Description

Technical Field

[0001] This utility model relates to the field of vehicle lamp assembly technology, specifically a three-station glue station for vehicle lamp glue application assembly. Background Technology

[0002] During the manufacturing process of automotive headlights, components such as the LED chip are first installed into the lamp holder to form a lamp holder assembly. Then, a lens cover is fitted into the opening of the lamp holder to complete the headlight assembly. To ensure the headlight's airtightness, sealant is typically applied to the groove at the lamp holder opening of the lamp holder assembly. The lens cover is then snapped onto the lamp holder to form the headlight assembly. Next, the assembled headlight assembly is placed in a curing tower to cure the sealant, after which the headlight can be removed for the next step of airtightness testing.

[0003] In related technologies, when assembling automotive lights with adhesive, a production line-style operation is generally adopted. The automotive lights undergo surface treatment, adhesive application, screwing, and adhesive curing. These steps are completed individually at each workstation, and the automotive lights need to be transferred at each workstation. This results in low assembly efficiency, a complex production line structure, increased downtime, and difficulty in controlling the intervals between processes, which is not conducive to improving production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a three-station adhesive application station for automotive headlight assembly, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a three-station glue station for assembling automotive lights, comprising a frame, a feeding fixture on the side of the frame for placing and positioning the lamp housing, and a first robotic arm located on the side of the feeding fixture inside the frame, the first robotic arm being equipped with a gripping head, the first robotic arm using the gripping head to remove the lamp housing and place it on the lamp holder;

[0006] A three-station turntable is placed inside the frame. A third robotic arm is installed on the upper part of the inner wall of the frame. The third robotic arm is equipped with a plasma nozzle. The three-station turntable holds the lamp holder. The third robotic arm controls the plasma nozzle to perform surface treatment on the lamp housing and the base, which helps to improve the bonding strength.

[0007] The second robotic arm is installed inside the frame and located on the side of the three-station turntable. The second robotic arm is equipped with a glue dispensing head. After the glue dispensing head applies glue to the base, the lamp housing is bonded to the base.

[0008] A nailing machine is installed at the corner of the frame and located on the side of the first robotic arm. The first robotic arm delivers the assembled vehicle lights to the nailing machine and fixes them with screws.

[0009] Furthermore, a cooling tower is installed on the side of the frame, and the cooling tower has an opening corresponding to the gripping head. The first robotic arm delivers the vehicle headlight to the cooling tower, and an air conditioner is installed inside the cooling tower to quickly cure the adhesive.

[0010] Furthermore, the gripping head includes a fixed plate, on which a plurality of pneumatic grippers are mounted, and a plurality of rubber pad support seats are fixedly connected to the fixed plate. The pneumatic grippers, in conjunction with the rubber pad support seats, clamp the vehicle headlights without damaging them.

[0011] Furthermore, the three-station turntable is equipped with three positioning fixtures, which can improve the efficiency of applying adhesive to vehicle lights, make the continuous application of adhesive to vehicle lights more consistent, and reduce transfer time.

[0012] Furthermore, the pneumatic gripper includes a support rod, on which a positioning frame is mounted. A gripper is movably mounted on the positioning frame. A fixed frame is rotatably mounted on the positioning frame. A cylinder is mounted on the fixed frame. The cylinder is rotatably connected to the gripper via a Y-shaped seat. The cylinder controls the movement of the gripper to clamp the vehicle light. Multiple grippers achieve multi-point clamping of the vehicle light, resulting in high precision in transporting the vehicle light.

[0013] Furthermore, the positioning frame has guide holes on its surface, and the claw is connected to a pin located inside the guide holes, so that the claw can move and rotate, and can clamp the vehicle light more quickly.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The base is positioned and placed by three positioning fixtures of the three-station turntable. The first robotic arm uses the gripping head to take the lamp housing from the feeding fixture. The third robotic arm cleans the lamp housing and the base with the plasma nozzle. The second robotic arm controls the glue dispensing head to apply glue to the base, and the lamp housing and the base are assembled into a car light. The car light is sent to the nailing machine by the first robotic arm to be fixed with screws. This realizes continuous operation of car light surface treatment, glue application and screwing, reduces the transfer steps between stations, significantly reduces the stop time, and improves the production efficiency of car lights.

[0016] (2) A cooling tower is arranged on the side of the frame. The first robotic arm directly sends the bonded car lights into the cooling tower. The low temperature accelerates the curing of the adhesive, realizing a rapid connection between the application of adhesive and curing. The adhesive curing speed is fast, which is also conducive to improving the production efficiency of car lights.

[0017] (3) The movement of the chuck controlled by the cylinder can clamp the car light. The rubber pad support seat supports the flexible support rod of the car light. The chuck and the rubber pad support seat clamp at multiple points in coordination, resulting in high clamping accuracy. This ensures that the car light will not be damaged during transportation and improves the assembly yield of the car light. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example:

[0028] Please see Figure 1-7 This utility model provides a technical solution: a three-station glue station for automotive headlight gluing assembly, including a frame 1. The frame 1 is provided with a feeding fixture 3 on its side. The feeding fixture 3 is driven by a linear module. The headlight housing is placed on the feeding fixture 3 for positioning. A first robotic arm 5 located on the side of the feeding fixture 3 is installed inside the frame 1. The first robotic arm 5 has a five-axis structure and is equipped with a gripping head. The feeding fixture 3 cooperates with the first robotic arm 5 to realize automatic feeding and gripping of the headlight housing, ensuring accurate gripping.

[0029] The three-station turntable 2 is placed inside the frame 1. A third robotic arm 13 is installed on the upper part of the inner wall of the frame 1. The third robotic arm 13 has a five-axis structure and is equipped with a plasma nozzle 12. The three-station turntable 2 can hold three bases. The third robotic arm 13 controls the plasma nozzle 12 to clean the bonding position between the base and the lamp housing, and can flexibly perform surface treatment on the lamp housing and the base.

[0030] The second robotic arm 7 is a five-axis structure. The second robotic arm 7 is installed inside the frame 1 and located on the side of the three-station turntable 2. The second robotic arm 7 is equipped with a glue dispensing head 8. The second robotic arm 7 controls the movement of the glue dispensing head 8, which can precisely control the glue dispensing position. The glue dispensing operation is completed directly on the three-station turntable 2, avoiding multiple transfers of the base between different stations and reducing the stop time.

[0031] The nailing machine 14 is installed at the corner of the frame 1 and located on the side of the first robotic arm 5. After the lamp housing and the base are bonded together, the nailing machine 14 uses screws to reinforce the lamp housing and the base.

[0032] In this embodiment, as Figure 1 As shown, a cooling tower 4 is installed on the side of the frame 1. The cooling tower 4 has an opening corresponding to the gripping head. An air conditioner is installed inside the cooling tower 4. The air conditioner lowers the internal temperature of the cooling tower 4. The first robotic arm 5 sends the car light through the opening to the cooling tower 4 via the gripping head. The cooling tower 4 has a lamp outlet. After the glue cures, the car light is taken out from the lamp outlet and sent to the next process.

[0033] In this embodiment, as Figure 6 As shown, the gripping head includes a fixing plate 6, on which a plurality of pneumatic grippers 10 are installed to achieve multi-point clamping of the lamp housing and the vehicle lamp, ensuring that the lamp housing and the vehicle lamp are clamped stably.

[0034] In this embodiment, as Figure 6 As shown, several rubber pad support seats 11 are fixedly connected to the fixing plate 6, which can provide flexible support for the headlights, prevent marks from being left on the headlights, and improve the surface quality of the headlights.

[0035] In this embodiment, as Figure 5 As shown, the three-station turntable 2 is equipped with three positioning fixtures 9, which can hold three bases. When one base is being glued, the other bases can be placed. The glued bases can be bonded to the lamp housing, making it easy to send the lamp housing of the bonded base to the nailing machine 14.

[0036] In this embodiment, as Figure 6As shown, the pneumatic gripper 10 includes a support rod 15, on which a positioning frame 18 is mounted. A gripper 19 is movably mounted on the positioning frame 18. A fixing frame 16 is rotatably mounted on the positioning frame 18. A cylinder 17 is mounted on the fixing frame 16. The cylinder 17 is rotatably connected to the gripper 19 via a Y-shaped seat 20. A guide hole 21 is provided on the surface of the positioning frame 18. A pin 22 located inside the guide hole 21 is connected to the gripper 19. There are two guide holes 21, one straight and one bent, which can control the rotation of the gripper 19. When the cylinder 17 pushes the gripper 19 to move, the gripper rotates to avoid the lamp housing and vehicle headlight, making it easy to quickly grab the lamp housing and vehicle headlight.

[0037] Specifically, during use, the base is placed on the positioning fixture 9 of the three-station turntable 2, the lamp housing is placed on the feeding fixture 3, the third robotic arm 13 controls the plasma nozzle 12 to clean the base and the lamp housing, the three-station turntable 2 controls the base to move next to the glue dispensing head 8, the second robotic arm 7 controls the glue dispensing head 8 to apply glue to the base, and at this time the plasma nozzle 12 cleans the next base.

[0038] The three-station turntable 2 continues to rotate, sending the glued base to the side of the first robotic arm 5. The first robotic arm 5 drives the claw 19 to contact the lamp housing through the fixing plate 6. The cylinder 17 controls the movement of the claw 19 to clamp the lamp housing. The first robotic arm 5 sends the lamp housing to the base. At this time, the next lamp housing is placed on the feeding fixture 3. The base and the lamp housing are bonded together. At this time, the base and the lamp housing form a car light.

[0039] After the base and the lamp housing are bonded together, the first robotic arm 5 controls the lamp to move to the nailing machine 14. The nailing machine 14 screws the screws to the lamp, thus reinforcing the lamp. Then, the first robotic arm 5 sends the lamp to the cooling tower 4 to cure the adhesive, thus completing the adhesive application process for the lamp.

[0040] 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.
