Description

Technical Field

[0001] This utility model relates to the field of welding robots, and in particular to an automated welding robot for automobile assembly. Background Technology

[0002] Welding is a critical process in automobile manufacturing. Traditional welding methods typically rely on manual operation, resulting in low efficiency and inconsistent quality. With the development of automation technology, automated welding robots have gradually become important equipment in automobile manufacturing.

[0003] However, after prolonged operation, the welding head of existing welding robots generates high temperatures, which can easily damage the cleaning device if cleaned directly. If the welding head is allowed to cool naturally before cleaning, the debris generated during processing can easily adhere to the outside of the welding head as it cools down.

[0004] Therefore, it is necessary to propose an automated welding robot for automobile assembly to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an automated welding robot for automobile assembly, in order to solve the problem that, after working for a long time, the welding head of the existing welding robot generates high temperatures, and if it is cleaned directly, it is easy to damage the cleaning device. If the welding head is allowed to cool naturally before cleaning, the debris generated during processing is easy to stick to the outside of the welding head as it cools down.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automated welding robot for automobile assembly, comprising:

[0007] The moving mechanism is mounted on the support frame;

[0008] A welding head, wherein a rotating sleeve is rotatably connected to the bottom end of the welding head, and the welding head is mounted on a moving mechanism;

[0009] A cooling mechanism is provided on one side of the welding head, and the cooling mechanism is used to cool and clean the outside of the welding head;

[0010] The cooling mechanism includes a fixing block, on which a V-shaped groove corresponding to the shape of the welding head is formed;

[0011] The V-groove is divided into two regions along its length. Each region contains a cleaning layer for friction with the welding head and pores for cooling the welding head.

[0012] Preferably, the V-shaped opening of the V-groove is oriented towards the welding head, and a rotating plate is hinged to the side of the V-groove facing the welding head;

[0013] Sandpaper is fixed to the top of the rotating plate.

[0014] Preferably, a cooling fan is fixed to the outside of the support frame, a cavity is opened inside the fixing block, and an air pipe is connected between the air outlet of the cooling fan and the cavity.

[0015] Preferably, the moving mechanism includes two first slide rails, each of which has a movable frame slidably fitted at its top end, and a crossbar is fixed between the two movable frames.

[0016] The crossbeam is slidably mounted with a connecting frame, a second slide rail is fixed on the connecting frame, a fixed frame is slidably fitted on the second slide rail, a drive motor is fixed on the fixed frame, a drive shaft at the bottom of the drive motor extends out of the fixed frame, and a connecting arm is fixed at the bottom of the extended end of the drive shaft, and the welding head is fixed to one end of the connecting arm.

[0017] Preferably, both the second slide rail and the first slide rail are electric slide rails.

[0018] Preferably, the fixing block is fixed between the two sides inside the support frame.

[0019] Preferably, a processing channel is provided at the center of the top of the support frame.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1. In the actual operation of this utility model, in the initial state, the rotating plate is perpendicular to the ground. When the welding head is inserted into the V-groove, the connecting frame can be controlled to move left and right on the cross frame, so that the outer side of the welding head moves left and right in the V-groove. In the initial position, the cooling fan is started, and the cooling air is discharged from the air hole to cool the outer side of the welding head first. Excess debris will also be blown off, and the outer side of the welding head will rub against the sandpaper to remove the adhering high-temperature debris.

[0022] As the welding head continues to move, the outer side of the welding head comes into contact with the sandpaper and cleaning layer, removing debris and dirt that are difficult to blow off through friction. When not in use, the welding head extends into the V-groove, and the V-groove and rotating plate protect the outer side of the welding head to prevent direct cleaning and thus avoid melting of the cleaning device.

[0023] 2. Since the rotating sleeve is rotatably connected to the welding head, the friction force will cause the rotating sleeve to rotate when friction occurs, thereby cleaning the entire outer ring of the rotating sleeve. During welding, the laser will be emitted from the inner ring of the rotating sleeve, which plays a protective role. The entire device is easy to operate and achieves automated welding through electric control, reducing manual intervention. At the same time, the design of the cooling mechanism and cleaning mechanism makes maintenance more convenient and reduces maintenance costs. Attached Figure Description

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.

[0031] This utility model provides, for example Figure 1 - Figure 4 The automated welding robot for automotive assembly shown includes:

[0032] The moving mechanism is mounted on the support frame 1;

[0033] The welding head 12 has a rotating sleeve 19 rotatably connected to its bottom end, and the welding head 12 is mounted on a moving mechanism that can drive the welding head 12 to adjust its position.

[0034] Specifically, the moving mechanism includes two first slide rails 4, each of which has a sliding frame 7 slidably fitted at its top end, and a crossbar 5 fixed between the two sliding frames 7.

[0036] When the drive motor 10 is started, it can drive the connecting arm 11 and the welding head 12 to rotate, making it easy to adjust the position of the welding head 12. The electric second slide rail 8 and the first slide rail 4 can drive the welding head 12 to move back and forth and up and down, adjusting its position and height, enabling precise movement and positioning of the welding head 12, and improving welding efficiency and accuracy.

[0037] The cooling mechanism is located on one side of the welding head 12 and is used to cool and clean the outside of the welding head 12. The cooling mechanism includes a fixing block 3, on which a V-shaped groove 13 corresponding to the shape of the welding head 12 is provided.

[0038] The V-groove 13 is divided into two regions along its length. Each region is provided with a cleaning layer 18 that rubs against the welding head 12 and a pore 14 that cools the welding head 12.

[0039] The V-shaped opening of the V-groove 13 is set towards the welding head 12, and a rotating plate 16 is hinged to the side of the V-groove 13 facing the welding head 12. The rotating plate 16 is connected to the V-groove 13 through a rotating shaft, and a torsion spring is provided on the rotating shaft. Sandpaper 17 is fixed to the top of the rotating plate 16.

[0040] A cooling fan 2 is fixed on the outside of the support frame 1, and a cavity is opened inside the fixing block 3. An air pipe 15 is connected between the air outlet of the cooling fan 2 and the cavity.

[0041] The fixing block 3 is fixed between the two sides inside the support frame 1.

During welding, the laser is emitted from the inner ring of the rotating sleeve 19, providing protection. The entire device is easy to operate, achieving automated welding through electric control and reducing manual intervention. Simultaneously, the design of the cooling and cleaning mechanisms makes maintenance more convenient and reduces maintenance costs.
