widely used in car door manufacturing. Adhesive bonding offers advantages such as ease of operation, low cost, and strong adaptability, enabling fast and efficient connections. Existing adhesive application and pressing equipment requires workers to move materials between the adhesive application and pressing processes, resulting in low production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide an adhesive coating and pressing equipment for automobile production, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an adhesive coating and pressing equipment for automobile production, comprising an industrial robot and an adhesive applicator, a door panel pressing mold, an engine hood pressing mold, and an outer panel loading station arranged around the industrial robot. Two door panel pressing molds are provided, one for pressing the left and one for pressing the right door. The engine hood pressing mold has the same structural composition as the door panel pressing mold. The door panel pressing mold includes an upper door panel mold and a lower door panel mold. The upper door panel mold includes a rectangular upper template. Several support blocks are fixedly installed on the lower side of the upper template. A vacuum suction cup a is embedded and installed. Several support blocks form an upper mold cavity for adsorbing the outer panel of the door on the lower side. The lower mold of the door panel includes a lower template. A horizontal support plate is fixedly installed on the upper side of the lower template by multiple columns. Several heating blocks are fixedly installed on the upper surface of the support plate. The heating blocks have a U-shaped groove in the middle. The upper ends of several heating blocks form a lower mold cavity for adsorbing the inner panel of the door. The heating blocks have an air collection chamber inside. The bottom of the groove has an exhaust hole communicating with the air collection chamber. Several vacuum suction cups b are installed on the upper side of the support plate.

[0005] Preferably, a quick-change disc is installed on the upper side of the door panel mold for rapid docking with the end effector of an industrial robot.

[0006] Preferably, two sets of symmetrical hooks are installed on the lower side of the upper template. The hooks are L-shaped rod structures. Two sets of symmetrical clamping cylinders are installed on the upper side of the lower template. The hooks and clamping cylinders are engaged and locked together after the mold is closed.

[0007] Compared with existing technologies, the advantages of this invention are as follows: This invention includes three pressing stations and one outer panel loading station. An industrial robot is located in the middle of the four stations. After docking with the upper mold, the industrial robot picks up the corresponding outer panel at the outer panel loading station, then moves the outer panel to the glue applicator for gluing, and then transfers it to the corresponding lower mold for heating and pressure holding. The door panel pressing mold and the hood pressing mold operate at different times, and one worker is responsible for loading and unloading, improving production efficiency.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Please see Figure 1-5This utility model provides a technical solution: an adhesive coating and pressing equipment for automobile production, including an industrial robot 1 and an adhesive applicator 2, a door panel pressing mold 3, an engine hood pressing mold 4, and an outer panel loading station 5 arranged around the industrial robot 1. Both the door outer panel and the engine hood outer panel are loaded at the loading station 5. Two door panel pressing molds 3 are provided, one for pressing the left and one for the right doors. The engine hood pressing mold 4 has the same structural composition as the door panel pressing mold 3 (the main difference is in the shape of the mold cavity). The door panel pressing mold 3 includes an upper door panel mold 31 and a lower door panel mold 32. A quick-change disc is installed on the upper side of the upper door panel mold 31 for rapid docking with the end effector of the industrial robot 1 (a six-axis robot). The lower door panel mold 32 is fixedly mounted on a base.

[0016] The upper mold 31 of the door panel includes a rectangular upper mold plate 311. Several support blocks 312 are fixedly installed on the lower side of the upper mold plate 311. Vacuum suction cups a313 are embedded in the support blocks 312. The support blocks 312 form an upper mold cavity for adsorbing the outer door panel on the lower side. The lower mold 32 of the door panel includes a lower mold plate 321. A horizontal support plate 322 is fixedly installed on the upper side of the lower mold plate 321 by several columns. Several heating blocks 323 are fixedly installed on the upper surface of the support plate 322. The heating blocks 323 have a U-shaped groove in the middle. The upper ends of the heating blocks 323 form a lower mold cavity for adsorbing the inner door panel. The heating blocks 323 have an air collection chamber inside. The bottom of the groove has an exhaust hole 326 communicating with the air collection chamber. The air collection chamber is connected to a hot air pipe. After the mold is closed, hot air is blown to quickly dry the adhesive. Several vacuum suction cups b325 are installed on the upper side of the support plate 322. Two sets of symmetrical hooks 314 are installed on the lower side of the upper template 311. The hooks 314 are L-shaped rod structures. Two sets of symmetrical clamping cylinders 324 are installed on the upper side of the lower template 321. The hooks 314 and clamping cylinders 324 are connected and locked after the mold is closed.

[0017] Working principle: The inner door panel and the inner hood panel are manually loaded into the corresponding lower molds. The outer door panel and the outer hood panel are loaded into the loading station 5. The end of the arm of the industrial robot 1 docks with the upper mold of the door panel pressing mold 3 or the hood pressing mold 4, and grabs the upper mold to the outer panel loading station 5. Then, the worker places the corresponding outer panel onto the upper mold. The upper mold grabs the outer panel to the glue applicator 2 for glue application, and then moves it to the corresponding lower mold for pressing. During heating and pressure holding, the industrial robot 1 separates from the upper mold to proceed to the next process.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
