Description

Technical Field

[0001] This utility model relates to a laser marking production line, and more particularly to an automated laser marking production line for a paper-layered PCB board. Background Technology

[0002] Laser marking machines are mainly used in the PCB industry to mark traceable information such as barcodes, QR codes, characters, and graphics on circuit boards. They offer high marking accuracy, speed, stable performance, and simple operation. They can print various complex patterns, texts, QR codes, and other content, meeting the high-quality marking requirements of the current PCB industry. However, in existing technologies, automated laser marking production lines for PCBs with paper separation are generally linear production lines, which require a large footprint, as shown in the patent for a fully automatic marking machine with automatic traceability (publication number CN210997053U). Utility Model Content

[0003] To solve the above-mentioned technical problems, the purpose of this utility model is to provide an automated laser marking production line for PCB boards with paper separation and layering. By adopting a rotary conveyor in conjunction with circumferentially arranged processing equipment, the overall footprint of the equipment is reduced, resulting in better overall space utilization and higher processing efficiency.

[0004] This utility model provides the following technical solution:

[0005] An automated laser marking production line for PCBs with paper separation includes an indexing plate assembly for circumferential rotation, and a feeding assembly, a laser marking assembly, a visual inspection assembly, and a unloading assembly sequentially arranged around the indexing plate assembly. Four positioning units are evenly distributed circumferentially on the indexing plate assembly, which simultaneously align the feeding assembly, laser marking assembly, visual inspection assembly, and unloading assembly to coordinate the feeding, marking, inspection, and unloading operations of the PCB products. A feeding transfer assembly is arranged between the feeding assembly and the indexing plate assembly, and the feeding transfer assembly includes components for adsorbing and transferring paper separation material from the feeding assembly. The feeding paper transfer section to the feeding paper separation position and the feeding product transfer section for adsorbing PCB board products transferred from the feeding group to the positioning section are provided. A feeding transfer group is arranged between the feeding group and the indexing plate group. The feeding transfer group includes a feeding product transfer section for adsorbing PCB board products transferred from the positioning section to the feeding group and a feeding paper transfer section for adsorbing paper separators on the feeding paper separation position and transferring them to the PCB board products on the feeding group. The laser marking group is used to laser mark the PCB board products on the positioning section after they have been rotated into place. The visual imaging and inspection group is used to photograph and inspect the marked PCB board products.

[0006] At this point, the PCB products stacked by the feeding group are arranged with spacers and PCB products stacked alternately. The feeding spacer transfer unit first picks up the spacers from the feeding group and transfers them to the feeding paper separating position. Then, the feeding product transfer unit picks up the PCB products from the feeding group and transfers them to the positioning unit that has been rotated into place. The PCB products on the positioning unit rotate 90° each time by the indexing plate, so that they can pass through the laser marking group, the visual imaging inspection group, and the unloading group in sequence. Laser marking is completed in the laser marking group. The visual imaging inspection group completes the visual imaging inspection. In the unloading group, the unloading product transfer unit picks up the PCB board products and transfers them from the positioning unit to the unloading group. Then, the unloading paper transfer unit picks up the paper separators on the unloading paper separation position and transfers them to the PCB board products in the unloading group. This completes the processing and unloading of one layer of products. The whole process is relatively smooth and can make good use of space. Both loading and unloading can be stacked. Subsequent replacements can directly stack the loading and unloading, so the processing efficiency is also higher.

[0007] Preferably, the indexing plate group includes a turntable driven to rotate by a rotary motor, four positioning parts arranged at 90° intervals around the turntable, and each positioning part includes a suction cup mounted on the turntable, which is used to adsorb and fix the PCB board product placed in place.

[0008] Preferably, the feeding group includes a feeding bottom tray, a feeding lifting module, a feeding lifting push plate, and a feeding base. The feeding bottom tray is used to horizontally stack PCB boards to be separated into layers, and its bottom is connected to the feeding lifting push plate. The feeding lifting module is installed on the feeding base, and its drive end is connected to the feeding lifting push plate to drive the feeding bottom tray to rise and fall, in order to cooperate with the adsorption operation of the feeding transfer group.

[0009] Preferably, a feeding and separating paper section is arranged above the feeding base, parallel to the feeding bottom tray. The feeding and separating paper section includes a second feeding bottom tray, a second feeding lifting module, and a second feeding lifting push plate. The second feeding bottom tray is used to horizontally stack the separated paper after layering. Its bottom is connected to the second feeding lifting push plate. The second feeding lifting module is installed on the feeding base, and its driving end is connected to the second feeding lifting push plate to drive the second feeding bottom tray to rise and fall, so as to cooperate with the feeding and separating paper transfer part to adsorb the separating paper on the PCB board product onto the second feeding bottom tray for stacking.

[0010] Preferably, the loading platform is also provided with a straightening structure, which is used to straighten the stacked items on the loading bottom tray one and loading bottom tray two.

[0011] Preferably, the straightening structure includes two sets of lead screw nuts driven by lead screws to move in opposite directions. Each set of lead screw nuts is equipped with a set of crossbars. Each set of crossbars is equipped with two sets of transverse straightening columns corresponding to the first and second bottom loading plates, respectively. The two sets of transverse straightening columns, distributed opposite each other, move towards each other under the drive of the lead screws to abut against the left and right sides of the stacked items to perform straightening operations on the left and right sides of the stacked items. A longitudinal drive cylinder is also installed at the bottom of the loading base. The drive end of the longitudinal drive cylinder is connected to a mounting plate for installing the longitudinal straightening columns. The two sets of longitudinal straightening columns pass through the guide groove of the loading base and are respectively placed on the front side of the first and second bottom loading plates. A set of side stops is also distributed on the rear side of the first and second bottom loading plates. The longitudinal straightening columns are driven by the longitudinal straightening columns and cooperate with the side stops to limit the stacked items on the front and rear sides to perform straightening operations on the left and right sides of the stacked items.

[0012] Preferably, the unloading group has the same structure as the loading group.

[0013] Preferably, the laser marking group includes a laser marking machine for laser marking PCB products that have been rotated into position, and the visual imaging and inspection group includes a camera for photographing and inspecting PCB products that have been rotated into position. This is prior art and will not be described in detail here.

[0014] Preferably, the loading product transfer section and the unloading product transfer section have the same structure, and both include a mounting frame, a product transfer horizontal module, a product transfer vertical module, a product transfer frame, and a product adsorption head. The product transfer frame is equipped with a product adsorption head for adsorbing PCB board products, which is installed at the drive end of the product transfer vertical module. The product transfer vertical module is installed at the drive end of the product transfer horizontal module to drive the PCB board products to rise and fall. The product transfer horizontal module is positioned on the mounting frame to drive the PCB board products back and forth between the loading group and the indexing plate group or between the indexing plate group and the unloading group.

[0015] Preferably, the feeding paper transfer section has the same structure as the unloading paper transfer section, and is respectively installed on the mounting frame of the feeding product transfer section and the unloading product transfer section, including a mounting plate fixed on the corresponding mounting frame, a paper longitudinal module installed on the mounting plate, a paper transverse transfer section installed on the driving end of the paper longitudinal module, and a paper suction head installed on the paper transverse transfer section.

[0016] The longitudinal module of the paper separator is used to drive the paper separator adsorption head with the paper separator adsorbed to move up and down longitudinally through the paper separator lateral transfer part. The paper separator lateral transfer part is used to drive the paper separator adsorption head with the paper separator adsorbed to move laterally. This paper separator lateral transfer part can be a linear module in any lateral direction, or it can be a structure in which a motor drives two sets of connecting rods to flip. The end of the connecting rod is connected to a set of longitudinal rods, so that the mounting frame of the paper separator adsorption head is installed at the bottom end of the longitudinal rods. When the motor rotates 180°, it can simultaneously drive the adsorption head to move laterally by the length of the two sets of connecting rods in the lateral direction, while ensuring that the longitudinal position remains unchanged.

[0017] The beneficial effects of this utility model are as follows: In the production line of this utility model, the feeding group feeds stacked PCB products, which are alternately stacked with partition paper. The partition paper transfer part first adsorbs the partition paper on the feeding group and transfers it to the feeding paper separating position. Then, the feeding product transfer part adsorbs the PCB products and transfers them from the feeding group to the positioning part that has been rotated into position. The PCB products on the positioning part are rotated 90° each time by the indexing plate, so that they can pass through the laser marking group, the visual imaging inspection group, and the unloading group in sequence. The coding group completes laser marking, the visual imaging inspection group completes visual imaging inspection, and in the unloading group, the unloading product transfer unit picks up the PCB board product and transfers it from the positioning unit to the unloading group. Then, the unloading paper transfer unit picks up the paper separator on the unloading paper separation position and transfers it to the PCB board product in the unloading group. This completes the processing and unloading of one layer of product. The whole process is very smooth and can make good use of space. The loading and unloading can be stacked. Subsequent replacements can directly stack the loading and unloading, so the processing efficiency is also higher. Attached Figure Description

Detailed Implementation

[0028] like Figure 1-7 As shown, an automated laser marking production line for paper-separated PCB boards includes, in this embodiment, an indexing plate group 1 for circumferential rotation and a feeding group 2, a laser marking group 3, a visual imaging and detection group 4, and a unloading group 5 arranged sequentially around the indexing plate group 1.

[0029] Four sets of positioning parts are evenly distributed along the circumference of the indexing plate group 1. The four sets of positioning parts are used to simultaneously align the loading group 2, the laser marking group, the visual photography inspection group 4, and the unloading group 5 to cooperate in the loading, marking, inspection, and unloading of PCB products. The unloading group 5 has the same structure as the loading group 2.

[0030] A feeding transfer group 6 is arranged between the feeding group 2 and the indexing plate group 1. The feeding transfer group 6 includes a feeding paper transfer part for adsorbing and transferring the paper separator on the feeding group 2 to the feeding paper separation position, and a feeding product transfer part for adsorbing and transferring the PCB board products from the feeding group 2 to the positioning part. A feeding transfer group 7 is arranged between the unloading group 5 and the indexing plate group 1. The feeding transfer group 7 includes a feeding product transfer part for adsorbing and transferring the PCB board products from the positioning part to the feeding group 5, and a feeding paper separator transfer part for adsorbing and transferring the paper separator on the feeding paper separation position to the PCB board products in the feeding group 5. A laser marking group is used to laser mark the PCB board products on the positioning part that has been rotated into place. A visual imaging and inspection group 4 is used to photograph and inspect the marked PCB board products.

[0031] At this point, the PCB board products stacked in the feeding group 2 are loaded with paper dividers. The paper divider transfer unit first picks up the paper dividers on the feeding group 2 and transfers them to the paper separating position. Then, the product transfer unit picks up the PCB board products and transfers them from the feeding group 2 to the positioning unit that has been rotated into place. The PCB board products on the positioning unit rotate 90° each time by the indexing plate, so that they can pass through the laser marking group 3, the visual imaging inspection group 4, and the unloading group 5 in sequence. Laser marking is completed in the laser marking group 3. Visual inspection is completed in visual inspection group 4. In unloading group 5, the PCB board product is transferred from the positioning unit to unloading group 5 by the unloading product transfer unit. Then, the unloading paper transfer unit picks up the paper separator on the unloading paper separator and transfers it to the PCB board product in unloading group 5. This completes the unloading of one layer of product. The whole process is relatively smooth and can make good use of space. Both loading and unloading can be stacked. Subsequent replacements can directly stack the loading and unloading, so the processing efficiency is also higher.

[0032] The indexing plate assembly 1 includes a turntable 11 driven to rotate by a rotary motor. Four positioning parts are arranged at 90° intervals around the turntable 11, and each positioning part includes a suction cup 12 mounted on the turntable 11. The suction cup 12 is used to adsorb and fix the PCB board product placed in the position.

[0033] The loading assembly 2 includes a loading bottom tray 21, a loading lifting module 22, a loading lifting push plate 23, and a loading base 24. The loading bottom tray 21 is used to horizontally stack PCB boards to be separated into layers. Its bottom is connected to the loading lifting push plate 23. The loading lifting module 22 is installed on the loading base 24. Its drive end is connected to the loading lifting push plate 23 to drive the loading bottom tray 21 to rise and fall, in order to cooperate with the adsorption operation of the loading transfer assembly 6.

[0034] Above the feeding base 24, there is also a feeding paper separation position arranged in parallel with the feeding bottom tray. The feeding paper separation position includes a second feeding bottom tray 25, a second feeding lifting module 26, and a second feeding lifting push plate 27. The second feeding bottom tray 25 is used to horizontally stack the separated paper after layering. Its bottom is connected to the second feeding lifting push plate 27. The second feeding lifting module 26 is installed on the feeding base 24. Its drive end is connected to the second feeding lifting push plate 27 to drive the second feeding bottom tray 25 to rise and fall, so as to cooperate with the feeding paper separation transfer part to adsorb the paper separation on the PCB board product onto the second feeding bottom tray 25 for stacking.

[0035] A straightening structure is also arranged on the feeding platform 24. The straightening structure is used to straighten the stacked items on the feeding bottom support plate 1 21 and feeding bottom support plate 25.

[0036] The straightening structure includes two sets of lead screw nuts driven in opposite directions by lead screw 28. Each set of lead screw nuts is equipped with a set of crossbars 29. Each crossbar 29 has two sets of transverse straightening columns 210, corresponding to the first and second bottom support plates 21 and 25 respectively. The two sets of oppositely distributed transverse straightening columns 210 move towards each other under the drive of lead screw 28 to abut against the left and right sides of the stacked items for straightening operations on both sides. A longitudinal drive cylinder 211 is also installed at the bottom of the loading base 24. A mounting plate 66 for mounting longitudinal alignment columns 212 is connected to the drive end of the drive cylinder 211. The two sets of longitudinal alignment columns 212 pass through the guide groove of the loading base 24 and are respectively placed on the front side of the loading bottom support plate 1 21 and the loading bottom support plate 25. A set of side stops 213 are also distributed on the rear side of the loading bottom support plate 1 21 and the loading bottom support plate 25. The longitudinal alignment columns 212 are driven by the longitudinal alignment columns 212 and cooperate with the side stops 213 to limit the longitudinal alignment columns 212 to the front and rear sides of the stacked items, so as to perform alignment operations on the left and right sides of the stacked items.

[0037] The laser marking group includes a laser marking machine for laser marking PCB products that have been rotated into position, and the visual imaging inspection group 4 includes a camera for photographing and inspecting PCB products that have been rotated into position. This is existing technology and will not be described in detail here.

[0038] The loading and unloading product transfer sections have the same structure, and both include a mounting frame 61, a product transfer horizontal module 62, a product transfer vertical module 63, a product transfer frame 64, and a product suction head 65. The product transfer frame 64 is equipped with a product suction head 65 for adsorbing PCB board products. It is installed on the drive end of the product transfer vertical module 63, which is installed on the drive end of the product transfer horizontal module 62 to drive the PCB board products to rise and fall. The product transfer horizontal module 62 is positioned on the mounting frame 61 and is used to drive the PCB board products back and forth between the loading group 2 and the indexing plate group 1 or between the indexing plate group 1 and the unloading group 5.

[0039] The feeding paper transfer section and the unloading paper transfer section have the same structure and are respectively installed on the mounting frame 61 of the feeding product transfer section and the unloading product transfer section. The paper transfer section includes a mounting plate 66 fixed on the corresponding mounting frame 61, a paper transfer longitudinal module 67 installed on the mounting plate 66, a paper transfer lateral transfer section 68 installed on the driving end of the paper transfer longitudinal module 67, and a paper transfer adsorption head 69 installed on the paper transfer lateral transfer section 68.

[0040] The longitudinal module 67 is used to drive the paper-adsorbing head 69, which adsorbs the paper, to move up and down longitudinally via the transverse transfer part 68. The transverse transfer part 68 is used to drive the paper-adsorbing head 69 to move laterally. This transverse transfer part 68 can be a linear module in any transverse direction, or it can be a structure in which two sets of connecting rods are flipped by a motor. The end of the connecting rod is connected to a longitudinal rod, so that the mounting bracket 61 of the paper-adsorbing head 69 is installed at the bottom of the longitudinal rod. When the motor rotates 180°, it can simultaneously drive the adsorbing head to move laterally by the length of the two sets of connecting rods in the transverse direction, while ensuring that the longitudinal position remains unchanged.

[0041] The working principle of this utility model is as follows: In the production line of this utility model, the feeding group 2 feeds stacked PCB products, which are alternately stacked with partition paper. The partition paper transfer part first adsorbs the partition paper on the feeding group 2 and transfers it to the feeding paper separation position. Then, the feeding product transfer part adsorbs the PCB products and transfers them from the feeding group 2 to the positioning part that has been rotated into position. The PCB products on the positioning part are rotated 90° each time by the indexing plate, so that they can pass through the laser marking group 3, the visual imaging inspection group 4, and the unloading group 5 in sequence. The marking group 3 completes laser marking, the visual imaging inspection group 4 completes visual imaging inspection, and in the unloading group 5, the unloading product transfer unit picks up the PCB board product and transfers it from the positioning unit to the unloading group 5. Then, the unloading paper transfer unit picks up the paper separator on the unloading paper separation position and transfers it to the PCB board product in the unloading group 5. This completes the processing and unloading of one layer of product. The whole process is very smooth and can make good use of space. The loading and unloading can be stacked. Subsequent replacements can directly stack the loading and unloading, so the processing efficiency is also higher.
