Application case of stamping production line: Double tension detection of white steel sheet for automotive cylinder gasket (MDSC-1000B shooting scheme)

1、 Case Overview

This application is aimed at the pain points of the automotive cylinder gasket stamping production line: the production line adopts a robotic arm for automatic feeding, and the thickness of the white steel sheet used is only 0.15-0.5mm. Due to the surface rust proof oil film and electrostatic adsorption, stacking and feeding problems frequently occur. Double sheet materials entering the mold can easily cause mold breakage, product scrap, and a single mold repair cost of tens of thousands of yuan, resulting in long downtime.

On site installation of AtormMDSC-1000B dual beam detectorBy relying on the positioning signal of the robotic arm to trigger detection, double stack materials are intercepted from the source without affecting the original rhythm of the production line, perfectly adapting to the detection scene of extremely thin oil contaminated metal sheets.

2、 Customer core pain points

The customer is a professional automotive parts stamping enterprise with extremely high precision requirements for cylinder gasket stamping molds. The stacking problem causes multiple production losses, and the original solutions are ineffective:

• Extremely thin stacking is difficult to identify: The thickness difference of 0.15-0.5mm white steel sheet stacking is extremely small, and the mechanical arm suction cup force feedback cannot identify it, resulting in extremely low manual inspection efficiency.

• High cost of mold wear and tear: Double clamping molds can easily cause precision molds to break and deform, resulting in 8-10 serious accidents per year. The cost of mold repair alone can reach 100000 yuan, and combined with downtime and product scrap losses, the production cost increases significantly.

• Working condition interference detection: The steel surface has a serious oil film and reflection, and the traditional photoelectric detection has a very high false alarm rate, making it difficult to use stably; The blowing separation scheme is not suitable for extremely thin materials, which can easily blow away materials or cannot separate stacked materials.

3、 Solution: MDSC-1000B dual beam detection scheme

1. Core advantages of selection

Compared with the photoelectric detection scheme, the 1000B reflective detector is more suitable for the stamping scene of ultra-thin and oily white steel sheets: relying on the principle of magnetic induction penetration detection, it is not affected by the surface oil film, reflection, and dust of the material; Up and down shooting penetration detection, with clear signal difference and sufficient detection margin for 0.15mm extreme thin materials, far exceeding the stability of other solutions.

2. On site installation and testing process

No need to modify the main structure of the production line, only symmetrically install dual probes above and below the mechanical arm alignment station to accurately match the mechanical arm material retrieval and alignment position, fully embedded in the original production process:

1. The robotic arm grabs the white steel sheet and moves it to the alignment station to complete precise positioning;

2. The robotic arm PLC automatically outputs signals, triggering the detector for rapid detection;

3. Detected as a single piece of material, normal feeding and stamping; Detected as double sheet, immediately sound the alarm, and the robotic arm will retract to retrieve the material again.

4、 On site testing effect

After the implementation of the plan, the problem of thin material stacking punching dies has been completely solved, and the stability of the production line has been greatly improved. The core improvement effects are as follows:

The problem of double sheet stacking has been solved, and double sheet molding accidents are approaching zero;

The frequency of abnormal maintenance of molds has significantly decreased, completely eliminating high cost mold repair and downtime losses;

Strong anti-interference ability, oil stains, equipment vibration, and material thickness fluctuations do not affect detection accuracy, and the false alarm rate is extremely low;

Fully adapted to the original production line rhythm, with no loss in production efficiency and extremely low daily maintenance costs.

Customer review: In the past, there were frequent occurrences of double sheet molding for thin materials, and the downtime for mold repairs seriously delayed order delivery. install additionally1000B dual detectorAfterwards, the stacking problem was solved from the source, with stable molds and smooth production lines, greatly reducing production costs.

5、 Frequently Asked Questions and Answers

Q1: How to choose a pair/single probe detector for thin material stamping?

Both options are acceptable. There is installation space available for both upward and downward options, with the option to select the opposite type and the limited space option to select the probe contact type.
