Detailed Description

The technical solutions of the embodiments of the present invention will be explained and illustrated below with reference to the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, and not all embodiments. Based on the examples in the implementation manner, other examples obtained by a person skilled in the art without making creative efforts fall within the protection scope of the present invention.

In the following description, directional or positional relationships such as the terms "inner", "outer", "upper", "lower", "left", "right", etc., are presented for convenience in describing the embodiments and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the invention.

Example 1

Referring to fig. 1-8, the present embodiment provides a diamond laser cutting machine, which includes a casing 1, a control module, and a laser head 2, a linear module 3, a truss 4, a jig 5, and a locking member disposed in the casing 1, and each component is specifically described below, as shown in fig. 1, for convenience of description, in the present embodiment, three axes of a space coordinate system, that is, an X axis, a Y axis, and a Z axis are used as references to specifically describe, where a Z axis direction may also be understood as a vertical direction or a height direction of the casing 1.

The laser head 2 is used for emitting laser along the X-axis direction, and the laser emitted by the laser head 2 cuts diamond.

The linear module 3 is used for driving the laser head 2 to linearly move along the Y-axis direction so as to enable the laser head 2 to generate a cutting path, when the laser head 2 is driven by the linear module 3 to linearly move back and forth along the Y-axis direction during cutting, diamond is cut back and forth, and at the moment, the cutting path of the laser head 2 (also can be considered as the walking path of the laser head 2, and can be specifically shown by referring to fig. 3) is the kerf position after the diamond is cut; wherein the linear module 3 preferably adopts a servo screw linear module.

The truss 4 is fixed in the casing 1, is long beam-shaped, is located at the front side of the laser head 2, and extends in the Y-axis direction.

Referring to fig. 2 and 3, the number of the tools 5 is several, and in this embodiment, the situation of 3 tools 5 is specifically shown; wherein the jig 5 is used for bearing diamond (namely diamond as shown in a part a in fig. 3 and 7), and one jig 5 corresponds to one diamond; and a plurality of jigs 5 set gradually on truss 4 along the Y axle direction, and every tool 5 all can dodge position and cutting position relative truss 4 and move between.

In the cutting position, as shown in fig. 3, the jig 5 is located in the cutting path, where the jig 5 is located in the cutting path, specifically, after the jig 5 carries diamond, the diamond on the jig 5 is located in the cutting path, so as to ensure that the laser head 2 can cut the diamond when walking along the cutting path.

In the avoidance position, referring to the state of the jig shown in the M part in fig. 4, the jig 5 deviates from the cutting path, so that the jig 5 is no longer in the cutting path of the laser head 2, and the laser head 2 cannot cut the jig 5 when walking along the cutting path.

The locking member is used for keeping the jig 5 in the cutting position, the locking member can be driven to unlock, and when the locking member is unlocked, the jig 5 starts to move from the cutting position to the avoiding position.

The control module comprises a detection unit and a controller, wherein the detection unit is used for detecting whether the diamond on the jig 5 is completely cut off, the controller is configured to send an unlocking signal to the controller when the diamond is completely cut off, and the controller controls the locking piece to unlock according to the unlocking signal, so that the jig 5 starts to move from the cutting position to the avoiding position and finally remains in the avoiding position, and the state of the jig is shown as the M part in fig. 4.

Normally, after the diamond is mounted on the jig 5, the jig 5 is held in a cutting position by means of a locking member, as shown in fig. 3; cutting the diamond on the jig 5 as the laser head 2 reciprocates along the cutting path; and after the diamond on a certain tool 5 is completely cut off, the detection unit can send an unlocking signal to the controller, so that the controller controls the locking piece of the tool 5 to unlock, and then the tool 5 moves to the avoiding position with the cut diamond, and even if the laser head 2 is still reciprocating along the cutting path, the tool 5 cannot be cut by the laser of the laser head 2 (because the tool 5 is deviated from the cutting path, as shown by the M part in fig. 4), thereby playing a certain protection role on the tool 5.

The jig 5 is switched from the cutting position to the avoiding position and is automatically controlled by the control module, so that the automatic cutting and avoiding can be automatically performed without artificial participation.

Finally, in this embodiment, the jig 5 is set to be capable of automatically switching to the avoiding position after the diamond is cut off, which has the meaning of protecting the jig 5 as described above; it is also possible to make a reference, specifically, it is normal that after all the diamonds are cut, the laser head 2 should be turned off as soon as possible to reduce the power consumption of the laser head 2, and in practice, since the kerfs formed after the diamonds are cut are very small, it is difficult to directly observe whether the diamonds are cut by human eyes, it is generally necessary to enlarge the kerfs on a display by means of a microscopic imaging device (e.g., an industrial camera) to determine whether the diamonds are cut, and since a plurality of diamonds are cut, the imaging device needs to be provided with a plurality of pieces corresponding to each diamond one by one, which is not advantageous for saving cost, and the plurality of imaging devices also complicate the distribution of components inside the whole laser cutting machine.

In this scheme, set up tool 5 into can be after cutting off the diamond and switch over to dodging the position automatically, so even do not set up microscopic imaging equipment and also can judge whether all diamonds are cut off, specifically, as long as observe whether all tools 5 all are in dodging the position, then indicate that all diamonds have all been cut off.

Because the structures of the jigs 5 are substantially the same, in this embodiment, one of the jigs 5 is taken as an example for specific explanation, and the specific structure of the jig 5 is as follows:

as shown in fig. 2 and 5, the jig 5 includes a swing arm 52 and a carrier block 51; the carrier block 51 is mainly used for mounting diamond and is fixedly mounted on the upper part of the swing arm 52, and the lower end of the swing arm 52 is rotatably arranged on the truss 4 around a rotation axis extending along the Y-axis direction; so that the swing arm 52 can drive the jig 5 to turn over along the rotation axis, so that the jig 5 generates a cutting position and an avoiding position in the turning process.

As shown in fig. 5, the carrier block 51 includes a carrier surface 510 for adhering to one side surface of the diamond, in the cutting position, the carrier surface 510 is perpendicular to the X-axis direction, that is, in the cutting position, the swing arm 52 and the carrier block 51 are both in a vertical state, and the carrier block 51 extends above the truss 4, at this time, the carrier surface 510 of the carrier block 51 faces the laser head 2, so as to ensure that after the diamond is mounted on the carrier surface 510, the surface of the diamond faces the laser head 2, so that the laser head 2 can walk and cut.

After the locking piece is unlocked, the whole jig 5 starts to overturn downwards towards the side direction of the truss 4 under the gravity and finally enters the avoiding position.

In order to assist the overturning of the jig 5, in this embodiment, as shown in fig. 4 and 8, a pin hole is formed on a side wall of the truss 4 near to the swing arm 52, a latch 42 is movably penetrated in the pin hole, a spring 43 is arranged in the pin hole, two ends of the spring 43 respectively abut against an end wall of the pin hole and an inner end of the latch 42, the latch 42 keeps a trend of extending outwards under the pushing of the elastic force of the spring 43, in a cutting position, the swing arm 52 is locked at the cutting position by a locking piece, and the latch 42 is pressed into the pin hole by the swing arm 52 against the elastic force of the spring 43, as shown in a state of fig. 8; when the locking member is unlocked, the swing arm 52 has no locking force of the locking member, and the latch 42 starts to extend outwards when the driving of the spring 43 is small, so that the swing arm 52 is pushed to turn over to the side far away from the truss 4, and the jig 5 is assisted to turn over to the avoiding position.

In this embodiment, one swing arm 52 corresponds to one locking member, and as shown in fig. 4 and 8, the locking member specifically includes an electromagnet 41 and a magnetic attraction member 521; the electromagnet 41 is mounted on the side wall of the truss 4 near the swing arm 52 and is electrically connected with the controller, the magnetic attraction piece 521 is arranged on the swing arm 52 and opposite to the electromagnet 41, and the magnetic attraction piece 521 can be an iron plate or the like. When the cutter is locked, the electromagnet 41 is electrified to generate magnetic force to attract the magnetic attraction piece 521 on the swing arm 52, so that the swing arm 52 is attracted, and the swing arm 52 is kept at the cutting position; when the controller receives the unlocking signal, the controller controls the electromagnet 41 to be powered off, at the moment, the magnetic force of the electromagnet 41 disappears, the attraction force is not generated on the magnetic attraction piece 521 any more, and the jig 5 turns downwards under the gravity to start turning to the avoiding position.

In order to enable the jig 5 to be kept at the avoiding position and not overturned excessively, in this embodiment, as shown in fig. 4, a blocking member 44 diffracting along the Y axis direction is fixedly connected to the side of the truss 4, and when the swing arm 52 overturns downwards, the swing arm 52 finally will be put on the blocking member 44 and blocked by the blocking member 44 from continuing to overturn downwards. Wherein the stopper 44 may be a long rod or a rope, which is not particularly limited herein.

In order to fix the diamond on the carrier block 51, as shown in fig. 5 and 7, a fixing member for fixing the diamond is provided on the top of the carrier block 51 in this embodiment, and in the cutting position, the fixing position of the fixing member to the diamond is located above the cutting path; in this embodiment, the fixing member preferably employs a first bolt 513, which is screwed onto the carrier block 51, when the diamond is fixed, the first bolt 513 is screwed, the inner end of the first bolt 513 is abutted against the outer surface of the diamond to fix the diamond, the first bolt 513 is located above the cutting path (see fig. 5), so that the first bolt 513 is located above the cutting slit of the diamond (i.e., the cutting position of the diamond), so that when the diamond is cut, as shown in fig. 6, the upper portion of the diamond (i.e., the portion a1 in fig. 6) is still fixed on the carrier block 51, while the portion of the diamond located at the lower side of the cutting slit (as shown in the portion a2 in fig. 6) begins to drop downward under its own weight, and finally the detecting unit is triggered and sends an unlocking signal to the controller.

In order to ensure that the diamond can remain on the carrier block 51 after cutting, in this embodiment, as shown in fig. 5, a side wall of the carrier block 51 facing the laser head 2 is provided with a placement groove 511 for placing the diamond, and the bottom of the placement groove 511 forms the carrier surface 510; the top opening of the placement groove 511 is provided for inserting diamond; slots 512 for inserting the edges of two sides of the diamond are formed in the slot walls of two sides of the placing slot 511, and the slots 512 on two sides mainly limit the diamond to prevent the diamond from being separated from the placing slot 511; the first bolts 513 may be provided two on sides of the two slots 512, respectively.

In addition, as shown in fig. 5, the two sides of the carrier block 51 are respectively provided with a notch 515 at the position of the cutting path, and the existence of the notch 515 can avoid the travel of the laser head 2, so as to prevent the two side edges of the carrier block 51 from being touched in the travel process of the laser head 2.

Since the diamond has a smaller volume and a lighter weight, after the diamond is cut, the cut lower side portion may not easily fall smoothly due to the dead weight, so in this embodiment, as shown in fig. 5 and 7, a sliding groove 514 is formed on the carrying surface 510, and in the cutting position, the sliding groove 514 extends along the Z-axis direction; the sliding groove 514 is slidably provided with a balancing weight 7, the balancing weight 7 can be attached to the lower part of the diamond, and the balancing weight 7 mainly plays a role of balancing the lower part of the diamond, so that the lower part of the diamond starts to fall downwards under the dead weight and the gravity of the balancing weight 7 after the diamond is cut off.

Referring to fig. 5 and 7, the specific structure of the counterweight 7 is: the balancing weight 7 is basically of a U-shaped structure and comprises a bayonet 71 and a locking piece, wherein one end of the bayonet 71 is provided with an opening for embedding the edge of the diamond; the locking piece is used for locking the balancing weight 7 at the lower part of the diamond, the locking piece adopts a second bolt 72, the second bolt is in threaded connection with the outer wall of the balancing weight 7, when the diamond locking piece is used, the balancing weight 7 is inserted into the edge position of the lower part of the diamond through the bayonet 71, then the second bolt 72 is screwed, the inner end of the second bolt 72 is abutted against the outer surface of the diamond, and the inner wall of the bayonet 71 is abutted against the inner surface of the diamond.

For the detection unit, the specific structure is as follows: as shown in fig. 5, it includes a power supply circuit and a detector for detecting whether the power supply circuit is turned on, and when the detector detects that the power supply circuit is in an open state, the detector sends an unlock signal to the controller, wherein the detector may be a current detector; the power supply circuit comprises two terminals 61, and when the two terminals 61 are connected, the power supply circuit is in a conducting state; conversely, when the two terminals 61 are not connected, the power supply circuit is in an open state.

Wherein, the two terminals 61 are disposed on the carrying surface 510 and are respectively disposed on the upper and lower sides of the cutting path, such that when the diamond is mounted on the carrying surface 510, the inner surface of the diamond contacts the two terminals 61 (refer to the state shown in fig. 3), the diamond corresponds to a bridge, the two terminals 61 are connected, the power supply circuit is in a conductive state, and the detector does not send an unlocking signal; when the diamond is completely cut off, the lower part of the diamond starts to drop downwards, at the moment, the lower part of the diamond is separated from the terminal 61 positioned at the lower side, at the moment, the two terminals 61 are not connected by the diamond, the power supply circuit is disconnected, at the moment, the detector sends an unlocking signal to the controller, and the controller controls the locking piece to be unlocked.

It is worth noting that in this way the diamond used needs to be a diamond capable of conducting electricity, such as a semiconductor diamond, in particular for example a boron doped diamond.

Example 2

The difference between this embodiment and embodiment 1 is that the detection unit is different from embodiment 1 in that, as described in embodiment 1, the applied detection unit needs diamond to be conductive, and the application range is small, so this embodiment provides another detection unit, specifically:

as shown in fig. 9, the detection unit includes a proximity switch 62, the proximity switch 62 is disposed at the bottom of the chute 514, the proximity switch 62 is electrically connected with the controller, when the diamond is cut off, the weight 7 falls along with the lower portion of the diamond, the weight 7 falls down along the chute 514, and finally the weight 7 falls to the position of the proximity switch 62 to contact the proximity switch 62, and at this time, the proximity switch 62 is triggered and sends an unlocking signal to the controller.

Example 3

This embodiment is further modified on the basis of embodiment 1 or embodiment 2 in order to be able to automatically shut down the laser head 2 as soon as possible after all diamonds have been cut off to reduce the power consumption of the laser head 2.

As shown in fig. 4, the laser cutting machine further includes a correlation switch, the correlation switch includes a transmitting tube 81 and a receiver 82, the transmitting tube 81 and the receiver 82 are both installed on the truss 4, and all the jigs 5 are located between the transmitting tube 81 and the receiver 82; the emitting tube 81 is used for emitting light along the Y-axis direction, in this embodiment, the emitting tube 81 may be a laser emitter, and the receiver 82 is disposed on an opposite side of the emitting tube 81 for receiving the light emitted by the emitting tube 81.

When the receiver 82 receives the light emitted by the emitting tube 81, the controller controls the laser head 2 to be turned off; the back side of the swing arm 52 is provided with a baffle 522, and in the cutting position, the baffle 522 is located in the light emitting path of the emitting tube 81 to block light.

So long as the diamond is not cut off, the swing arm 52 corresponding to the diamond is still at the cutting position, and the baffle 522 at the back side of the swing arm 52 can block the light of the emitting tube 81, so that the receiver 82 can not receive the light, and the laser head 2 still can work at the moment;

when all the diamonds are cut off, all the swing arms 52 enter the avoiding position, the baffle 522 at the back side of the swing arms 52 moves away from the light emitting path of the emitting tube 81 and does not block the light, the receiver 82 can normally receive the light, and then the receiver 82 feeds back a signal to the controller, and the controller controls the laser head 2 to be closed.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
