Description

Technical Field

[0001] This invention relates to the field of surface mount technology, specifically to a device that can simultaneously hot-press and weld multiple panels. Background Technology

[0002] SMT (Surface Mount Technology), also known as surface mount technology, is an electronic surface assembly technology. With the development of the SMT industry, various soldering methods have been applied to various products. Now, hot bar soldering has become a mainstream soldering method in the industry.

[0003] Existing technical solutions employ a single-machine, single-head operating mode, using a single-piece fixing fixture. A worker places the product into the fixture, presses the start button, and the machine controls the hot press head to press down, bonding the product at the welding position. After bonding, the machine lifts the press head, and the worker removes the product. This process completes the welding in a single cycle, meaning only a single piece can be bonded at a time. This low efficiency significantly increases manufacturing costs. Furthermore, existing solutions require continuous operator monitoring, leaving workers idle for most of the time and resulting in wasted manpower. Therefore, this invention provides a device capable of simultaneously hot-pressing and welding multiple panels. Summary of the Invention

The tray 711 is used as the initial carrier for receiving and loading finished panels. Its size is adapted to the full tray 722 to ensure compatibility when the tray is replaced. When the full tray 722 at the work station is filled with welded panels, the lifting mechanism 721 drives the full tray 722 to descend to the designated position. The motor 714 drives the single-layer tray moving mechanism 712 to run along the linear guide rail 713 to accurately push the empty tray 711 to the work station, replacing the full tray 722 to continue receiving finished panels delivered by the unloading and transfer assembly 73.

[0060] Specifically, the gripping suction cup assembly 731 includes a vacuum breaking component 7311, a suction pen adjustment motor 7312, and a vacuum suction cup 7313. The vacuum breaking component 7311 can quickly break the vacuum environment after gripping, allowing the vacuum suction cup 7313 to smoothly release the finished panel, avoiding panel displacement or falling due to vacuum residue, and ensuring the stability of the feeding process. The suction pen adjustment motor 7312 can precisely adjust the height and horizontal angle of the vacuum suction cup 7313 according to the size and thickness of the finished panel, ensuring that the suction cup is completely attached to the surface of the panel, improving the reliability of gripping. The vacuum suction cup 7313 can firmly adsorb the panel and avoid scratching or crushing the surface of the panel, protecting the appearance quality of the product.

[0061] Specifically, the vacuum suction cup 7313 is set in groups of six; it can press six products at the same time, and the product output increases from one piece to six pieces in one pressing cycle, which greatly improves production efficiency.

[0062] Specifically, the lower end of the frame 81 is equipped with casters with brakes, which allows the equipment to move flexibly within the workshop. When the equipment reaches the designated position, the brakes can lock the casters to ensure the equipment remains stable during operation and prevent production accuracy from being affected by accidental movement. The fluorescent lamp 83 is an LED dimmable light source that can adjust its brightness according to the ambient light, avoiding visual fatigue to the operator caused by excessively bright or dim light, further improving the comfort and accuracy of operation, and ensuring the quality of precision work.

[0066] The pressure monitoring module collects pressure data from each welding head in real time.

[0067] The visual inspection module performs online inspection of welding quality.

[0068] With the effective coordination of the timing control module, temperature closed-loop control module, pressure monitoring module, and visual inspection module, the system ensures that each workstation operates collaboratively without conflict. It accurately controls the hot pressing temperature to guarantee welding strength and consistency, monitors the pressure in real time to prevent overpressure damage to the panels or underpressure leading to weak welds, and uses visual inspection to promptly identify weld defects, panel misalignment, and other issues and trigger corresponding processing mechanisms. This comprehensively ensures the quality stability and production continuity of multi-panel hot pressing welding, significantly improves the automation and intelligence level of the equipment, and helps enterprises achieve efficient and high-quality mass production.
