Description

Technical Field

[0001] The invention relates to the technical field of circuit board processing, and in particular to circuit board laser cutting equipment. Background Art

[0002] After circuit board manufacturing or assembly, the designed circuit board prototype or finished product needs to be cut according to specific sizes and shapes. The purpose is to divide the larger circuit board panel into separate functional units. Circuit board laser cutting is a modern precision processing technology that uses a laser beam to cut, punch or engrave circuit board materials. It has the advantages of non-contact, high precision, flexibility and speed.

[0003] In the current circuit board laser cutting process, in order to ensure that the circuit board remains stable during the cutting process, a clamp or a special fixing device is usually used to fix the circuit board to ensure that it does not move during the entire cutting process. However, the limiting effect of a single limiting device is poor and the clamping range is limited. Secondly, during the laser cutting process, harmful smoke and dust will be generated, and carbonization will occur on the processed surfaces of the circuit board and PCB board, which will affect the appearance and performance of the circuit board. Furthermore, after the laser cutting is completed, the connection between the circuit board and the PCB board needs to be manually broken, which is not conducive to continuous operation. Manual splitting is inefficient and can easily cause damage to the circuit board.

[0018] Compared with the existing technology, the advantages of the present invention are: 1.

[0037] First, the lower conveyor belt 1 and the upper conveyor belt 2 are both intermittently driven, and the lower conveyor belt 1 and the upper conveyor belt 2 always maintain the same speed transmission. The circuit board to be processed is placed on the top wall of the lower conveyor belt 1, and the adjusting wedge block 44 and the upper and lower material wedge block 3 are gradually approached until the adjusting wedge block 44 and the upper and lower material wedge block 3 are in contact. The adjusting wedge block 44 moves down with the bottom wall of the upper and lower material wedge block 3, driving the support frame 42 to slide downward along the three round rods of the fixed block 41, and the first reset spring 43 is stretched accordingly, and the support frame 42 drives the suction cup limit assembly 5 to move toward the upper material fixed assembly 6.

The protective cover 72 can prevent harmful smoke and dust from spreading outward during the processing. An existing absorption and filtering device can also be installed in the protective cover 72 to absorb and filter harmful smoke and dust generated during cutting. When the laser cutting head 75 performs laser cutting, the blowing head 76 blows compressed air to the processing part of the circuit board. The blowing head 76 blows away the residue generated during cutting and helps cool the processing surface of the circuit board, which can reduce the carbonization phenomenon and reduce the impact of carbonization on the appearance and performance of the circuit board. The blown debris falls through the lower conveyor belt 1 into the collection bin 77, and falls along the inclined surface of the collection bin 77 to the inside of the processing drawer 78, which is convenient for unified collection and recycling.

[0049] Reference Figure 1 , Figures 8 to 9The material separation component 8 includes a second mechanical arm 81, a second mechanical arm 81 is fixed to the right part of the top wall of the fixed part of the lower conveyor belt 1, and a slide 84 is fixedly connected to the bottom wall of the second mechanical arm 81. The slide 84 is composed of three round-shaped blocks evenly fixed on the cross plate and the bottom wall of the cross plate. The bottom wall of the cross plate of the slide 84 is provided with four laser cutting heads 86 symmetrically distributed front and back with the round-shaped block in the middle of the bottom wall of the cross plate of the slide 84 as the center; the bottom wall of the second mechanical arm 81 is slidably connected to a second balance plate 82, the second balance plate 82 is an inverted U-shape, and two inverted L-shaped limit plates 83 are symmetrically fixedly connected to the bottom wall of the second balance plate 82, and three circuit board pressing blocks 85 are evenly fixed between the two inverted L-shaped limit plates 83. The three round-shaped blocks of the slide 84 are all slidably connected to the corresponding three circuit board pressing blocks 85, and an auxiliary wedge block 9 is fixed to the right part of the front top wall of the fixed part of the lower conveyor belt 1, and the rear side of the auxiliary wedge block 9 is an inclined surface.

[0050] After the laser cutting is completed, the circuit board continues to be transported to the right. After the circuit board moves to the bottom of the inverted L-shaped limit plate 83, the second mechanical arm 81 is controlled to drive the second balance plate 82 and the inverted L-shaped limit plate 83 to move downward until the inverted L-shaped limit plate 83 is close to the top wall and the left and right side walls of the return-shaped limit plate 51, and the blanking and separation component 8 presses the suction cup limit component 5, and at the same time, the return-shaped limit plate 51 can also limit the inverted L-shaped limit plate 83 to ensure that the blanking and separation component 8 is processed stably, and the bottom wall of the circuit board pressing block 85 is close to the top wall of the circuit board. Then the second mechanical arm 81 is controlled to slide left and right along the second balance plate 82, driving the slide 84 to move under the second balance plate 82, and the slide 84 slides smoothly on the outer wall of the circuit board pressing block 85, and the four laser cutting heads 86 move left and right at the same time, and laser cutting is performed on the connection between the circuit board and the residual material, thereby improving the efficiency of blanking and separation.

[0051] Reference Figure 2 , Figures 3 to 12After the processing is completed, the unloading and separating component 8 is reset, and the processed circuit board and the residual material continue to be conveyed to the right, so that the rear side of the auxiliary wedge block 9 contacts the front end of the sliding rack segment of the rack 63, and pushes the sliding rack segment of the rack 63 to slide toward the fixed segment of the rack 63, so that the gear 66 and the fixed plate 67 are reset and unlocked; when the adjusting wedge block 44 slides away from the bottom wall of the upper and lower material wedge block 3, the first reset spring 43 rebounds and drives the support frame 42 to move up and reset, and the support frame 42 drives the return-type limit plate 51 and the residual material to move up, and the residual material that moves up is separated from the circuit board on the top wall of the lower conveyor belt 1, and the positioning electric slider 59 slides and resets, leaving the adjusting wedge block 44. At the bottom of the cross bar 2 of the section rod member 53, the cross bar 2 of the adjusting rod member 53 is unlocked. At this time, under the elastic action of the second reset spring 55, the traction member 54 drives the telescopic rod 56 to reset, so that the negative pressure rod 57 moves up and resets, and the negative pressure suction cup 58 releases the adsorption of the residual material. At this time, the residual material can be transferred manually or by existing machinery to realize the separate unloading of the residual material, and the multiple circuit boards are neatly arranged and continue to move with the lower conveyor belt 1, so as to facilitate their subsequent processing, which is conducive to continuous operation and avoids the problem of low efficiency and easy damage to the circuit boards during manual splitting.

[0052] The specific operating steps of the circuit board laser cutting equipment are as follows: the lower conveyor belt 1 and the upper conveyor belt 2 are both intermittently driven, and the lower conveyor belt 1 and the upper conveyor belt 2 always maintain the same speed transmission, the front moving part of the upper conveyor belt 2 drives the support frame 42 and the return limit plate 51 to convey to the right, and the front moving part of the lower conveyor belt 1 drives the mounting part 64 to convey to the right, and the circuit board to be processed is placed at an appropriate position on the top wall of the lower conveyor belt 1, and the adjusting wedge block 44 drives the support frame 42 to move downward along with the bottom wall of the loading and unloading wedge block 3.

[0053] The return-shaped limit plate 51 moves downward accordingly. When the return-shaped limit plate 51 moves downward, the inner wall of the return-shaped limit plate 51 fits with the front and rear outer walls of the circuit board to be processed, limiting the processed circuit board from the front and rear sides; the negative pressure suction cup 58 generates suction on the top wall of the circuit board to be processed, and further limits the upper and lower positions of the circuit board to be processed; the fixed plate 67 rotates to fit with the top wall of the circuit board to be processed, so as to limit the left and right sides of the circuit board to be processed, thereby improving the efficiency of clamping and limiting, and effectively preventing the circuit board to be processed from being displaced during the processing process.

[0054] When the laser cutting head 75 performs laser cutting, the air blowing head 76 blows compressed air toward the processing part of the circuit board. The air blowing head 76 blows away the residues produced during cutting and helps cool the processing surface of the circuit board, which can reduce the carbonization phenomenon and reduce the impact of carbonization on the appearance and performance of the circuit board.

[0055] The slide 84 slides smoothly on the outer wall of the circuit board pressing block 85, and the four laser cutting heads 86 move left and right at the same time to perform laser cutting on the connection between the circuit board and the residual material, thereby improving the efficiency of material unloading and separation. After the processing is completed, the adjusting wedge block 44 drives the support frame 42 to slide and rise along the bottom wall of the upper and lower material wedge blocks 3, and the negative pressure suction cup 58 releases the adsorption of the residual material, the loading fixing component 6 is reset and unlocked, and the support frame 42 drives the suction cup limit component 5 to move upward, and the residual material moved up by the lower conveyor belt 1 is separated from the circuit board on the top wall of the lower conveyor belt 1, thereby realizing the separate unloading of the circuit board, and the circuit boards are neatly arranged to facilitate the subsequent processing, which is conducive to continuous operation.

[0056] It should be noted that, according to actual needs, multiple sets of feeding fixing components 6, up and down moving components 4 and suction cup limiting components 5 can be evenly installed on the lower conveyor belt 1 and the upper conveyor belt 2 to achieve continuous and efficient operation.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
