[0001] The present invention belongs to the technical field of laser processing, and specifically relates to laser drilling, and in particular to a laser drilling device for producing a ceramic substrate and a working method thereof. Background Art

[0002] When drilling holes in a ceramic substrate, the ceramic substrate needs to be transferred between a conveyor belt and a laser processing platform.

[0003] In the related art, magnetic suction is used to grab the ceramic substrate. In order to prevent the magnetic suction head from crushing the ceramic substrate, the magnetic suction force of the electromagnet is increased and a certain distance is placed between the magnetic suction head and the ceramic substrate. As a result, when the electromagnet is energized, the ceramic substrate directly collides with the magnetic suction head, which can easily damage the ceramic substrate.

[0004] Therefore, how to reduce the damage to the ceramic substrate caused by the collision of the magnetic suction head during grasping is currently an urgent problem to be solved.

[0005] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.

[0025] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0026] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0027] See also Figure 1 , Figure 1 The present invention shows a schematic structural diagram of a laser drilling device for producing ceramic substrates, comprising: a loading conveyor belt 100, a unloading conveyor belt 200, a laser processing platform 300, a loading assembly 400 and a unloading assembly 500; the loading conveyor belt 100 and the unloading conveyor belt 200 are both arranged on the side of the laser processing platform 300; the loading assembly 400 and the unloading assembly 500 are both arranged on the laser processing platform 300; the loading assembly 400 is suitable for conveying the ceramic substrate on the loading conveyor belt 100 to the laser processing platform 300 for laser drilling; the unloading assembly 500 is suitable for conveying the drilled ceramic substrate to the unloading conveyor belt 200 to complete unloading.

[0028] See also Figure 2 , the ends of the loading assembly 400 and the unloading assembly 500 are both provided with a magnetic suction head 600; the magnetic suction head 600 comprises: a connecting column 610, a buffer 620 and an electromagnet; the buffer 620 is arranged on the bottom surface of the connecting column 610; the electromagnet is fixedly arranged on the bottom surface of the buffer 620. By adopting the method that the magnetic suction head 600 directly contacts the ceramic substrate, the ceramic substrate is adsorbed, and the buffer 620 is used for buffering, so as to avoid the magnetic suction head 600 pressing the ceramic substrate when descending, thereby reducing the damage rate of the ceramic substrate during transportation.

[0029] In some embodiments, the buffer member 620 includes a connecting plate 621 and a plurality of elastic parts 622 ; the bottom of the elastic part 622 is fixedly connected to the connecting plate 621 , and the top of the elastic part 622 is fixedly connected to the connecting column via an anti-stuck part 6223 .

[0030] The plurality of elastic parts 622 are evenly distributed along the circumference of the connecting plate 621 , so as to evenly absorb the impact force generated when the magnetic suction head 600 contacts the ceramic substrate, thereby reducing the displacement of the elastic part 622 and the probability of the elastic part 622 being stuck.

[0031] Specifically, the elastic part 622 includes: a guide rod 6221 and a buffer spring 6222; the buffer spring 6222 is sleeved on the guide rod 6221; the bottom of the guide rod 6221 is fixedly connected to the connecting plate 621; the top of the guide rod 6221 passes through the anti-stuck part 6223.

[0032] By providing the anti-stuck portion 6223 , the offset of the guide rod 6221 is adjusted, thereby reducing the probability of the guide rod 6221 being stuck.

[0033] See also Figure 3 and Figure 4 In some embodiments, the anti-stuck portion 6223 includes: a connecting frame 6223a, a first clamping block 6223b and a second clamping block 6223c; the first clamping block 6223b and the second clamping block 6223c are arranged opposite to each other and are both slidably arranged in the frame body of the connecting frame 6223a; the first clamping block 6223b and the second clamping block 6223c are elastically connected to the connecting frame 6223a through corresponding return springs; the first clamping block 6223b and the second clamping block 6223c are respectively arranged on both sides of the guide rod 6221, and are suitable for clamping the guide rod 6221.

[0034] The guide rod 6221 is limited by the first clamping block 6223b and the second clamping block 6223c. When the guide rod 6221 is offset, the offset of the guide rod 6221 is buffered by the return spring, thereby preventing the guide rod 6221 from being directly stuck. After the magnetic suction head 600 is separated from the ceramic substrate, the first clamping block 6223b and the second clamping block 6223c correct the guide rod 6221 under the action of the return spring, thereby reducing the probability of the guide rod 6221 being stuck.

[0035] In a preferred embodiment, the shapes of the fitting surfaces of the first clamping block 6223 b and the second clamping block 6223 c and the guide rod 6221 are adapted to the side walls of the guide rod 6221 .

[0036] In some embodiments, the side wall of the guide rod 6221 is provided with two plug-in oblique blocks 6221a; the first clamping block 6223b and the second clamping block 6223c are provided with a plug-in slot 6223b2 at the adaption position with the corresponding plug-in oblique block 6221a. Through the cooperation between the plug-in oblique block 6221a and the plug-in slot 6223b2, when the buffer spring 6222 is squeezed, the two plug-in oblique blocks 6221a on the guide rod 6221 will open the first clamping block 6223b and the second clamping block 6223c, increase the clamping force on the guide rod 6221, thereby further reducing the deviation of the guide rod 6221 and reducing the probability of the guide rod 6221 being stuck.

[0037] See also Figure 5-Figure 6 In some embodiments, a supporting plate 6223b1 is disposed on the top surface of the first clamping block 6223b; a proximity switch 6223c1 is disposed on the top surface of the second clamping block 6223c; the laser drilling equipment for producing ceramic substrates also includes a control module; the control module is suitable for receiving proximity information of the proximity switch 6223c1, and judging whether the guide rod is stuck based on the proximity information.

[0038] Specifically, the steps of receiving the proximity information of the proximity switch 6223c1 and judging whether the guide rod is stuck based on the proximity information include: obtaining the buffer time T; when the control module continues to receive the proximity information, it indicates that the guide column is not stuck at this time; when the time t when the control module does not receive the proximity information is greater than the buffer time T, it indicates that the guide column is stuck at this time, and a jam reminder is issued.

[0039] The buffer time T is artificially set, and needs to be greater than the time it takes for the loading component and the unloading component to take the material.

[0040] In some embodiments, when the laser drilling device for producing ceramic substrates is not working, the first clamping block 6223b and the second clamping block 6223c are spread apart, so that the buffer spring 6222 extends from the top of the first clamping block 6223b and the second clamping block 6223c to restore the initial state. In order to ensure the elasticity of the buffer spring 6222, when the laser drilling device for producing ceramic substrates is not working, the first clamping block 6223b and the second clamping block 6223c are manually spread apart, thereby releasing the limit on the buffer spring 6222, so that the buffer spring 6222 extends from the top of the first clamping block 6223b and the second clamping block 6223c to restore the initial state, thereby improving the life of the buffer spring 6222.

[0041] At least one embodiment further provides a working method of the laser drilling device for producing a ceramic substrate as described above, comprising: S110: transporting the ceramic substrate to the loading conveyor belt 100; S120: The loading assembly 400 transports the magnetic suction head 600 to the top of the ceramic substrate, and pushes the magnetic suction head 600 downward until the magnetic suction head 600 contacts the ceramic substrate, and energizes the electromagnet to adsorb the ceramic substrate; S130: Control the loading assembly 400 to transport the ceramic substrate to the laser processing platform 300; S140: drilling holes in the ceramic substrate by using the laser processing platform 300; S150: After the punching is completed, the unloading assembly is controlled to transport the magnetic suction head 600 to the top of the ceramic substrate, and the magnetic suction head 600 is pushed downward until the magnetic suction head 600 contacts the ceramic substrate, and the electromagnet is energized to adsorb the ceramic substrate; S160 : Control the unloading assembly 500 to transport the ceramic substrate to the unloading conveyor belt 200 .

[0042] In summary, the present invention provides a laser drilling device for ceramic substrate production and a working method thereof, comprising: a loading conveyor belt 100, a unloading conveyor belt 200, a laser processing platform 300, a loading assembly 400 and a unloading assembly 500; the loading conveyor belt 100 and the unloading conveyor belt 200 are both arranged on the side of the laser processing platform 300; the loading assembly 400 and the unloading assembly 500 are both arranged on the laser processing platform 300; the loading assembly 400 is suitable for conveying the ceramic substrate on the loading conveyor belt 100 to the laser processing platform 300 for laser drilling; the unloading assembly 500 is suitable for conveying the punched ceramic substrate to the unloading conveyor belt 200 to complete unloading. The ends of the loading assembly 400 and the unloading assembly 500 are both provided with a magnetic suction head 600; the magnetic suction head 600 comprises: a connecting column 610, a buffer 620 and an electromagnet; the buffer 620 is arranged on the bottom surface of the connecting column 610; the electromagnet is fixedly arranged on the bottom surface of the buffer 620. By adopting the method that the magnetic suction head 600 directly contacts the ceramic substrate, the ceramic substrate is adsorbed, and the buffer 620 is used for buffering, so as to avoid the magnetic suction head 600 pressing the ceramic substrate when descending, thereby reducing the damage rate of the ceramic substrate during transportation.
