Built-in Crimp Force Monitor (CFM)

CFM captures, calculates and evaluates force-time curve and detects any deviation from the quality tolerances.

System works with many types of splicing and crimping machines and suites well to any application requiring inline monitoring of forces.

The reference curve of CFM corresponds to crimping force, but in fact it can reflect such quality deviations as:

• missing wire strands,
• missing terminal,
• inaccurate components positioning,
• inaccurate crimp height,
• inaccurate wire gauge,
• insufficient insulation strip length,
• insulation in wire barrel,
• wire partially inserted in wire barrel.

CFM allows to adjust automatic cutting and/or rejection of defective items.

Splice band
Splice band is defined according to the type of application and environment temperature range: splice band type and material (brass, brass with tin coating, cupronickel,cupronickel with tin coating, stainless steel), thickness (0.2 – 0.53 mm), width (1.5, 2, 3, 4, 6, 7 mm), and length.

Splice band is engineered with serrations for magnet wire and standard wire types. It is suitable for multi-strand and solid core copper and aluminum wires.

Our splice materials meet the following standards:

• UL 486C
• MIL – STD 202
• IEC 60352-2
• IPC/WHMA-A -620
• REACH & RoHS

Crimp height adjustment
Motorized crimp height adjustment is realized via touch screen with buttons +- (increment of 0.01 mm) or by selecting among preadjusted connections parameters (automatically).

Motorized splice band feeding system
Rubber surface of a feeding wheel prevents damages of the splice band. Special sensor controls the length of each splice.

Touch screen control panel
All controls except the power switch are located at the display. With 5 buttons and 1 display it is possible to control the quantity of products, inputs and outputs, interface language, tooling technical data, feeding system and activate emergency stop.

It indicates the process of each crimp in a jig.

Hand wheel
Hand wheel is used to perform manual cycle for testing the system before production, i.e. centering the clincher, change of tooling. Wheeling moves the punch down and allows to monitor splicing process in general as well as positioning of the tooling.

Crimping tooling set
Tooling set includes clincher, anvil, punch, punch guide, and cutting block.

Such parameters as clincher type, clincher size, and punch tip shape are customized for the application.

Inclined clincher surface, smooth cutting surface, quick-change tooling cassette, and finger guard lighting cap guarantees efficient & safe operation.

Data memory in each tooling cassette stores its own tooling list (PN’s) and connection data for up to 10 connections with independent crimp height settings. It enables automatic correction of crimp height when the cassette is installed.

Automated YZ fixture table

Enables shifting the jig with components to the zone of crimping with Y and Z axes capability. High movement accuracy is achieved through programmable actions. Control over the YZ table is provided at the HMI screen, including control of stepper motor drives of the table.

Operator is protected by safety covers.

Support for the jig precisely carries the jig to the crimping zone.

Jig
Removable part of a fixture that perfectly fits components and thus enables its precise positioning. Jig can be adapted to components depending on its quantity, shape, materials.

If machine has two jigs, while one is processing, second can be reloaded by another operator.

Cast iron frame
In contrast to the machines assembled from separate parts by screws, SM Crimp cast iron frame warrants a perfect stability during crimping.

HMI

On the touch screen display HMI system shows complete work algorithm, indicating the current step and step when the failure occurred if any. It can be displayed as an algorithm graphics or product visualization.

HMI provides intuitive process control. It is possible to readjust all sensors including CFM to another product by choosing the corresponding program in the interface. HMI displays pictures of connections kept in memory when the tooling cassette is installed and the corresponding connection selected for processing.

Within the password protected area one can switch machine subfunctions on/off. Different access levels (operator and technician) are available at HMI touch screen.

Component position video verification

Camera shoots the clincher area and sends video to the HMI screen in real time. Thus, operator can view the components being crimped and is capable to position them in the clincher precisely.

There are two options for the camera placement:

1, built into the tooling cassette,

2, mounted on the left wall of the tooling cassette and connected via USB cable.

Protection of operation area

Safety covers can be installed on the side panels to detect foreign object presence and stop the machine.

Bimanual cycle start

Requires two hands touch to start the cycle to eliminate hands presence in the work zone.

POKA YOKE

Allows controlling utilization of NG/NOK components. If CFM detects quality deviation and estimates connection as NG/NOK, then machine stops operation and waits until NG/NOK component is placed to POKA YOKE bin.

Components camera control

According to the selected program, high/low definition camera takes pictures and controls components` presense, position, color and stripping length. High or low definition is selected depending on size of components.

Force sensor for CFM

Piezo sensor detects force at the moment of splicing, transmits information to CFM for data processing and displaying force-time curve corresponding to crimp force.

Frame & cabinet

Machine and all its components can be integrated into the floor mount frame for products needs.

Quality control equipment

Laboratory equipment allows to control whether the splice quality matches industry norms or any other special requirements. Check our micrograph laboratories, pull force and crimp height control tools, as well as specialized measurement software.

Double crimping

Two machines are used: one set up for one splicing type, another – for the second. This solution speeds up the process and perfectly fits if the product consists of different sized crimping.
