Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive lighting production technology, specifically a welding device for automotive lighting production and assembly. Background Technology
[0002] Welding in automotive lights can prevent moisture, dust, and other contaminants from entering the lights and affecting their illumination or damaging electronic components. Laser welding is one of the commonly used methods in automotive light production. It utilizes the high energy density of a laser beam to instantly melt and bond the contact surfaces of plastic parts.
[0003] In related technologies, a search revealed a scheme for a positioning welding device (announcement number CN221676116U) for the production and assembly of automotive headlights. The headlight is placed on the top surface of an overlapping anti-slip mat. A rotating device is used to rotate a threaded rod, causing a slider on the outer surface of the threaded rod to move to one side. The U-shaped sleeve on the outer surface of the slider is moved to the left end of the overlapping processing table, where it is fitted onto the surface of the headlight with an arc-shaped hollow extrusion soft block.
[0004] However, the above solution uses components such as arc-shaped hollow extrusion soft blocks and U-shaped sleeves to clamp the headlights, and then uses a lifter in conjunction with a laser welder to weld the headlights. Since the headlights cannot be repositioned after being clamped, and the headlights need to be welded at multiple points, it is difficult to complete the welding in one go. The headlights need to be repositioned afterward, which affects the welding efficiency of the headlights. Utility Model Content
[0005] The purpose of this invention is to provide a welding device for the production and assembly of automotive headlights, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a welding device for the production and assembly of automotive headlights, comprising a welding table, an adjuster mounted on the welding table, a placement table mounted on the adjuster, and positioning holes provided on the placement table;
[0007] Two push positioners are installed on the surface of the placement table. When the car light is placed in the positioning hole, it can assist in the positioning of the car light, making it less likely to make mistakes when placing the car light. The two push positioners on the left and right move the car light to position it, realizing the automatic positioning of the car light, which helps to improve the welding accuracy of the car light.
[0008] The lifting device is connected to the top of the welding table and is connected to a pressure plate. The lifting device controls the pressure plate to move down and press down on the vehicle headlight, ensuring that there will be no loosening during the welding process and achieving precise welding of the vehicle headlight.
[0009] The welding machine is installed on the welding table. The positioner controls the rotation of the vehicle headlight through the placement table so that it can be rotated and welded by the welding machine. It can achieve multi-directional welding and complete the welding of the vehicle headlight in one go, with high welding efficiency.
[0010] Furthermore, a receiving cavity is provided below the welding table, and the welding table is equipped with a maintenance door for the receiving cavity. The adjusting device includes an electric turntable, which is installed in the receiving cavity and passes through the welding table. The electric turntable is used to control the rotation of the headlight, which facilitates welding of various parts of the headlight.
[0011] Furthermore, a holding box is installed on the lower surface of the placement platform. The car light passes through the positioning hole and is placed in the holding box, which can provide auxiliary support and positioning for the car light, prevent the car light from becoming loose during the welding process, and prevent inaccurate welding.
[0012] Furthermore, the lifting device includes a second cylinder and a fixed frame connected to the second cylinder. The fixed frame is connected to a motor, and the pressure plate is fixedly connected to the motor. A pressure sensor is installed on the inner wall of the pressure plate. When the electric turntable controls the rotation of the vehicle light, the motor causes the pressure plate to rotate synchronously, improving the stability of the vehicle light rotation and ensuring that there will be no unexpected errors in the welding of the vehicle light.
[0013] Furthermore, the welding machine includes a robotic arm on which a laser welding machine is mounted. The pusher and positioner includes a first cylinder and a first clamping block connected to the first cylinder. The placement table has several sliding holes, and the first clamping block slides into the sliding holes. A linkage block and a second clamping block slide into the sliding holes. A linkage arm is provided between the first clamping block, the linkage block, and the second clamping block. The first clamping block and the second clamping block are equipped with protective pads. The first cylinder controls the first clamping block and the second clamping block to push and clamp the vehicle light, thereby achieving automatic positioning and clamping of the vehicle light with a high degree of automation.
[0014] Furthermore, universal balls are installed on the surfaces of the first clamping block, the linkage block, and the second clamping block to reduce the moving resistance of the first clamping block, the linkage block, and the second clamping block, and maintain a high-precision clamping state even after long-term use.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] (1) The housing of the car light is clamped by the placement platform and the pressure plate. The robotic arm flexibly controls the laser welding machine to align the housing with the position to be welded. The electric turntable controls the rotation of the placement platform to realize the rotation of the housing. The motor controls the rotation of the pressure plate to realize the circumferential welding of the housing, ensuring that the housing is welded in one go and improving the welding efficiency of the car light.
[0017] (2) The two housings to be welded of the vehicle lamp are placed in the positioning hole. The first cylinder pushes the first clamping block to move. The first clamping block drives the second clamping block to move through the linkage arm and linkage block. The first clamping block and the second clamping block push and position the two housings. The second cylinder controls the pressure plate to press the housings, so as to realize the automatic positioning and clamping of the vehicle lamp. Attached Figure Description

[0023] 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.
[0024] Example:
[0025] Please see Figure 1-4 This utility model provides a technical solution: a welding device for the production and assembly of automotive lights, including a welding table 1, an adjuster installed on the welding table, a placement table 4 installed on the adjuster, a positioning hole 13 provided on the placement table 4, the adjuster controls the rotation of the placement table 4, the two outer shells of the automotive light are spliced together and placed into the positioning hole 13 of the placement table 4, the positioning hole 13 is used to position the automotive light, and the placement accuracy is improved;
[0026] Two push positioners are installed on the surface of the placement platform 4. The car light is placed in the positioning hole 13. The two push positioners move the car light to position it. The two push positioners push and clamp the car light, which reduces the time and effort of manual adjustment and avoids welding error problems caused by shaking or misalignment.
[0027] A lifting device is connected to the top of the welding table 1. The lifting device is connected to a pressure plate 11. The lifting device controls the pressure plate 11 to move down and press down on the vehicle light. Through the precise control of the lifting device, the pressure plate 11 can be accurately moved to a predetermined position and press down on the vehicle light. This positioning accuracy helps to ensure the stability and consistency of the vehicle light during the welding process, thereby improving the welding quality.
[0028] A welding machine is installed on a welding table 1. The positioner controls the rotation of the vehicle headlights via a placement table 4 so that they can be rotated and welded by the welding machine.
[0029] In this embodiment, as Figure 1 As shown, a receiving cavity is provided below the welding table 1, and the welding table 1 is equipped with a maintenance door 2 for the receiving cavity. The wiring of the entire welding device is enclosed in the receiving cavity to ensure that the exterior is neat and tidy.
[0030] In this embodiment, as Figure 1 As shown, the positioner includes an electric turntable 3, which is installed in the receiving cavity and passes through the welding table 1 to ensure that the rotation of the placement table 4 is not affected by the welding table 1. The electric turntable 3 controls the rotation of the headlight with high precision, which facilitates 360-degree welding of the headlight.
[0031] In this embodiment, as Figure 1 As shown, a holding box 5 is installed on the lower surface of the placement platform 4. The car light passes through the positioning hole 13 and is placed in the holding box 5. When the car light is welded, placing it in the holding box 5 provides a stable support platform for the car light, keeping it stable during the welding process and preventing it from shaking or shifting, thereby improving the accuracy and efficiency of welding.
[0032] In this embodiment, as Figure 1 and Figure 4 As shown, the lifting device includes a second cylinder 9 and a fixed frame 10 connected to the second cylinder 9. The fixed frame 10 is connected to a motor 12. The pressure plate 11 is fixedly connected to the motor 12. A pressure sensor 20 is installed on the inner wall of the pressure plate 11. When the pressure plate 11 presses down on the motor 12, the pressure sensor 20 senses the pressure on the headlight, ensuring that the pressure on the headlight during welding is not too great and preventing the headlight from breaking.
[0033] In this embodiment, as Figure 1 and Figure 4As shown, the welding machine includes a robotic arm 7, on which a laser welding machine 8 is mounted. The robotic arm 7 can flexibly adjust the welding position of the laser welding machine 8 to ensure that welding can be performed on various parts of the vehicle headlights, with guaranteed welding accuracy and efficiency.
[0034] In this embodiment, as Figure 2 As shown, the push positioner includes a first cylinder 6 and a first clamping block 18 connected to the first cylinder 6. The placement platform 4 is provided with a plurality of sliding holes 14. The sliding holes 14 are inclined and the first clamping block 18 slides in contact with the sliding holes 14. The sliding holes 14 are slidably connected to a linkage block 17 and a second clamping block 15. A linkage arm 19 is provided between the first clamping block 18, the linkage block 17, and the second clamping block 15. The first clamping block 18 and the second clamping block 15 are equipped with protective pads 16 to ensure that the first clamping block 18 and the second clamping block 15 will not damage the vehicle lights.
[0035] Each push positioner is equipped with four linkage arms 19, one first clamping block 18 and two second clamping blocks 15. The first clamping block 18 and the second clamping block 15 move simultaneously to achieve clamping and positioning of the vehicle headlight.
[0036] In this embodiment, as Figure 4 As shown, universal balls 21 are installed on the surfaces of the first clamping block 18, the linkage block 17, and the second clamping block 15. The universal balls 21 are used to reduce the moving resistance of the first clamping block 18, the linkage block 17, and the second clamping block 15, and to prevent wear problems.
[0037] Specifically, in use, after the two outer shells of the car light to be welded are spliced together, they are placed on the placement platform 4. The lower outer shell is supported by the holding box 5. The first cylinder 6 pushes the first clamping block 18 to move. The first clamping block 18 drives the linkage block 17 to slide through the corresponding linkage arm 19. The linkage block 17 drives the second clamping block 15 to move through the corresponding linkage arm 19. The first clamping block 18 and the second clamping block 15 on the left and right sides move at the same time to push and position the outer shell, so that the outer shell is clamped by the first clamping block 18 and the second clamping block 15 at the same time. The second cylinder 9 controls the motor 12 and the pressure plate 11 to move down through the fixing frame 10. The pressure sensor 20 on the pressure plate 11 contacts the outer shell to sense the pressure on the outer shell and avoid excessive pressure on the outer shell.
[0038] The robotic arm 7 controls the laser welding machine 8 to align with the position on the outer shell that needs to be welded. The electric turntable 3 and motor 12 rotate to control the rotation of the placement table 4 and pressure plate 11, realizing the rotation of the outer shell and achieving 360-degree circumferential welding of the outer shell. The fixed welding of two outer shells is completed at one time, resulting in high efficiency in vehicle headlight welding.
[0039] 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.
