Description

Technical Field

[0001] This utility model relates to the field of automotive spoiler processing technology, and in particular to an adaptive adjustment welding angle structure for an automotive spoiler welding table. Background Technology

[0002] A car spoiler is an aerodynamic device installed on the exterior of a vehicle. It is typically located at the front, rear, or sides of the car, and comes in various shapes and designs. Its main function is to reduce wind resistance and lift by altering the direction and speed of airflow around the vehicle, thereby improving driving stability and handling. It also adds a sporty touch to the vehicle's appearance. During the manufacturing process of car spoilers, welding stations are frequently used to weld the spoilers together, ensuring the strength of the connections between the various parts and meeting performance requirements.

[0003] Existing automotive spoiler welding stations typically consist of a platform, welding heads, a mechanical transmission structure, and a control system. While these stations can weld automotive spoilers of specific specifications, they lack an angle adjustment mechanism. Since the welding angles of different spoiler sizes mounted on different fixtures often differ, these stations are unsuitable for welding spoilers of various sizes. A few automotive spoiler welding stations do have an angle adjustment mechanism, but they lack an adaptive automatic adjustment structure. When welding different sizes of automotive spoilers, workers must manually adjust the angles of each welding head, resulting in low precision and significant waste of manpower and time.

[0004] Therefore, there is an urgent need to provide an adaptive welding angle adjustment structure for automotive spoiler welding stations to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an adaptive adjustment welding angle structure for an automotive spoiler welding station.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing an adaptive adjustment welding angle structure for an automotive spoiler welding table, including a welding table mechanism and a detection mechanism. The welding table mechanism is fixed with a lifting mechanism for controlling the lifting of the welding part, and the lifting mechanism is fixed with a detection mechanism for detecting the angle of the spoiler.

[0007] An adjustment mechanism is also fixed on the lifting mechanism;

[0008] A control mechanism for coordinating the operation of components is fixed on one side of the welding table mechanism.

[0009] The present invention is further configured such that: the welding table mechanism includes a table body, and support feet are fixed at the four corners of the bottom end of the table body; a limit rod is fixed on the inner side of the table body; and a welding fixture is also fixedly installed on the table body.

[0010] Through the above technical solutions, the platform can provide a work platform with a suitable height, which is convenient for people to operate, and the welding fixture can be used to fix the car spoiler. The welding fixture is detachable and replaceable.

[0011] The present invention is further configured such that: the lifting mechanism includes a cylinder fixed to the top of the platform, a lifting frame is fixed to the output end of the cylinder, limit sleeves are fixed at the four corners of the top of the lifting frame, a bearing is fixed on the lifting frame, and a limit frame is also fixed on the lifting frame.

[0012] With the above technical solution, when the cylinder extends, the lifting frame slides downward, and the limiting sleeve slides and the limiting rod are slidably connected, which effectively ensures the stability of the lifting frame when it is raised and lowered, and the bearing and the hole of the limiting frame are aligned.

[0013] The present invention is further configured such that: the detection mechanism includes a line laser fixed on the lifting frame, and the detection mechanism also includes a receiver fixed on the lifting frame, wherein multiple photoelectric sensors are arrayed on the receiver.

[0014] Through the above technical solution, the line laser can emit a line-shaped laser beam. When the laser beam shines on the spoiler workpiece to be welded, it will be reflected. The reflected line-shaped laser beam will be projected onto the receiver. The photoelectric sensors on the receiver are arranged in at least three rows, and their array direction is perpendicular to the line-shaped laser beam emitted by the line laser. When the angle of the car spoiler changes, the position of the line-shaped laser beam reflected on the receiver will also change, so that the photoelectric sensors at different positions receive the laser signal.

[0015] The present invention is further configured such that: the adjustment mechanism includes a reducer fixed on the lifting frame, a servo motor is fixed at the input end of the reducer, and a rotating shaft is fixed at the output end of the reducer.

[0016] Through the above technical solution, the servo motor can drive the shaft to rotate forward, reverse, or be fixed at a specified angle through the reducer. The reducer effectively reduces the output speed of the servo motor and increases the output torque of the servo motor.

[0017] The present invention is further configured such that: a plurality of connecting blocks are fixed on the rotating shaft, a mounting bracket is fixed at the bottom end of the connecting blocks, and a plurality of welding heads are fixedly mounted at the bottom end of the mounting bracket.

[0018] The above technical solution uses an ultrasonic welding head, which can weld and fix the components of the spoiler. When the shaft rotates, the connecting block and the mounting bracket will also rotate, thereby changing the angle of the welding head.

[0019] The present invention is further configured such that: the control mechanism includes a chassis fixed to one side of the platform, an industrial control computer is embedded in the chassis, an interactive screen is embedded in the industrial control computer, and a control panel is also fixed in the industrial control computer.

[0020] The above technical solution includes modules such as control circuits, power inductors, and heat dissipation devices inside the chassis. The industrial control computer is electrically connected to components such as cylinders, linear lasers, photoelectric sensors, servo motors, and welding heads. The industrial control computer can control the linear laser to emit a linear laser beam, calculate the angle of the spoiler workpiece based on the signal returned by the photoelectric sensor, and start the servo motor to rotate the welding head to match the workpiece angle, thus achieving adaptive adjustment of the welding angle. After the angle adjustment is completed, the industrial control computer can control the cylinder and welding head to press down to complete the welding. The operator can interact with the device through the interactive screen and control panel to adjust the welding parameters.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. By adjusting the mechanism, the welding angle of the device is adjustable, thus making the device suitable for welding workpieces of various specifications and angles, effectively improving the versatility of the device;

[0023] 2. By setting up a detection mechanism, an adjustment mechanism, and a control mechanism, this utility model enables the device to adaptively adjust the welding angle according to the angle of the workpiece, with high adjustment accuracy and reduced manpower and time waste caused by manual adjustment.

Detailed Implementation

[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0031] Please see Figures 1-5 An adaptive adjustment welding angle structure for a car spoiler welding station includes a welding station mechanism 1 and a detection mechanism 3. The welding station mechanism 1 includes a station body 101, with support feet 102 fixed at the four corners of the bottom end of the station body 101. Limiting rods 103 are fixed on the inner side of the station body 101. A welding fixture 104 is also fixedly installed on the station body 101. The station body 101 can provide a working platform with a suitable height for easy operation. The welding fixture 104 can be used to fix the car spoiler and is detachable and replaceable.

[0032] like Figure 1 , Figure 3 and Figure 4As shown, a lifting mechanism 2 for controlling the raising and lowering of the welding section is fixed on the welding table mechanism 1. The lifting mechanism 2 includes a cylinder 201 fixed to the top of the table body 101. A lifting frame 202 is fixed to the output end of the cylinder 201. Limiting sleeves 203 are fixed at the four corners of the top of the lifting frame 202. Bearings 204 and limiting frames 205 are also fixed on the lifting frame 202. When the cylinder 201 extends, the lifting frame 202 slides downward, and the limiting sleeves 203 are slidably connected to the limiting rod 103, effectively ensuring the stability of the lifting frame 202 during raising and lowering. The bearings 204 and the holes of the limiting frames 205 are aligned. A detection mechanism 3 for detecting the angle of the spoiler is fixed on the lifting mechanism 2. The detection mechanism 3 includes a cylinder 201 fixed to the top of the table body 101. The lifting frame 202 includes a linear laser 301, and the detection mechanism 3 also includes a receiver 302 fixed on the lifting frame 202. The receiver 302 has multiple photoelectric sensors 303 arranged in an array. The linear laser 301 can emit a linear laser beam. When the laser beam shines on the spoiler workpiece to be welded, it will be reflected. The reflected linear laser beam will be projected onto the receiver 302. The photoelectric sensors 303 on the receiver 302 are arranged in at least three rows, and their array direction is perpendicular to the linear laser beam emitted by the linear laser 301. When the angle of the car spoiler changes, the position of the linear laser beam reflected on the receiver 302 will also change, so that the photoelectric sensors 303 at different positions receive the laser signal.

[0033] like Figure 1 and Figure 5 As shown, an adjustment mechanism 4 is also fixed on the lifting mechanism 2. The adjustment mechanism 4 includes a reducer 401 fixed on the lifting frame 202. A servo motor 402 is fixed at the input end of the reducer 401, and a rotating shaft 403 is fixed at the output end of the reducer 401. Multiple connecting blocks 404 are fixed on the rotating shaft 403. A mounting bracket 405 is fixed at the bottom end of the connecting blocks 404. Multiple welding heads 406 are fixed at the bottom end of the mounting bracket 405. The servo motor 402 can drive the rotating shaft 403 to rotate forward, reverse, or be fixed at a specified angle through the reducer 401. The reducer 401 effectively reduces the output speed of the servo motor 402 and increases the output torque of the servo motor 402. The welding head 406 is an ultrasonic welding head 406, which can weld and fix the components of the spoiler. When the rotating shaft 403 rotates, the connecting blocks 404 and the mounting bracket 405 will also rotate, thereby changing the angle of the welding head 406.

[0034] like Figure 1As shown, a control mechanism 5 for coordinating the operation of components is fixed on one side of the welding table mechanism 1. The chassis 501 houses modules such as control circuits, power inductors, and heat dissipation devices. The control mechanism 5 includes a chassis 501 fixed to one side of the table body 101. An industrial control computer 502 is embedded in the chassis 501, and an interactive screen 503 is embedded in the industrial control computer 502. A control panel 504 is also fixed to the industrial control computer 502. The industrial control computer 502 is connected to components such as the cylinder 201, the linear laser 301, the photoelectric sensor 303, the servo motor 402, and the welding head 406. Electrically connected, the industrial control computer 502 can control the linear laser 301 to emit a linear laser beam, and then calculate the angle of the spoiler workpiece based on the signal returned by the photoelectric sensor 303, and start the servo motor 402 so that the angle of the welding head 406 is rotated to match the angle of the workpiece, realizing the adaptive adjustment of the welding angle. After the angle adjustment is completed, the industrial control computer 502 can control the cylinder 201 and the welding head 406 to press down to complete the welding. The operator can interact with the device through the interactive screen 503 and the control panel 504 to adjust the welding parameters.

[0035] When using this utility model, the operator first places the spoiler workpiece on the welding fixture 104, and then starts welding through the control mechanism 5. At this time, the detection mechanism 3 detects the angle of the workpiece, and the adjustment mechanism 4 adjusts the angle of the welding head 406 according to the detection result. After the adjustment is completed, the cylinder 201 extends, so that the welding head 406 presses down on the workpiece, thereby completing the spoiler welding operation.

[0036] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
