Abstract

The device has a base plate (1) attached to a positioning unit and arranged at a contact pin carrier (2) that is movable by laminated spring arrangements (4.1, 4.2), where the contact pin carrier is flexibly connected with another contact pin carrier (3.1). Contact pins (6.1, 6.2, 6.3) that are attached at the contact pin carriers are attached on defined contact points of a workpiece with a defined force. The contact pins implement a guided movement.

Description

The The invention relates to a device for the simultaneous actuation of a plurality of contact pins, wherein at least two attached to contact pin carriers Contact pins placed on defined contact points of a workpiece can be, where the contact pins a guided Perform movement and put it on the contact points with a defined force.

Especially for editing operations in the Electrical engineering and in mechatronics it is often necessary to have several Approaching points with a tool simultaneously in one operation. This is for example the case when setting glue dots, when applying contacts and embossing operations. In doing so, such Points arranged in series or other geometric arrangements be. Sometimes these points are arranged at different heights. In the electrical industry can This may be, for example, contact pads that have a very small area and are a short distance from each other.

Of the Invention is the object of a device of the initially specify the type mentioned for can be used at a small distance arranged contact surfaces, produced inexpensively and can be operated and insensitive to contamination is.

According to the invention Task with a device having the features specified in claim 1 contains solved.

advantageous Embodiments are specified in the subclaims.

The inventive arrangement solve the task with a component. The required function groups for guidance, force entry and height compensation are achieved with the design of a single component.

The Device contains a basic body, in all functional parts are integrated, which are arranged fixed to the frame is and on which a movable by means of a leaf spring assembly arranged first contact pin carrier which is articulated with preferably two further contact pin carrier connected is.

A advantageous embodiment provides that the articulated arrangement the contact pin carrier off Leaf spring assemblies exists. Conveniently, this parallel spring assemblies used.

Further Is it possible, that arranged on the further contact pin carrier pins relative to the on the first contact pin carrier arranged lead pin and the spring characteristics and spring travel the leaf springs are coordinated so that this after a predetermined actuation value rest with the same force on the respective contact points.

The arrangement according to the invention is characterized by a number of advantages. These include:

• 1. The device allows the simultaneous placement of multiple scanning elements on defined areas of a component in one operation. The areas may be closely adjacent and have any spatial arrangement.
• 2. Positioning can be done so that all areas are touched with a defined force.
• 3. Different mounting heights can be compensated by different compression of the sensing elements.
• 4. All functional tasks of the device, such as guidance of the stylus, structure of the contact force, height compensation for different contact points are performed by a component, whereby a low susceptibility is achieved.
• 5. Due to the structural design of the device in a single component, it is possible to produce by accumulation of material and material removal suitable leaf spring elements that perform the function of leadership and the force when touching multiple contact surfaces.
• 6. By appropriate dimensioning of the component defined force-displacement characteristics of the leaf spring elements can be generated.
• 7. By combining parallel and sequential arrangement of the leaf spring elements both relative movements between individual styli as well as the compression of the entire stylus combination is possible.
• 8. It is also possible that are approached by spatial spring structure multidimensional arrangements of Aufsetzpunkte.

The Invention will be explained in more detail below with reference to an embodiment. In the associated Show drawing:

1 a schematic representation of an arrangement with three points to be processed and

2 a variant in two views.

In 1 is shown in a schematic representation of an application in which at three processing points with a triply equipped tool simultaneously operations are performed.

2 shows an embodiment of the device. The device consists of a flat part and contains a body 1 which can be attached to a moving unit of a processing machine. A first contact pin carrier 2 is connected to this movable. The connection is made by two parallel spring arrangements 4 , The first contact pin carrier 2 is with two other contact pin carriers 3.1 and 3.2 articulated. The connection is also made by parallel spring arrangements 5.1 and 5.2 , The functional elements are made out of a steel plate. At the bottom of the contact pin carrier 2 . 3.1 and 3.2 are contact pins 6 attached. Since in the illustrated embodiment, three processing points to be approached with the same bearing force, there is a parent contact pin 6.1 , and two subordinate contact pin 6.2 and 6.3 which is relative to the first contact pin 6.1 can spring down. The strength, position and length of the worked-out leaf spring elements 4 and 5 determine the force-displacement characteristic of the arrangement. The respective deflections can be adapted to the tolerance compensation and the force adjustment to the respective conditions. In order to avoid damage or destruction of the device by excessive forces, stop pins between the moving parts 7 be attached.
