Gantry Multi-Point Welding Machine

▷ Application Industry: Intelligent Warehousing & Logistics Equipment

▷ Welding Workpiece: Galvanized Sheet Shelf Reinforcement Ribs

Project Overview

In this case, PDKJ customized a gantry multi-point welding machine according to the customer's product characteristics and welding requirements. The shelf reinforcement rib gantry welding machine was successfully delivered to an East China warehousing equipment manufacturer and has been put into stable mass production.

The equipment effectively solves multiple production challenges, including welding efficiency, quality consistency, and flexible production, providing reliable support for the customer's intelligent warehousing equipment manufacturing.

I. Project Background

Customer Profile

The customer is a high-tech logistics equipment manufacturer located in East China, specializing in the R&D, production, and manufacturing of intelligent storage racks, automated warehouse components, and metal structures for material handling systems.

The company owns dozens of patents related to storage equipment structures and has import and export qualifications. Its products are widely used in factory warehouses, automated three-dimensional warehouses, logistics sorting systems, and other application scenarios.

Project Background

The customer's main mass-produced product is a 1200×1200mm galvanized load-bearing shelf panel.

To improve the load capacity of the shelf panels and prevent deformation under long-term loads, multiple reinforcement ribs with a width of 200mm need to be welded inside each panel.

Due to the large number of welding points and the requirement for simultaneous multi-point welding on one side, the existing traditional single-point spot welding equipment could no longer meet the production capacity requirements. The welding process had become the biggest bottleneck restricting the production line efficiency.

II. Customer Welding Challenges

Before designing the solution, PDKJ engineers conducted a detailed analysis of the customer's products and production process.

1. Limited Efficiency of Traditional Welding Process

Traditional single-head spot welding machines can only weld one point at a time.

A single shelf panel requires dozens of welding points, resulting in repeated material repositioning, multiple positioning operations, and long welding cycles due to manual loading, unloading, and step-by-step welding.

2. Need for Both Welding Quality and Stability for Galvanized Sheets

The welding material is 1.2mm galvanized sheet metal.

The welding process must ensure strong and reliable welding points while minimizing welding fluctuations, which requires higher equipment control accuracy and stability.

3. Fixed Welding Fixtures and Difficult Product Changeover

The customer produces shelf panels and reinforcement ribs in multiple specifications, with different welding distances between products.

Traditional fixed welding heads require complete fixture replacement when changing products. Each adjustment and debugging process takes more than 30 minutes, making it difficult to support flexible multi-product production and resulting in low equipment utilization.

III. PDKJ Welding Machine Solution Highlights

Based on the customer's actual requirements, PDKJ developed a customized Gantry Multi-Point Welding Machine for Shelf Reinforcement Ribs.

The machine adopts a gantry structure design combined with multiple welding heads working simultaneously, perfectly meeting the customer's demand for high-speed reinforcement rib welding.

Simple and Efficient Operating Process:

The equipment adopts a manual loading system combined with automatic positioning and welding:

✔ Place reinforcement ribs
✔ Position shelf panel
✔ Pneumatic cylinder clamps and fixes the workpiece
✔ Welding heads complete welding sequentially
✔ Move to the next welding position
✔ Remove the finished workpiece after all welding operations are completed

The entire welding process is smooth and easy for operators to learn and operate.

 Core Advantages of the Equipment 

1. Multiple Welding Heads Work Simultaneously, Greatly Increasing Production Capacity

The equipment is equipped with 13 welding heads, enabling multi-point simultaneous pressing and welding.

Each welding point requires only 0.5 seconds welding time.

Combined with standardized positioning fixtures, the entire process of panel placement, reinforcement rib positioning, and material removal is standardized.

For standard workpieces with two reinforcement ribs, the actual production cycle is only 25 seconds per piece.

Compared with traditional welding methods, production capacity can be increased by more than 3 times under the same labor conditions, while ensuring stable delivery schedules.

2. Adjustable Welding Head Spacing for Fast Product Changeover

For different workpiece specifications, the welding head assembly supports flexible adjustment within a certain range.

The spacing between each welding head can be fine-tuned to improve equipment adaptability.

No complete fixture replacement is required. Product changeover and debugging time are reduced by 80%, allowing one machine to cover the customer's main shelf panel product categories.

3. Easy Operation with Reduced Dependence on Skilled Welders

Each welding head group can be independently controlled for start and stop operations, allowing flexible selection of welding points and avoiding unnecessary welding energy consumption.

The machine is equipped with a visual touchscreen control system.

Key parameters including welding current, pressure, and holding time can be stored and recalled with one click.

Ordinary operators can independently operate the machine after half a day of training, reducing dependence on experienced welders.

4. Medium Frequency Inverter Welding System, Perfectly Suitable for 1.2mm Galvanized Sheet Welding

The self-developed medium frequency inverter DC welding system adopts three-phase balanced power supply and millisecond-level precise heat input control.

Advantages include:

• Quickly penetrates the galvanized coating and reduces zinc splashing;

• Produces smooth welding points with shallow surface marks, greatly reducing post-welding grinding;

• Ensures uniform and stable weld nuggets, eliminating weak welds and weld separation;

• Minimizes heat-affected areas, preventing thin sheet deformation;

• Improves product appearance consistency and reduces defective product rates.

IV. From Solution Design to Equipment Delivery, Every Step Focuses on Customer Needs

After the equipment arrived at the customer's factory, PDKJ engineers conducted on-site commissioning, including welding current adjustment, holding pressure optimization, and cylinder pressure setting.

Through continuous trial welding and process optimization, the welding strength, appearance quality, and production cycle fully met the customer's standards.

The complete welding solution was developed around the customer's production challenges and capacity goals, covering customized design, manufacturing, debugging, and technical service.

From early welding process analysis, solution customization, and equipment manufacturing to on-site installation, commissioning, and production launch, PDKJ always focuses on practical manufacturing applications.

By providing highly matched welding solutions, PDKJ helps customers achieve stable product quality, improve production efficiency, and reach their manufacturing targets.
