[0002] The main function of the PCBA plate placing machine is to place the small PCBA after cutting and splitting into panels in a designated position or container such as a blister tray according to certain rules and requirements. This process usually includes multiple steps such as detection, positioning, handling, and placement. The plate placing machine can greatly improve the production efficiency and placement accuracy of PCBA, while reducing the error and labor intensity of manual operation. In the design process of electronic products, the design layout of PCBA is a crucial step. Accurate plate placing can ensure the reliability and stability of the circuit, avoid interference and signal noise, and improve the performance and quality of the product. However, even after dust removal, there is still a lot of dust left on the small PCBA after cutting and splitting. It is difficult for the existing PCBA plate placing machine to remove dust again.

The first synchronous belt module 42 drives the first slide 43, and the second synchronous belt module 45 drives the raising block 46, so that the two PCBA fixtures 48 move alternately, one high and one low, to transport PCBA in batches, which is beneficial to improving the transportation efficiency; the raising block 46 cooperates with the lifting cylinder 44 to avoid the collision of the two PCBA fixtures 48. When the secondary dust removal mechanism 3 cooperates with the PCBA fixture 48 of the lifting cylinder 44 for dust removal, the lifting cylinder 44 is used to lift the PCBA fixture 48 so that the secondary dust removal mechanism 3 cooperates with the PCBA fixture 48 for dust removal.

At the same time, the X-axis synchronous belt linear module 32 drives the ion wind rod 33 to move along the X-axis direction. The ion wind rod 33 removes static electricity from the PCBA on the PCBA fixture 48 to separate the dust from the PCBA and be suctioned by the telescopic dust suction assembly 36, so as to further remove the dust attached to the PCBA and improve the dust removal effect.

[0031] Furthermore, the lifting drive assembly 34 includes two first lifting cylinders 341 respectively connected to the two inner side walls of the gantry bracket 31, and a second support 342 connected to the output end of the first lifting cylinder 341, and the end of the cover plate 35 is connected to the top of the second support 342; the cover plate 35 is provided with a plurality of first clearance holes 12 for the ion wind rod 33 to remove static electricity from the PCBA on the PCBA fixture 48.

A second makeshift through hole 13 is provided on one side of the gantry bracket 31 for the dust hood 363 to extend into the gantry bracket 31 and communicate with the fixture. The dust hood 363 is used to cooperate with the fixture opening 11 for use in communication. The double guide rod cylinder 362 is used to drive the dust hood 363 to pass through the second clearance hole 13, extend into the gantry bracket 31 and communicate with the fixture opening 11 of the PCBA fixture 48. At this time, the dust suction port 10, the fixture inner cavity, the fixture opening 11, the dust hood 363 and the vacuum suction pipe 364 are connected in sequence to suck away the dust on the PCBA.

[0033] Furthermore, the blister tray lifting silo 6 includes an XZ axial transfer mechanism 61 connected to the top of the machine 1, a blister tray limiting frame 62 connected to the bottom of the machine 1, a servo screw module 63 connected to one side of the machine 1, a bracket 64 connected to the output end of the servo screw module 63 and extending into the blister tray limiting frame 62, a sub-disc supporting mechanism 65 connected to the top of both sides of the blister tray limiting frame 62, and a blister tray positioning mechanism 66 connected to the sub-disc supporting mechanism 65 away from the side of the servo screw module 63, the servo screw module 63 is used to drive the bracket 64 to rise and fall, the bracket 64 is used to support the stacked blister trays, the sub-disc supporting mechanism 65 cooperates with the XZ axial transfer mechanism 61 to separate and support independent blister trays from the stacked blister trays, and the XZ axial transfer mechanism 61 is used to move the blister trays along the XZ axial direction. When the blister tray lifting bin 6 is used, the stacked blister trays are supported by the bracket 64, and the servo screw module 63 drives the bracket 64 to rise until the top blister tray is flush with the sub-tray support mechanism 65, and the sub-tray support mechanism 65 separates the top independent blister tray from the stacked blister trays, and the remaining blister trays descend with the servo screw module 63, and then the XZ axial transfer mechanism 61 drives the independent blister tray to rise and then descend and release the blister tray, and at the same time, the sub-tray support mechanism 65 is used to support the blister tray, and then the blister tray positioning mechanism 66 is used to position the blister tray, and the PCBA can be swung onto the blister tray with the help of the multi-axis transfer mechanism 5 to avoid the stacked blister trays easily causing the PCB containing groove in the top blister tray to tighten and deform, which is more conducive to the swing operation of the multi-axis transfer mechanism 5, and is particularly suitable for the blister tray feeding of small PCBA.

[0034] Furthermore, the XZ axial transfer mechanism 61 includes an X-axial linear module 611 connected to the top of the machine 1, a first bracket 612 connected to the output end of the X-axial linear module 611, a Y-axis extension frame 613 fixedly connected to the top of the first bracket 612, a second lifting cylinder 614 connected to the end of the Y-axis extension frame 613 away from the first bracket 612, a fixed frame 615 connected to the output end of the second lifting cylinder 614, and a plurality of first suction cups 616 fixedly connected to the fixed frame 615, and the plurality of first suction cups 616 cooperate to adsorb blister discs. The X-axis linear module 611 drives the first bracket 612, the Y-axis extension frame 613, the second lifting cylinder 614, the fixed frame 615 and the first suction cup 616 to move along the X-axis direction. On the one hand, when the blister disc is swung after separation, the X-axis linear module 611 drives the first bracket 612 away from the blister disc limiting frame 62 to avoid obstructing the swinging of the disc. On the other hand, after the swinging of the disc is completed, multiple first suction cups 616 work together to absorb the blister disc, and then transfer the blister disc out of the blister disc limiting frame 62 so that the next blister disc can continue to operate.

[0035] Furthermore, the sub-disc supporting mechanism 65 includes two third supports 651 respectively connected to the tops of both sides of the blister disk limiting frame 62, a first telescopic cylinder 652 fixedly connected to the bottom of the third support 651, a second bracket 653 connected to the output end of the first telescopic cylinder 652 and passing through the third support 651, a second telescopic cylinder 654 connected to the top of the second bracket 653, a linear bearing seat 655 fixedly connected to the top of the third support 651, a support shaft 656 slidably matched with the linear bearing seat 655, and a support plate 657 connected to the output end of the second telescopic cylinder 654 and the support shaft 656. The third support 651 is provided with a third make way hole (not shown in the figure) for the first telescopic cylinder 652 to drive the second bracket 653 to move, and the two support plates 657 cooperate to support the blister disk.

[0036] Furthermore, the tops of both sides of the blister tray limiting frame 62 are provided with clearance grooves 14 for the support plate 657 to extend into the blister tray limiting frame 62; the blister tray positioning mechanism 66 includes a fixed pad 661 connected to the side of the third support 651 away from the servo screw module 63, a third telescopic cylinder 662 connected to the top of the fixed pad 661, and a right-angle push plate 663 connected to the output end of the third telescopic cylinder 662, and the third telescopic cylinder 662 and the right-angle push plate 663 cooperate to push the blister tray to the end angle of the blister tray limiting frame 62 away from the right-angle push plate 663 for abutment and positioning, which is more conducive to the swinging operation of the multi-axis transfer mechanism 5. The support plate 657 extends into the blister tray limiting frame 62 along the clearance groove 14 to prevent the top blister tray from completely detaching from the top of the blister tray limiting frame 62, which is not conducive to the separation and positioning of the trays.

[0037] Furthermore, the multi-axis transfer mechanism 5 includes a multi-axis robot 51 fixedly connected to the top of the machine 1, a fixed seat 52 connected to the output end of the multi-axis robot 51, a fixed plate 53 fixedly connected to the fixed seat 52, a quick-change plate 54 detachably connected to the fixed plate 53, and a multi-suction cup assembly 55 fixedly connected to the quick-change plate 54, wherein the fixed plate 53 is detachably and quickly connected to the quick-change plate 54 through a quick-change module 56. In actual use, a multi-suction cup assembly 55 of various specifications is equipped with a fixture fixed to the quick-change plate 54 adapted to PCBAs of corresponding specifications and spacings, and the quick-change plate 54 and the multi-suction cup assembly 55 are directly removed from the fixed plate 53 together, and a suitable multi-suction cup assembly 55 and a fixture fixed to the quick-change plate 54 are found for replacement, thereby avoiding disassembly and adjustment of the suction cup spacing of the multi-suction cup assembly 55, which is conducive to shortening downtime.

[0038] Furthermore, the quick-change module 56 includes a quick locker 561 and a locker cam sleeve 562 that cooperates with the quick locker 561 for quick-change locking. The locker cam sleeve 562 is fixedly connected to the fixed plate 53, and the quick locker 561 is fixedly connected to the quick-change plate 54.

Both ends of the fixed plate 53 are provided with a first mounting countersunk hole 15 for fixing and installing the locker cam sleeve 562, and both ends of the quick-change plate 54 are provided with a The quick-change plate 54 is further provided with a fourth clearance hole 17 connected to the second mounting countersunk hole 16, and the quick-change plate 54 passes through the fourth clearance hole 17 and cooperates with the locking cam sleeve 562 for quick-change locking; the multi-axis robot 51 is a four-axis robot; the multi-suction cup assembly 55 includes a plurality of third lifting cylinders 551 spaced apart on the quick-change plate 54, a suction cup seat 552 connected to the output end of the third lifting cylinder 551, and a suction cup body 553 fixedly connected to the suction cup seat 552.

[0039] By adopting the above technical solution, the quick locker 561 and the locker cam sleeve 562 are matched components. For example, the quick locker 561 is selected from the model BLL45-20 of Yiheta, and the locker cam sleeve 562 is selected from the model BLL53-9 of Yiheta, which can realize quick-change locking. The two quick-change modules 56 are used symmetrically, which is beneficial to improve the connection stability between the fixed plate 53 and the quick-change plate 54. In the multi-suction cup assemblies 55 of various specifications equipped in actual use, the difference is that the spacing between the two adjacent third lifting cylinders 551 of each multi-suction cup assembly 55 is different, so that the multi-suction cup assemblies 55 of various specifications and the fixture fixed to the quick-change plate 54 are adapted to the PCBA of corresponding specifications and spacing.

[0040] Furthermore, the plate-staggering machine further includes a code reader fixedly connected to the machine 1, and the multi-axis transfer mechanism 5 further includes an identification code 57 disposed on a side of the quick-change plate 54, and the code reader is used to read the information of the identification code 57. The identification code 57 is a two-dimensional code or a barcode; preferably, the identification code 57 is a two-dimensional code, and the identification codes 57 of the multi-suction cup assemblies 55 of various specifications are different and unique, so as to distinguish and match the corresponding PCBA plate-staggering. When in use, the code reader first reads the identification code 57 to determine whether it is applicable, so as to avoid misusing the multi-suction cup assembly 55 that does not correspond to it, resulting in the PCBA being unable to stagger.

[0041] In addition, the CCD detection mechanism 2, finished product conveying mechanism 7 and defective product conveying mechanism 8 belong to the prior art and are not described in detail here.
