Import of wire harness dispensing equipment

Waterproofing is a critical aspect in the production of wiring harnesses. If the waterproofing of automotive wiring harnesses fails, it can easily cause various electrical systems to malfunction, affecting the comfort of the entire vehicle and posing significant safety risks. This article primarily introduces an automatic dispensing system used during wire harness processing. It not only addresses issues such as quality hazards, poor consistency, and low efficiency in the dispensing process during automobile manufacturing, but it also enhances product reliability and prevents losses during production, thereby improving production efficiency.

Project Description

The automated wire harness dispensing system is introduced to improve production efficiency and quality stability.

Why Buy:

1. It reduces production costs and improves efficiency by making better use of manpower and material resources, thus enhancing production capacity.
2. The dispensing system is easy to operate, allowing employees to get up to speed quickly.

What Will Happen if You Don’t Buy:

Without the system, the amount of manually dispensed glue will be uneven, and the dispensing quality cannot be guaranteed.

The equipment replaces manual labor, with personnel only needing to load and unload materials. Training time is short, and employees can start using the system quickly.

Dispensing Principle

Based on the specific characteristics of the glue, the equipment uses air pressure to evenly apply the glue to the designated position within the set time. The system controls the timing and speed of each injection to ensure consistent droplet size, allowing for better control of glue output. This results in more stable lines and stronger bonding force.

It is estimated that with one piece of equipment and one set of tooling, the output can reach 200 pieces per hour, with a yield rate of 99.9%.

(Loading and unloading: one person operates one machine)

Although the tooling may seem simple, the real challenge lies in the part where the materials are fixed. This section needs to maintain a certain degree of flexibility in order to not only secure the materials but also facilitate easy loading and unloading.

The essence of automation is in standardized product and tooling standards, which make automation easier to achieve. Therefore, analyzing the dispensing action and its requirements is the main focus.

While the equipment is dispensing glue, the operator places the material on another tool and performs a cyclical operation to reduce both the number of equipment downtimes and the time spent on each downtime.

By adopting the concept of lean production, the system is suitable for "multi-variety, small-batch" production modes. Only a small number of operators and machines are needed to work together, reducing the need for manpower. This allows for normal production even with changes in output or personnel.

The automobile wiring harness serves as the carrier that connects various components of the automobile circuit. It is composed of sheaths, terminals, wires, and more. For example, the automobile wiring harness is like blood vessels in the human body; the engine is the heart. The heart beats because of the blood vessels, and the engine runs because of the wiring harness. This analogy highlights the crucial role the wiring harness plays in the normal functioning of the vehicle’s electrical system, making it essential to ensure the waterproofing of the harness.

To effectively manage the dispensing process of the wire harness, it is necessary to first clarify the functional requirements of the dispensing process. These can be summarized as follows:

1. Assist with and maintain the positioning and assembly of the wiring harness.
2. Facilitate a convenient dispensing process.
3. Ensure the glue solidifies easily (it should also solidify quickly at low temperatures).
4. Be suitable for subsequent processes such as welding (high temperature and long-duration exposure to heat).
5. Be non-corrosive to the product and non-toxic to both the environment and human health.

Based on the specific configuration, the accuracy of repeated displacement and movement is crucial to achieving precise dispensing.

In principle, improvements at the grassroots level focus on cost control and process optimization. By identifying opportunities to reduce costs, minimize waste, or improve labor efficiency, and conducting feasibility analyses, small but impactful improvements can be made. The above is the author’s simple experience in enhancing the dispensing process, and it is hoped that it will be helpful to readers.
