Description

Technical Field

[0001] The invention relates to the technical field of gluing and pressing of automobile headlights, and in particular to a through-type automobile headlight shell gluing and pressing device and a method thereof. Background Art

[0002] Car headlights are one of the most important parts of a car. They have multiple functions and features. They provide drivers with a clear view of the road at night or in low visibility conditions to ensure driving safety. For example, on rural roads without street lights, bright headlights allow drivers to promptly detect obstacles and pedestrians ahead. They can convey the vehicle's driving intentions, such as turning and overtaking, to other road users through flashing or unique light patterns. Uniquely designed headlights can enhance the overall appearance of the car and increase its recognition and attractiveness.

[0003] After searching, the Chinese patent authorization number CN210733327U discloses a gluing and pressing device for a car headlight shell, including a workbench, a built-in rod and a CNC gluing robot. A top plate is arranged above the workbench, the screw rod is connected to the positioning plate through a positioning groove, the built-in rod is symmetrically arranged inside the two sides of the positioning plate, the CNC gluing robot is installed in the middle position of the upper surface of the workbench, an inner cavity is opened in the middle position of the bottom surface of the workbench, limiting rods are symmetrically welded inside the two sides of the positioning plate, a bottom fixing rod is installed on the inner lower surface of the workbench, and the slide rails are symmetrically installed on the outer sides of the support block. The above patent has the following deficiencies: when applying glue and pressing the existing automobile headlights, the staff usually places one of the lamp shells into the mold, applies glue, and then places the other lamp shell on the glued lamp shell for pressing. However, during the pressing process of the existing automobile headlights on the equipment, the function of fixing the lamp shell mold is not available. As a result, when the automobile headlights are pressed, it is easy to offset, causing the two lamp shells to be misaligned when pressed, resulting in deviations, reducing the quality of automobile headlight production, and even causing deformation or damage to the material; and after the pressing is completed, it needs to be plastic-sealed. The traditional method generally involves manually removing the pressed headlight from the mold and then plastic-sealing it. During this process, it is easy for dust to stick to the surface of the headlight, resulting in poor plastic sealing effect in the later stage, and causing many bubbles to be generated during the plastic sealing process, greatly reducing the production efficiency of automobile headlights.

A worker first places one of the automobile headlight shells to be coated with glue in the second headlight mold (6), and then a gluing robot (4) performs a gluing operation on it. Then, another automobile headlight shell is buckled onto the glued headlight, and then the cylinder (3) is started to drive the first headlight mold (5) to move downward; S2. The first headlight mold (5) and the second headlight mold (6) are then pressed downward after contacting each other, so that the first headlight mold (5) and the second headlight mold (6) drive the lower pressing plate (7) to slide downward, thereby driving the rectangular plate (8) to slide up and down on the fixing rod (9), pulling the two connecting rods (10) to drive the two sliders (11) to shrink toward the surface of the workbench (2), thereby driving the two positioning plates (12) to fit and clamp the first headlight mold (5) and the second headlight mold (6) to position, so that the automobile headlight remains fixed during the downward pressing process to prevent deviation during the pressing process. After the pressing is completed, the cylinder (3) drives the first headlight mold (5) to reset upward.
