As shown in fig. 1, includes: a master control card 110 for controlling the master processing head, a slave control card 120 for controlling the slave processing head, and a synchronization control card 130.
When receiving marking ready signals sent by the master control card 120 and the slave control card 130, the synchronous control card 110 outputs synchronous signals to the master control card 110 and the slave control card 120; when receiving the synchronization signal, the main control card 110 and the sub control card 120 respectively send marking start signals to the main processing head and the sub processing head, and control the main processing head and the sub processing head to start marking at the same time. Fig. 2 is a circuit diagram of the synchronous control card and the master and slave control cards in one embodiment. The output ends of the master control card (marking card 1 in the figure) and the slave control card (marking card 2 in the figure) are connected with the input end of the synchronous control card, and a marking ready signal is sent to the synchronous control card; the output end of the synchronous control card is connected with the input ends of the main control card and the auxiliary control card, and synchronous signals are sent to the main control card and the auxiliary control card. In this embodiment, the synchronous control card adopts 4-way synchronous control card.
The main control card is connected with the main processing head and used for controlling marking of the main processing head, and the auxiliary control card is connected with the auxiliary processing head and used for controlling marking of the auxiliary processing head; the synchronous control card controls the main control card and the auxiliary control card, and specifically, the synchronous control card receives marking ready signals sent by the control cards, and sends synchronous signals to all the control cards after the marking ready signals of all the control cards are detected, wherein the synchronous signals are used for informing the main control card and the auxiliary control card that corresponding processing heads start marking. That is, the master control card sends a marking start signal to the master processing head when receiving the synchronization signal, and the slave control card sends the marking start signal to the slave control card when receiving the synchronization signal. Therefore, the main control card and the auxiliary control card send marking start signals at the same time, namely the main processing head and the auxiliary processing head start marking at the same time.
In one embodiment, the main control card and the auxiliary control card send marking ready signals to the synchronous control card when receiving the machining instruction. When all preparations are ready before machining, a user opens the machine to start machining, and at the moment, machining instructions are sent to the master control card and the slave control card. Since the hardware element parameters of the control cards are not identical, the output signals of the master control card and the slave control card may have a certain time difference, for example, as shown IN fig. 3, which is a schematic diagram of the input signals (IN0, IN1), the output signals (OUT0, OUT1) and the marking signal (MARK) of the synchronous control card IN one embodiment; the signals output by the master control card and the slave control card (i.e. the input signals IN0 and IN1 of the synchronous control card) have a certain time difference, and after passing through the synchronous control card, the signals of the master control card and the slave control card are synchronized, so that the signal time difference caused by hardware parameters between the master control card and the slave control card can be eliminated.

The main control card and the auxiliary control card can send marking ready signals to the synchronous control card before the laser emits light every time, and only when the synchronous signals sent by the synchronous control card are received, the main processing head and the auxiliary processing head are respectively controlled to mark. The multi-head laser processing control system has the advantages that each time the laser emits light, signals are synchronized through the synchronous control card, and the situation that graphs processed by a plurality of processing heads deviate farther and farther due to time accumulation can be avoided.
In one embodiment, the master control card is connected with the laser controller, and the master control card controls the laser controller to send a turn-on signal or a turn-off signal to the laser.

The beam splitting module is used for splitting a laser beam into a plurality of light beams (the light beams are split by a plurality of processing heads); the light splitting module can realize light splitting in a plurality of different modes, and only the laser energy split by different processing heads is ensured to be consistent.
In the control system shown in fig. 4, when a processing instruction is received, the master control card controls the laser controller to send an opening signal to the laser, the laser is controlled to start emitting light, and the laser is divided into two laser beams with equal energy in the light splitting module to enter the 1# square head and the 2# square head respectively; the main control card and the auxiliary control card respectively send marking ready signals to the synchronous control card, and the synchronous control card simultaneously sends synchronous signals to the main control card and the auxiliary control card after receiving the marking ready signals of the main control card and the auxiliary control card; and when receiving the synchronous signal, the main control card and the auxiliary control card respectively send marking start signals to the 1# square head and the 2# square head, and control the 1# square head and the 2# square head to start marking at the same time.
In order to ensure the synchronization of marking among a plurality of processing heads, in addition to the process of multi-head laser processing equipment delivery through a synchronous control card in the processing process, the BOX (BOX) correction needs to be carried out on the processing parameters of each processing head.

In one embodiment, when the main control card receives a general correction instruction, the main processing head is controlled to mark on the test board according to the general correction instruction to obtain a main processing head test pattern, and the processing parameters of the processing head are adjusted based on the general corrected processing parameters of the main processing head, wherein the general corrected processing parameters of the main processing head are determined based on the main processing head test pattern.
In this embodiment, when receiving a multi-point correction instruction, the master control card controls the main processing head to mark on the test board based on the normal correction file of the main processing head to obtain test point data of the main processing head, and the normal correction file of the main processing head is determined based on the processing parameters after the normal correction of the main processing head; the main control card also adjusts the processing parameters of the main processing head based on the multi-point corrected processing parameters of the main processing head, wherein the multi-point corrected processing parameters of the main processing head are determined based on the test point data of the main processing head.

In a multi-head laser processing apparatus, in order to ensure the synchronization of the marking by a plurality of processing heads, the processing heads need to be corrected, and the marking effects of the processing heads need to be made uniform. In this embodiment, the correction is performed on the main processing head first, and then the correction is performed on the document which is corrected by the sub processing head based on the main processing head.

In one embodiment, the present application also provides a dual head four station machine, for dual head laser machining applications, having two machining heads, the complete machine consisting essentially of the following 6 parts: an upper and lower cabinet, a laser, a lifting body, a light splitting module, a double processing head, a turntable and a jig for supporting and protecting the whole laser system are shown in fig. 10. In this embodiment, the elevating system supports the laser, the beam splitting module and the processing head, and the laser focus position of the double processing heads can be adjusted by elevating the height of the Z axis, and the energy of the laser is divided into two parts and evenly distributed to 2 processing heads by the external light path beam splitting module after the laser emits light. The light splitting module can realize light splitting in a plurality of different modes, for example, film coating light splitting or dynamic light splitting can be adopted. Fig. 11 is a schematic diagram of a light splitting part in one embodiment.
In the dynamic light splitting mode, adjustable optical lenses such as a wave plate and a polarizing film can be specifically installed on an outer light path, and because laser is polarized light, reflection and refraction of the light can be adjusted by changing a polarization angle, so that energy of each head can be dynamically adjusted; the coating light splitting is the adjustment of a lens, namely, the light splitting lens is directly coated on an external light path according to the ratio of reflected energy to transmitted energy, for example, in the embodiment of two processing heads, the light splitting lens of a main processing head adopts 50% reflection and transmission coating, and the light splitting lens of an auxiliary processing head is 100% reflection coating lens.
In the embodiment that the light splitting module adopts dynamic light splitting, before the double-head four-station machine is used for processing, whether the laser energy of each head is equal or not needs to be tested, specifically, whether the power of a plurality of processing heads is consistent or not needs to be tested, and if deviation occurs, the power test is carried out again after the light splitting module needs to be adjusted. After the energy is adjusted uniformly, the laser multi-head marking software is started to carry out the synchronism test, the synchronism test is carried out by a preset pattern, for example, square filling or round filling, and if the synchronism test is not passed, the synchronism test is carried out again after the adjustment; if the synchronism test is passed, the processing of the product can be started. Wherein the power test and the synchronicity test can be implemented in any of a variety of manners. When the power and the synchronism are confirmed to be uniform, the product production can be carried out, the double-head four-station machine adopts a design of a turntable rotating mechanism which processes and discharges materials simultaneously, the production efficiency can be improved, and the specific processing flow is shown in figure 12.
According to the double-head four-station machine, firstly, due to the fact that the double-head four-station machine comprises the light splitting module and the two processing heads, a plurality of products can be processed at the same time, the laser is the most core part of laser equipment, the price is the largest cost, the cost of the core part is not increased after multi-head processing is adopted, the cost of a user can be reduced, and the processing efficiency is improved in a multiplied mode; secondly, because the space of a plurality of machines (the equipment of two processing heads is equivalent to two normal laser processing equipment) is integrated into one machine, the occupied space is reduced in practical application, the cost is reduced, and in addition, the labor cost can be reduced by a plurality of times. One laser is divided into a plurality of processing modes, and one device is equivalent to two same devices for processing simultaneously in terms of production effect. In general, the cost of laser processing can be reduced, and the processing efficiency can be improved.
