Definitions
- the invention relates to a level detection for electrode cap magazines of welding electrodes.
- spot welding is often used to connect metal sheets and strips in body production in automated production lines.
- Welding robots are usually used here in order to
- These welding robots are equipped with welding tongs, whose
- Electrode caps are equipped.
- Welding tongs for the sheets to be welded and the arrangement of the sheets in relation to one another are automated and computer-aided.
- the electrode caps in particular are subject to a high level
- Burn-off beads often form at the edge of the contact areas, which change the area by increasing the contact area
- the electrode caps are reworked regularly and depending on their load and the resulting wear and tear by milling.
- Interacting electrodes of a welding gun will often wear to the same or a similar extent, so that they have to be reworked regularly and at the same time by milling.
- the electrode cap After a number of post-processing operations, the electrode cap has been removed to such an extent that it has to be replaced.
- Action areas of the active robots may move.
- the magazines were also changed.
- Electrodes in particular for welding guns of welding robots. This solution suggests that the electrode caps to be stored in a magazine in a row in their profile the shape of the electrode caps
- cap guides which are designed parallel to the longitudinal axis of the magazine and identical to the position in the removal opening.
- the removal opening is opened so far in the direction of access of the welding gun that a welding cap is arranged with its opening positioned in the direction of the access and its entire access is exposed.
- the invention has for its object to propose a solution with which the difficulties of previously known solutions are avoided as far as possible and an accurate detection of the level of the
- Electrode cap magazine is made possible.
- This exemplary embodiment shows a solution to the problem according to the invention using the example of an electrode cap magazine consisting of a magazine head 1 and an exchangeable magazine 2.
- Figure 1 shows a detailed view of the electrode cap magazine with the level detection according to the invention in a decoupled state with sensor 7 and measuring surface 8
- Figure 2 shows a two-channel magazine head 1 with one sensor 7 for each electrode cap channel 5
- Figure 3 shows a detailed view of the measuring beam from the sensor 7 on
- Figure 4 shows an electrode cap magazine with level detection according to the invention in a coupled state.
- the electrode cap magazine according to the invention consists of a magazine head 1 and an exchangeable magazine 2.
- Quick-action clamping device 4 and 4a are arranged in such a way that the tensioner 4 is arranged on the magazine head 1 and the tensioning hooks 4a are arranged on the change magazine 2. This arrangement makes technical sense, because in the direction of force of the
- At least one guide device is arranged.
- this guide device is preferably designed in such a way that it can be easily brought into engagement and still has a defined position of the magazine head 1 and the
- Interchangeable magazine 2 is guaranteed to each other.
- the electrode caps 3 are stored in the interchangeable magazine 2 and in the magazine head 1, the interchangeable magazine 2 and the magazine head 1 being equipped with two electrode cap channels 5 according to the exemplary embodiment and the illustrations, which are designed parallel to the longitudinal axis of the interchangeable magazine 2 and also identical in position to the magazine head 1 are.
- the electrode cap channels 5 are inserted diagonally offset in the exchangeable magazine 2 and magazine head 1 in such a way that the electrode caps face each other diagonally offset with respect to one another.
- the idea of the invention also includes technical ones
- Electrode cap channels 5 When using several electrode cap channels, these are arranged diagonally offset opposite one another in the cross section of the exchangeable magazine 2 and magazine head 1. This arrangement of the electrode cap channels 5 was chosen in order to achieve the smallest possible size of the unit, since the overall height of the device is thus less than the height of two
- the electrode cap channels 5 are designed such that the electrode caps 3 can be transported with little force and are located in the electrode cap channel 5 and in particular on the
- Tilting of the caps 3 is prevented. This is achieved in that these electrode cap channels 5 are designed in the form of the electrode caps 3 plus corresponding tolerances.
- each electrode cap channel 5 there is at least one cap conveyor 6 which is arranged in a linearly movable manner and is preferably loaded with spring force and which contains the cap conveyor 5 contained in the electrode cap channel 5
- the position of the cap conveyor 6 contained in the electrode cap channel 5 depends on the number of electrode caps 3 located in the exchangeable magazine 2 and in the magazine head 1.
- At least one sensor 7 for position measurement is arranged in the magazine head 1. This sensor 7 projects onto at least one in the measurement channel 9 of the
- Exchangeable magazine 2 contained measuring surface 8, for example a
- Reflection surface a measuring beam for measuring the distance between sensor 7 and measuring surface 8.
- a reflection light scanner can be used as the sensor 7, for example, which illuminates the reflection surface, which serves as the measurement surface 8.
- a measuring surface 8 is mechanically connected to the cap conveyor 6 in such a way that the measurement in a parallel to the electrode cap channel 5
- measuring channel 9 is realized and thus the direct relationship between the number of electrode caps 3 in the electrode cap channel 5 and the position of the measuring surface 8 in the measuring channel 9 applies.
- Electrode caps 3 are determined.
- Electrode caps 3 can be planned individually, since, according to the invention, not only the degree of reporting filling is reached, but also the exact number of
- Electrode caps 3 is detected.
