Description

Technical Field

[0001] This utility model relates to the field of 3C automated testing technology, and in particular to a multi-axis linkage welding testing device. Background Technology

[0002] With the widespread application of laser welding technology in smartphone manufacturing, defects such as welding position deviation, incomplete welding, and burn-through often occur in the welded products, posing a significant risk to the subsequent assembly functions of the products. Currently, the testing equipment on the market has limited functions and can usually only achieve single-sided testing, which cannot meet the needs of multi-sided and multi-angle testing. This leads to the need to configure multiple devices on the production line, which not only increases the equipment investment cost, but also reduces the testing efficiency due to the multiple positioning and transfer of products, and there are cumulative errors. In addition, the existing equipment is difficult to adapt to the rapid switching of different product models and lacks flexibility. Therefore, there is an urgent need in this field for an automated device that can achieve multi-product, multi-sided, high-precision, and high-efficiency integrated testing. Utility Model Content

[0003] The purpose of this invention is to provide a multi-axis linkage welding inspection device to solve the problems of single inspection function, low efficiency, equipment redundancy and poor flexibility in the existing technology. This invention aims to enable a single device to simultaneously inspect the weld points and appearance of multiple products on the front, back and sides, and to achieve a high-speed, high-precision automated inspection process through multi-axis linkage control, which significantly improves inspection efficiency and equipment utilization and reduces production costs.

It can complete the detection of multiple positions within 1 second. When transferring products, the front and back tooling modules rotate at a specific angle to dock the products, and the product is transferred by the alternating adsorption of the product through the vacuum adsorption device. Not only is the tooling positioning accuracy high, but the accuracy and consistency of detection are also guaranteed. 3. Automation and Intelligence: The entire process from feeding, positioning, multi-face detection to direct release and unloading after detection is fully automated, reducing manual intervention, lowering labor costs and production errors. The vision system automatically judges whether the product is OK or NG, improving the objectivity and reliability of the detection. Attached Figure Description

[0015] The front product tooling module includes a rotatable front support and four product front toolings arranged sequentially along the rotation axis of the front support.

[0016] The back and side product tooling module includes a back support and four product back toolings arranged sequentially along the rotation axis of the back support. The bottom end of the product back tooling is mounted on the back support via a rotating shaft. The back support is also equipped with a drive motor for rotating the rotating shaft. The rotating shaft is perpendicular to the rotation axis of the back support.

[0017] The workbench serves as the installation base for the equipment, employing a robust frame structure. The front product fixture module is mounted on one side of the workbench via a Y-axis linear module. The rotation of its front support is driven by a servo motor, ensuring precise positioning. The back and side product fixture modules are installed in the same manner as the front product fixture module. Its multi-axis rotation design ensures that the product can be presented at different inspection angles. The front, back, and side image detection modules are driven by linear modules controlling the X and Z axes, ensuring smooth camera movement and accurate positioning.

[0018] The multi-axis linkage welding inspection equipment also includes a gantry frame, which spans across the front product tooling module and the back and side product tooling modules. The front photographic inspection module and the back and side photographic inspection module are arranged on both sides of the gantry frame. Both the front-facing photo detection module and the back and side-facing photo detection module include a camera module, a Z-axis lifting linear module, and an X-axis lateral linear module. The X-axis lateral linear module is mounted on the gantry and is used to drive the first mounting plate to reciprocate along the X-axis.

The vacuum receiving system ensures the reliability of product transfer in the tooling room. Safety light curtains can be installed around the equipment to ensure the safety of operators.

[0021] The working principle of this invention is as follows: After the product is manually placed on the front product fixture, the equipment is started. The front product fixture module moves to the front photographic inspection station via a Y-axis linear module, where it photographs and inspects the front of the product. After inspection, the front fixture rotates a specific angle (e.g., 90°) to mate with the back fixture module, transferring the product to the back fixture module via vacuum adsorption or other methods. Subsequently, the back fixture module moves to the back inspection station, where the back and side photographic inspection modules, under multi-axis linkage control, complete the inspection of multiple sides of the product (e.g., the back and multiple sides). Finally, the inspected products are transferred to the unloading station, where operators can determine whether the products are qualified and classify them according to the indicator lights.
