[0055] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0056] As described in the background technology, most existing equipment has only one operation panel, which has great limitations in use. To solve the above problems, this embodiment sets two operation panels on the LED product laser processing equipment. When the two operation panels independently operate and control the equipment, the two operation panels are prevented from interfering with each other and causing safety accidents. An interlocking control system based on dual operation panels is set to interlock the two operation panels, so that the two sets of operation panels can independently operate and control the equipment, thereby improving the safety of the equipment.

[0057] Embodiment 1:

[0058] like Figure 1As shown, the interlocking control system includes: a first power supply circuit KA, a second power supply circuit KB, a first start-stop circuit KD and a second start-stop circuit KE, wherein the first power supply circuit KA supplies power to the first start-stop circuit KD, and the second power supply circuit KB supplies power to the second start-stop circuit KE.

[0059] In this embodiment, the first power supply circuit KA and the first start-stop circuit KD are controlled by a first operation panel, and the second power supply circuit KB and the second start-stop circuit KE are controlled by a second operation panel.

[0060] The first power supply circuit KA includes a first key button SY0A and a relay A, wherein the relay A includes a normally open contact A1 and a normally closed contact A2; the second power supply circuit KB includes a second key button SY0B and a relay B, wherein the relay B includes a normally open contact B1 and a normally closed contact B2; the first key button SY0A and the second key button SY0B are used to control the first power supply circuit KA and the second power supply circuit KB, respectively.

[0061] Among them, the normally open contact A1 is connected in parallel with the first key button SY0A, and the normally closed contact A2 is connected in series between the second key button SY0B and the relay B; the normally open contact B1 is connected in parallel with the second key button SY0B, and the normally closed contact B2 is connected in series between the first key button SY0A and the relay; specifically, when the relay A is energized, the normally closed contact A2 between the second key button SY0B and the relay B is disconnected. At this time, when the second key button SY0B is rotated again, the current in the second power supply circuit KB cannot be conducted, and the device can only be controlled through the first operation panel, and the second operation panel is invalid; similarly, when the relay B is energized, the normally closed contact B2 between the first key button SY0A and the relay A is disconnected. At this time, when the first key button SY0A is rotated again, the current in the first power supply circuit KA cannot be conducted, and the device can only be controlled through the second operation panel, and the first operation panel is invalid.

[0062] The interlock control system also includes a device power start-stop circuit, wherein the relay A includes a normally open contact A3, and the relay B includes a normally open contact B3. The device power start-stop circuit is provided with a main power supply power contactor KM0, and the normally open contact A3 and the normally open contact B3 are respectively connected in parallel between the main power supply power contactor KM0 and the DC power supply input terminal. That is to say, when the first key button SY0A is rotated, the corresponding relay A in the first power supply circuit KA is energized, and the normally open contact A3 is closed, so that the main power supply power contactor KM0 is energized; similarly, when the second key button SY0B is rotated, the corresponding relay B in the second power supply circuit KB is energized, and the normally open contact B3 is closed, so that the main power supply power contactor KM0 is energized.

[0064] In this embodiment, in order to quickly disconnect the current flow of the control machine circuit in an emergency, the first emergency stop button SB7 and the second emergency stop button SB8 are connected in series between the safety relay C and the DC power input terminal. The first emergency stop button SB7 and the second emergency stop button SB8 are both normally closed contacts, and the first emergency stop button SB7 and the second emergency stop button SB8 disconnect at least one normally closed contact to achieve the current interruption of the safety relay C. At the same time, the safety relay C also includes a normally open contact C2 and a normally open contact C3, which are respectively arranged in the first start-stop circuit KD and the second start-stop circuit KE. When the safety relay C is disconnected, the normally open contact C2 and the normally open contact C3 are also disconnected, thereby disconnecting the first start-stop circuit KD and the second start-stop circuit KE, thereby stopping the operation of the laser KA2A or the laser KA2B.

[0067] The first machine power-on button SB1A and the first machine power-on button SB1B are used to control the first start-stop circuit KD and the second start-stop circuit KE, respectively. Specifically, when the first power supply circuit KA is energized, the first machine power-on button SB1A controls the relay D to be energized, so that the normally open contact D1 is energized and closed, thereby energizing the first laser start circuit; similarly, when the second power supply circuit KB is energized, the first machine power-on button SB1B controls the relay E to be energized, so that the normally open contact E1 is energized and closed, thereby energizing the second laser start circuit. The operator can control the start and stop of the laser KA2A and the laser KA2A respectively through the start button SB2A and the start button SB2B.
