Technical Field

[0001] The invention relates to a layout system, in particular to a layout system integrating PCB board punching, cleaning and drying. Background Art

[0002] The integrated layout system with PCB board punching, cleaning and drying functions is designed to improve the production efficiency of PCB boards and ensure the quality and cleanliness of PCB boards during the processing process. At present, in the devices for integrated processing and production of PCB boards, such as a PCB board punching, cleaning and drying integrated device (announcement number is CN202110444806.X), only one group of products can be produced simultaneously, so the processing efficiency is low. Summary of the invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a layout system integrating PCB board punching, cleaning and drying. The production operations of multiple PCB boards can be carried out simultaneously in the production line, so as to improve the processing efficiency of PCB boards, and the entire process production line is only run through by a set of clips, that is, after the PCB boards stacked in the clips are loaded at the loading position, they can be automatically loaded into the clips again at the unloading position. The layout of the overall production line is more reasonable, and the neatness and production efficiency can also be greatly improved.

[0004] The present invention provides the following technical solutions: A layout system integrating PCB board punching, cleaning and drying, comprising a circulating material rack arranged on a table, a feeding transition line connected to the starting end of the circulating material rack, a laser punching part and a cleaning part located on both sides of the feeding transition line, and a product conveying line for realizing PCB board transportation and delivery between the laser punching part, the feeding transition line and the cleaning part. The cleaning part is also provided with at least one group of detection lines on the side away from the feeding transition line. The detection line adopts a detection linear module. A group of detection platforms are installed along a linear drive on each group of detection lines. When the detection platform moves to one end of the detection line, it is used to drive the cleaned PCB board to be photographed and detected by a detection camera, and when it moves to the other end, it is used to receive the terminal end of the circulating material rack; The starting end of the circulating material rack is provided with a loading group, which is used to hold the magazines stacked with PCB boards and connect them to the loading transition line, so as to prepare for the loading transition line to perform transition loading of PCB boards. The terminal end of the circulating material rack is provided with a unloading group, which is used to hold the empty magazines transported from the starting end of the circulating material rack to connect them to the inspection table for stacking PCB boards; the circulating material rack is provided with a belt for transporting the empty magazines at the starting end to the terminal end. The loading group and the unloading group have the same structure, both of which include a clamping unit driven by a lifting cylinder and a clamping unit for The horizontal linear module drives the clamping unit to adjust the horizontal linear position. Each time the PCB board is loaded or unloaded, the lifting cylinder is used to drive the clip to move the layer height spacing of a PCB board until the loading and unloading is completed. When the loading group is loading, the ejector driven by the ejector cylinder 1 ejects the PCB board out of the clip, and then the chuck located in the loading transition line for linear reciprocating movement clamps the extended PCB board and moves to the bottom of the product conveyor line 1 under the drive of its loading linear module to wait for the adsorption and positioning of the product conveyor line 1. The loading group and the ejector driven by the ejector cylinder 1 The structure of the driven ejector pin ejecting the PCB board out of the clip has been disclosed in the patent applied for by the company before, which belongs to the prior art and will not be described here. The difference is that by adding the same unloading group and circulating material rack, it cooperates with the loading group to realize that a group of full clips of PCB boards to be processed can pass through the circulating material rack to reach the end to reload the processed PCB boards. The whole cycle only needs one group of clips to form a closed loop of processing. The system layout structure forming the closed loop is also highly integrated and neat, and the production efficiency can also be improved. The clamping head clamps the end of the PCB board extending out of the clip under the drive of the clamping cylinder, and its mounting end is installed on the driving end of the adjusting cylinder. The adjusting cylinder is used to adjust the lifting of the clamping head to adapt the height to clamp the PCB board to the receiving rail groove of the feeding transition line. A conveyor belt driven by a conveying motor is arranged on one side of the feeding transition line. The mounting end of the adjusting cylinder is installed on the conveyor belt, and then moves back and forth in a straight line with the conveyor belt. A transfer plate is also arranged on the receiving rail groove. The transfer plate is driven to rotate by the transfer cylinder and is used for pressing on the PCB board above the receiving rail groove. The laser drilling section includes at least one set of slide rails, and two sets of material receiving platforms are slidably installed on each set of slide rails. Each set of material receiving platforms corresponds to a set of punching stations. After the PCB board is delivered to the material receiving platform from the loading transition line via the product conveyor line 1 and completed laser drilling at the punching station, it is then delivered to the cleaning section for cleaning and drying by the product conveyor line 1. A set of product conveyor line 2 is also arranged across the cleaning section and the inspection line. The product conveyor line 2 is used to realize the transportation transition of the PCB board products between the cleaning section and the inspection line. At this point, in the present invention, a group of PCB boards to be processed with the circulating material rack as the starting point are transferred to the receiving platform via the loading group, the loading transition line, and the product conveyor line 1 in sequence. The receiving platform drives the PCB boards to the punching station for punching, and after the punching is completed, it is again conveyed by the product conveyor line 1 to the cleaning part for cleaning and drying, and then conveyed by the product conveyor line 2 to the detection line for completion of detection, and then moves to dock with the empty clip of the unloading group. The empty clip is the clip after the loading of the loading group is completed, and it is conveyed back to the unloading group via the circulating material rack for re-coding. At this point, the transformation of a group of clips starting with the product to be processed and ending with the completed product can be realized, with a higher degree of automation and more convenience.

Each time the PCB board is loaded or unloaded, the lifting cylinder 81 is used to drive the clip to move the layer height spacing of the PCB board accordingly until the loading and unloading is completed. When the loading group 8 is loading, the ejector pin 85 driven by the ejector cylinder 84 ejects the PCB board out of the clip, and then the chuck 21 located in the loading transition line 2 for linear reciprocating clamps the extended PCB board and moves to the bottom of the product conveyor line 5 under the drive of its loading linear module to wait for the adsorption and positioning of the product conveyor line 5. The loading group 8 and the ejector pin 85 driven by the ejector cylinder 84 eject the PCB board out of the clip, and then the chuck 21 located in the loading transition line 2 for linear reciprocating clamps the extended PCB board and moves to the bottom of the product conveyor line 5 under the drive of its loading linear module to wait for the adsorption and positioning of the product conveyor line 5. The structure of the ejector pin 85 driven by the 84 to eject the PCB board out of the clip has been disclosed in the patent applied for by the company before, which belongs to the prior art and will not be described here. The difference is that by adding the same unloading group 10 and the circulating material rack 1, it cooperates with the loading group 8 to realize that a group of full clips of PCB boards to be processed can pass through the circulating material rack 1 to reach the end to reload the processed PCB boards. The whole cycle only needs one group of clips to form a closed loop of processing. The system layout structure of the closed loop is also highly integrated and neat, and the production efficiency can be greatly improved. The chuck 21 is in the clamping The end of the PCB board extending out of the clip is clamped under the drive of the cylinder 22, and its mounting end is installed on the driving end of the adjustment cylinder 23. The adjustment cylinder 23 is used to adjust the lifting and lowering of the clamp 21 to adapt the height to clamp the PCB board to the receiving rail groove 24 of the feeding transition line 2. A conveyor belt 26 driven by a conveying motor 25 is arranged on one side of the feeding transition line 2. The mounting end of the adjustment cylinder 23 is installed on the conveyor belt 26, and then moves back and forth in a straight line with the conveyor belt 26. A transfer plate 27 is also arranged on the receiving rail groove 24. The transfer plate 27 is driven to rotate by the transfer cylinder 28 and is used for crimping on the PCB board above the receiving rail groove 24. The laser drilling section 3 includes at least one set of slide rails 31, and two sets of material receiving platforms 32 are slidably installed on each set of slide rails 31. Each set of material receiving platforms 32 corresponds to a set of punching stations 33. After the PCB board is delivered to the material receiving platform 32 by the loading transition line 2 via the product conveying line 1 5 and the laser punching machine is completed at the punching station 33, it is then delivered to the cleaning section 4 by the product conveying line 1 5 for cleaning and drying. A set of product conveying lines 2 9 is also arranged across the cleaning section 4 and the testing line 6. The product conveying lines 2 9 are used to realize the transportation transition of the PCB board products between the cleaning section 4 and the testing line 6. At this point, in the present invention, a group of PCB boards to be processed with the circulating material rack 1 as the starting point are transferred to the receiving platform 32 via the loading group 8, the loading transition line 2, and the product conveyor line 5 in sequence. The receiving platform 32 drives the PCB boards to the punching station 33 for punching, and after the punching is completed, it is again conveyed by the product conveyor line 5 to the cleaning part 4 for cleaning and drying, and then conveyed by the product conveyor line 29 to the detection line 6 to complete the detection, and then moved to dock with the empty clip of the unloading group 10. The empty clip is the clip after the loading of the loading group 8 is completed. It is conveyed back to the unloading group 10 through the circulating material rack 1 for coding again. At this point, the transformation of a group of clips starting with the product to be processed and ending with the completed product can be realized, with a higher degree of automation and more convenience. The layout of the overall production line is also more reasonable, and the neatness and production efficiency can be greatly improved.

[0016] Example 2 A layout system integrating PCB board punching, cleaning and drying. In this embodiment, it is further limited based on Example 1, wherein the product conveyor line 5 includes a transition linear module 51 and a transition frame 52 installed at the driving end of the linear module. Two groups of transition suction cups 54 corresponding to the lifting and lowering driven by a downward pressure cylinder 53 are installed on the transition frame 52. The two groups of transition suction cups 54 are used to adsorb the PCB board after punching and place the PCB board to be processed when sliding to the top of the material receiving platform 32, so as to ensure that each time the transition linear module 51 slides once, two different operations can be completed to improve the processing efficiency. The laser drilling machine used for laser drilling at the punching station 33 and the material receiving platform 32 used for adsorbing and positioning the PCB board products to be received are both existing technologies and will not be described in detail here.

[0017] The cleaning part 4 includes a cleaning tank 41 and at least one cleaning material table 42 installed in the cleaning tank 41. Two groups of clamping claw units 43 are installed at both ends of the cleaning material table 42. A clamping push cylinder 44 is also hingedly installed on the bottom side. The clamping push cylinder 44 is used to drive the clamping claw unit 43 to rotate so as to be crimped and positioned on the PCB board of the cleaning material table 42. The cleaning material table 42 is installed at the driving end of a group of driving cylinders 45. The driving cylinders 45 are positioned on a group of rotating shafts 46 through the material table mounting plate. The two ends of the rotating shafts 46 are mounted in the cleaning tank 41 and driven to rotate by a rotating motor 47. Therefore, after the cleaning material table 42 receives the product, the clamping claw unit 43 is pressed on both ends of the product under the drive of the clamping and pushing cylinder 44, and then the rotating shaft 46 can drive the cleaning material table 42 to rotate 180°, and then the driving cylinder 45 can drive the cleaning material table 42 to be pressed down so that the product enters the cleaning tank 41 for cleaning.

[0018] Opening and closing push cylinders 48 are also provided on both sides of the cleaning tank 41, and two sets of opposite opening and closing doors 49 are slidably installed on the top side. The two sets of opening and closing doors 49 are used to close under the push of the opening and closing push cylinders 48 to seal the cleaning tank 41 during cleaning, making the cleaning environment neater.

[0019] A set of right-angle plates 410 are also slidably installed on one side of the cleaning tank 41 close to the detection line 6. A wiping sponge 411 is installed on one end of the right-angle plate 410 extending into the cleaning tank 41, and a drying machine 412 is installed on the other end extending out of the cleaning tank 41. The right-angle plate 410 moves back and forth along the notch of the cleaning tank 41 in a straight line under the drive of the drying linear module 413. After the product is cleaned, the product conveyor line 29 drives the product to continue to move toward the detection line 6 and when it passes over the wiping sponge 411, the product conveyor line 29 then drives the product down until it contacts the wiping sponge 411, and then starts the drying linear module 413 to drive the wiping sponge 411 to move back and forth along the product straight line to complete wiping the cleaning liquid on the back of the product, and then drives the product to rise and continue to move to above the dryer 412 and then stays still. The dryer 412 then moves back and forth along the notch of the cleaning tank 41 in a straight line under the drive of the drying linear module 413 to dry the product above.

[0020] The product conveying line 29 includes a transition linear module 292 on a gantry 291, and a transition frame 293 installed at the driving end of the linear module 2. A transition suction cup 295 driven to rise and fall by a corresponding lower pressure cylinder 294 is installed on the transition frame 293. The transition suction cup 295 is used to adsorb and fix the PCB board after cleaning when sliding to the top of the cleaning material table 42. The number and spacing of the transition suction cups 295 are the same as the number and spacing of the cleaning material table 42 and the detection line 6, so as to ensure that the corresponding transfer of multiple pairs of products can be completed at the same time to improve the processing efficiency.

[0021] A set of dryers 96 are arranged on the side of the gantry 91 away from the transition linear module 92. When the inspection table 7 receives the PCB board delivered by the transition suction cup 95 and moves toward one end of the inspection camera 11, the dryer 96 is used to further spray and dry the PCB board passing below. A right-angled notch 71 is provided on both sides of the testing platform 7, and the PCB board is placed on the testing platform 7, and its side edges are suspended above the right-angled notch 71. Rotating pressing plates 72 are also installed on both sides of the testing platform 7. The rotating pressing plates 72 are used for crimping and positioning on both sides of the PCB board under the drive of the rotating motor 73. Two groups of docking rails 74 are also arranged between the testing line 6 and the blanking group 10. The two groups of docking rails 74 have docking grooves 75 on the opposite sides, which are docked at the two groups of right-angled notch grooves 71, and are used to move the testing platform 7 toward the blanking group 10. When moving upward, the two side edges of the PCB board are passed through the docking groove 75, and the docking rail 74 is installed on the driving end of a group of lifting and adjusting cylinders 76. A group of pushing grooves 77 are also installed at the end of the testing platform 7. The lifting and adjusting cylinders 76 are used to adjust the height between the PCB board to adapt to the clip in the unloading group 10 and the pushing groove 77. The pushing groove 77 moves back and forth in a straight line with the testing platform 7 to push the PCB board in the docking groove 75 to be placed in the unloading group 10. At this point, the operation of filling the PCB board into the clip again after the test can be realized, and the continuity and compactness of the arrangement are better.

[0022] The two groups of docking rails 74 are correspondingly installed on two groups of sliding blocks 78. The sliding blocks 78 are slidably installed on the mounting plate at the driving end of a group of lifting and adjusting cylinders 76, and are driven by a group of screw rods 79 to perform reverse movement. At this point, the spacing between the two groups of docking rails 74 can be adjusted to adapt to the docking of PCB boards of different widths. The lifting and adjusting cylinders 76 are installed on the driving end of a group of adjustment linear modules 710. There are at least two groups of detection lines 6. The adjustment linear modules 710 are arranged across the top of the detection lines 6 to drive the two groups of docking rails 74 to dock the detection tables 7 on different detection lines 6.

[0023] The working principle of the present invention is as follows: In the present invention, a group of PCB boards to be processed with the circulating material rack 1 as the starting point are transferred to the receiving platform 32 via the feeding group 8, the feeding transition line 2, and the product conveying line 1 5 in sequence. The receiving platform 32 drives the PCB board to the punching station 33 for punching, and after the punching is completed, it is again transported by the product conveying line 1 5 to the cleaning part 4 for cleaning and drying, and then transported by the product conveying line 2 9 to the testing line 6 for testing, and then moves to dock with the empty magazine of the unloading group 10, and the empty magazine is After the loading group 8 has finished loading, the clips are transported back to the unloading group 10 through the circulating material rack 1 for re-stack. At this point, the start of a group of clips can be the product to be processed and the end can be the finished product. The automation is higher and more convenient. The layout of the overall production line is more reasonable, and the neatness and production efficiency can be greatly improved. Among them, when the cleaning material table 42 receives the product, the clamping claw unit 43 is pressed at both ends of the product under the drive of the clamping push cylinder 44 to realize the positioning of the product, and then the rotating shaft 46 drives the cleaning material The table 42 rotates 180 degrees, and the driving cylinder 45 drives the cleaning material table 42 downward to make the product enter the cleaning tank 41 for cleaning. After the product is cleaned, the product conveying line 29 drives the product to continue to move toward the detection line 6 and when it passes above the wiping sponge 411, the product conveying line 29 then drives the product down to contact with the wiping sponge 411, and then starts the drying linear module 413 to drive the wiping sponge 411 to go back and forth along the product straight line to complete the wiping of the cleaning liquid on the back of the product, and then drives the product to rise and continue to move to the dryer 4 12 is placed on top, and the dryer 412 is then driven by the drying linear module 413 to move back and forth in a straight line along the notch of the cleaning tank 41 to dry the product above. At this point, the entire process of the product entering the cleaning tank 41 for cleaning, wiping and drying can be completed, with a higher degree of automation and greater convenience. In the present invention, a docking rail 74 is used to dock the inspection table 7 to achieve the transition of the PCB board, and then the transition of the product between the docking rail 74 and the unloading group 10 is achieved by pushing the card slot 77, with better continuity and compactness.
