[0002] The back side (BOT side) of a PCBA board typically does not have components and is mainly used for soldering and assembly. This side usually contains basic structures such as circuit traces and pads, and has a planar area; while components are mainly assembled on the front side (TOP side) of the circuit board.

[0003] The traditional PCBA board processing method involves placing the entire PCBA board upside down on the incoming material tray, separating and removing dust through a PCBA slitting machine, and then conveying it out of the PCBA slitting machine via a belt conveyor. Then, workers manually take the PCBA board out of the incoming material tray, flip it over, and put it into the material box, so that the back of the PCBA board in the material box is against the inner bottom surface of the material box. Moreover, the material box also needs to be manually handled and moved, which is labor-intensive and not conducive to saving labor. Summary of the Invention

Detailed Implementation

[0016] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0017] like Figure 1-17 As shown, a PCBA board packaging assembly includes a frame 1. The frame 1 has a material box trolley feeding area 11, a conveyor box placement area 12, and a PCBA board packaging area 13 connected in sequence. The packaging assembly also includes a PCBA material box placement mechanism 21 fixedly connected to the frame 1 and located in the material box trolley feeding area 11 and the conveyor box placement area 12, a PCBA material box conveying mechanism 31 fixedly housed in the frame 1 and located in the conveyor box placement area 12, and a PCBA board packaging area 13 fixedly connected to the frame 1 and located in the PCBA board packaging area 13. The PCBA board packing mechanism 41 of the 3 is used to position and transfer the boxes in the feeding area 11 of the box trolley and stack them to the feeding end of the PCBA box conveying mechanism 31. The PCBA box conveying mechanism 31 is used to unload the stacked boxes one by one to the middle of the PCBA box conveying mechanism 31 for loading. The PCBA board packing mechanism 41 is used to flip and move the PCBA boards 48 of the future material tray 49 into the boxes in the middle of the PCBA box conveying mechanism 31.

[0018] When this packing assembly is used in conjunction with an existing PCBA depaneling machine, the existing PCBA depaneling machine delivers a tray 49 containing the PCBA boards 48 that have been depaneled. At this time, the PCBA boards 48 on the tray 49 are located in the PCBA board packing area 13 and below the PCBA board packing mechanism 41. A trolley with stacked boxes is prepared in advance and pushed to the trolley feeding area 11 for loading. In actual use, the PCBA box stacking mechanism 21 is used to position and transfer the boxes on the trolley and stack them onto the PCBA box conveying mechanism 31. At the feeding end, the PCBA box conveying mechanism 31 unloads the stacked boxes one by one to the middle of the PCBA box conveying mechanism 31 for loading. Then, the PCBA board packing mechanism 41 flips and moves the PCBA boards 48 from the tray 49 into the box in the middle of the PCBA box conveying mechanism 31, so that the back of the PCBA boards 48 in the box abuts against the inner bottom surface of the box. The box filled with PCBA boards 48 is then sent to the next process by the PCBA box conveying mechanism 31, which helps to save manpower and reduce labor intensity.

[0019] Furthermore, the PCBA box stacking mechanism 21 includes a Z-axis drive unit 24 fixedly connected to the frame 1 and located on both sides of the box trolley feeding area 11, an XY-axis drive unit 25 fixedly connected to the output end of the Z-axis drive unit 24 and located in the box trolley feeding area 11 and the conveyor stacking area 12, a rotary box picking unit 26 fixedly connected to the output end of the XY-axis drive unit 25, and a box alignment unit 27 fixedly connected to the frame 1 and located above the conveyor stacking area 12. The Z-axis drive unit 24 and the XY-axis drive unit 25 cooperate to drive the rotary box picking unit 26 to move along the XYZ axes. The rotary box picking unit 26 is used to push and suck up the box and adjust the length direction of the box to the Y-axis. The box alignment unit 27 is used to align the length position and width position of the box.

[0020] When the trolley is pushed to the trolley feeding area 11 for loading, the Z-axis drive unit 24 and the XY-axis drive unit 25 work together to drive the rotary box picking unit 26 to move along the XYZ axes to above the trolley. The rotary box picking unit 26 pushes the box on the trolley and adjusts the length direction of the box to the Y-axis. Then, the Z-axis drive unit 24 and the XY-axis drive unit 25 work together to transfer the box to the box alignment unit 27. The box alignment unit 27 aligns the length and width of the box. The rotary box picking unit 26 then pushes the box on the box alignment unit 27. Finally, the Z-axis drive unit 24 and the XY-axis drive unit 25 work together to transfer the box, stacking it on the PCBA box conveying mechanism 31. This helps save manpower and reduce labor intensity.

[0021] Furthermore, the Z-axis drive unit 24 includes a motor base 241 fixedly connected to the top of the frame 1, a servo geared motor 242 fixedly connected to the motor base 241, two first bearings 243 fixedly connected to both sides of the top of the frame 1, a drive shaft 244 fixedly connected at both ends to the inner rings of the two first bearings 243 respectively, a first synchronous belt drive 245 connecting the servo geared motor 242 and the drive shaft 244, two second bearings 246 fixedly connected to both sides of the bottom of the frame 1, a first rotating shaft 247 fixedly connected to the inner ring of the second bearings 246, and a drive shaft 244. The frame 1 includes a second synchronous belt drive 248 that engages with the first rotating shaft 247, a synchronous belt toothed plate 249 that cooperates with the synchronous belt of the second synchronous belt drive 248, a connecting seat 2410 that cooperates with the synchronous belt toothed plate 249 to fix and clamp the synchronous belt of the second synchronous belt drive 248, at least two Z-axis slide rails 2411 that are fixedly connected to both sides of the frame 1, and a first slider 2412 that slides in cooperation with the Z-axis slide rails 2411. The first sliders 2412 on both sides of the frame 1 are fixedly connected to both sides of the XY axis drive unit 25, and the two connecting seats 2410 are fixedly connected to both sides of the XY axis drive unit 25.

[0022] Using the above technical solution, both the first synchronous belt drive 245 and the second synchronous belt drive 248 are existing technologies, consisting of two synchronous pulleys and a synchronous belt to achieve synchronous transmission, and are only used as an application here. In use, the servo reduction motor 242 drives the first synchronous belt drive 245 to rotate the transmission shaft 244. The transmission shaft 244 drives the synchronous belt toothed plate 249 and the connecting seat 2410 to rise and fall through the second synchronous belt drive 248, thereby driving the XY axis drive unit 25 to rise and fall. In addition, in this embodiment, the XY axis drive unit 25 is existing technology, consisting of two Y-axis linear modules and one X-axis linear module. The two Y-axis linear modules are fixedly connected to the two connecting seats 2410 one by one. The two ends of the X-axis linear module are fixedly connected to the output ends of the two Y-axis linear modules. The output end of the X-axis linear module is fixedly connected to the rotating box-retrieving unit 26, and is only used as an application here.

[0023] Furthermore, the rotary box-retrieving unit 26 includes a base 261 fixedly connected to the output end of the XY-axis drive unit 25, a rotary cylinder 262 fixedly connected to the bottom of the base 261, a wide-type finger cylinder 263 fixedly connected to the output end of the rotary cylinder 262, and two vacuum suction cups 264 respectively fixedly connected to the two finger tips of the wide-type finger cylinder 263. The suction surface of the vacuum suction cup 264 is located on the side of the vacuum suction cup 264 away from the wide-type finger cylinder 263. The wide-type finger cylinder 263 and the two vacuum suction cups 264 cooperate to press and suction the two inner sides of the box in the width direction. The box alignment unit 27 includes a hanging beam 271 fixedly connected to the frame 1 and located above the box-sanding area 12 of the conveyor, a fixed seat 272 fixedly connected to the hanging beam 271, a Y-axis drive assembly 273 fixedly connected to the fixed seat 272, and a drive assembly 273 fixedly connected to the output end of the Y-axis drive assembly 273. The system comprises a positioning base plate 274, a first guide rod cylinder 275 fixedly connected to one end of the positioning base plate 274 away from the material box trolley feeding area 11, and a positioning push plate 276 fixedly connected to the output end of the first guide rod cylinder 275. The first guide rod cylinder 275 and the positioning push plate 276 cooperate to push the material box to the correct length position. Two symmetrically distributed guide alignment strips 28 are fixedly connected to both sides of the positioning base plate 274. The two guide alignment strips 28 cooperate to align the width position of the material box. The Y-axis drive assembly 273 includes a second guide rod cylinder 2731 fixedly connected to the fixed base 272, a second slider 2732 fixedly connected to both sides of the fixed base 272, and a Y-axis slide rail 2733 fixedly connected to both sides of the bottom surface of the positioning base plate 274. The Y-axis slide rail 2733 slides in cooperation with the second slider 2732. The output end of the second guide rod cylinder 2731 is fixedly connected to the bottom surface of the positioning base plate 274.

[0024] Using the above technical solution, during use, the wide-type finger cylinder 263 drives two vacuum suction cups 264 to press against the two inner sides of the material box in the width direction. The vacuum suction cups 264 vacuum and adsorb the two inner sides of the material box in the width direction. After the material box is lifted by the cooperation of the Z-axis drive unit 24 and the XY-axis drive unit 25, the length direction of the material box is adjusted to the Y-axis by the rotary cylinder 262. In this embodiment, when the material box needs to be transferred to the material box alignment unit 27, the Y-axis drive component 273 drives the alignment plate 274 to approach the end of the XY-axis drive unit 25. After the material box is placed into the material box alignment unit 27, the first guide rod cylinder 275 drives the alignment push plate 276 to push and align the length position of the material box. When the material box needs to be transferred to the PCBA material box conveying mechanism 31, after the rotating box picking unit 26 tops and sucks up the material box, the Y-axis drive component 273 drives the alignment plate 274 away from the end of the XY-axis drive unit 25 to make way for the material box to move down.

[0025] Furthermore, the PCBA box conveying mechanism 31 includes a machine base fixedly housed in the frame 1 and located in the conveyor box loading area 12, and two symmetrically arranged box conveyor units on the top of the machine base. Each box conveyor unit includes a belt conveyor 32 fixedly connected to the top of the machine base, a stacked box unloading device 33 fixedly connected to the outside of the machine base and close to the box input end of the belt conveyor 32, and a box positioning component 34 fixedly connected to the outside of the machine base and close to the middle of the belt conveyor 32. The belt conveyor 32 and the stacked box unloading device 33 cooperate to unload the stacked boxes one by one to the middle of the belt conveyor 32. The box positioning component 34 is used to intercept and position the boxes.

[0026] When the PCBA box conveying mechanism 31 is actually used after the boxes are stacked at the input end of the belt conveyor 32, the belt conveyor 32 and the stacked box unloading device 33 work together to unload the stacked boxes one by one to the middle of the belt conveyor 32. At the same time, the box positioning component 34 intercepts and positions the box so that the PCBA board 48 can be loaded into the box. Then the box filled with PCBA board 48 is sent to the next process by the belt conveyor 32, which helps to save manpower and reduce labor intensity.

[0027] Furthermore, the stacked bin unloading device 33 includes a bin lifting drive assembly 331 fixedly connected to the outside of the machine base and near the bin input end of the belt conveyor 32, and a bin clamping assembly 332 fixedly connected to the output end of the bin lifting drive assembly 331. The bin lifting drive assembly 331 and the bin clamping assembly 332 cooperate to lift the second-to-last stacked bin and detach it from the first-to-last stacked bin. The bin lifting drive assembly 331 includes a side support 3311 fixedly connected to the outside of the machine base and near the bin input end of the belt conveyor 32, and a Z-axis lead screw module 3312 fixedly connected to the side support 3311. The output end of the Z-axis lead screw module 3312 is fixedly connected to the bin clamping assembly 332. The bin clamping assembly 332 includes components connected to the... The output end of the material box lifting drive assembly 331 is fixedly connected to a T-shaped support plate 3321 and two clamping arm assemblies 3322 fixedly connected to both ends of the T-shaped support plate 3321. The two clamping arm assemblies 3322 cooperate to clamp the material box. The clamping arm assembly 3322 includes a third guide rod cylinder 33221 fixedly connected to the T-shaped support plate 3321, a clamping arm 33222 fixedly connected to the output end of the third guide rod cylinder 33221, a Y-guide rail 33223 fixedly connected to one end of the T-shaped support plate 3321, and a third slider 33224 slidably connected to the Y-guide rail 33223 and fixedly connected to the clamping arm 33222. A protrusion 35 is fixedly connected to the top of the clamping arm 33222. The protrusions 35 of the two clamping arm assemblies 3322 are used to limit the engagement with the grooves on the front and rear sides of the material box.

[0028] Using the above technical solution, when the belt conveyor 32 and the stacked bin unloading device 33 cooperate to unload the stacked bins one by one towards the middle of the belt conveyor 32, the bin lifting drive component 331 and the bin clamping component 332 cooperate to lift the second-to-last bin and detach it from the last bin. Simultaneously, the bins above the second-to-last bin are also lifted. At this time, the belt conveyor 32 operates to transport the last bin towards the middle of the belt conveyor 32 until it is intercepted by the bin positioning component 34. Then, the bin lifting drive component 331 and the bin clamping component 332 cooperate to lower the second-to-last bin onto the belt conveyor 32, completing one bin unloading process. The Z-axis lead screw module 3312 is prior art and is only used here as an application to drive the bin clamping component 332 to lift and lower.

[0029] It should be noted that the material box clamped by this solution has grooves on the front, back, left and right sides of its outer side. The protrusions 35 of the two clamping arm assemblies 3322 work together with the grooves on the front and back sides of the material box to limit the movement. This allows the two clamping arms 33222 to clamp the material box while the protrusions 35 abut against the grooves from top to bottom when the material box is lifted, thus preventing the material box from loosening and slipping.

[0030] Furthermore, the material box positioning assembly 34 includes a first cylinder seat 341 fixedly connected to the outside of the machine base and near the middle of the belt conveyor 32, a fourth guide rod cylinder 342 fixedly connected to the first cylinder seat 341, a side top plate 343 fixedly connected to the output end of the fourth guide rod cylinder 342, a second cylinder seat 344 fixedly connected to the outside of the machine base and near the middle end of the belt conveyor 32, a fifth guide rod cylinder 345 fixedly connected to the second cylinder seat 344, and a limiting stop 346 fixedly connected to the output end of the fifth guide rod cylinder 345. The side top plate 343 is used to position the material box. The outer groove of the limit stop 346 is used to prevent the material box from being output to the discharge end of the belt conveyor 32. The PCBA material box conveying mechanism 31 also includes a barcode reader unit 36 ​​fixedly connected to both sides of the machine base. The barcode reader unit 36 ​​includes a gantry frame 361 fixedly connected to both sides of the machine base, an X-direction linear module 362 fixedly connected to the gantry frame 361, a connecting arm 363 fixedly connected to the output end of the X-direction linear module 362, and an industrial barcode reader 364 fixedly connected to the connecting arm 363. The industrial barcode reader 364 is used to read the identification code at the front end of the material box.

[0031] Using the above technical solution, in use, the fifth guide rod cylinder 345 drives the limit stop 346 to descend, preventing the material box from being output to the outlet end of the belt conveyor 32. Then, the fourth guide rod cylinder 342 drives the side top plate 343 to engage with a groove on the outer side of the material box for limiting. At this time, the position of the material box is the target position referred to in the background technology. Furthermore, using the material box positioning component 34 to intercept and position the material box helps to prevent the material box from being misplaced. The X-axis linear module 362 is existing technology, used to drive the connecting arm 363 to move in the X direction, and is only used here as an application. The industrial barcode reader 364 is existing technology, such as the Hikvision MV-ID2016M, used to read the identification code at the front end of the material box, and is only used here as an application.

The lifting drive unit 45, the flipping drive unit 46, and the suction cup assembly 47 cooperate to pick up the PCBA board 48 from the incoming tray 49 and flip it over. The XYZ three-axis drive unit 42, the rotary drive unit 43, and the gripping plate assembly 44 cooperate to grab the PCBA board 48 from the suction cup assembly 47 and transfer it.

[0033] When the PCBA board packing mechanism 41 is used in conjunction with an existing PCBA depaneling machine, the existing PCBA depaneling machine sends out a tray 49 containing PCBA boards 48 that have been depaneled. At this time, the PCBA boards 48 on the tray 49 are located directly below the suction cup assembly 47. When the PCBA board packing mechanism 41 is working, the lifting drive unit 45, the flipping drive unit 46, and the suction cup assembly 47 work together to pick up the PCBA boards 48 from the tray 49 and flip them over so that the front of the PCBA boards 48 is facing up. Then, the XYZ three-axis drive unit 42, the rotary drive unit 43, and the gripping assembly 44 work together to grab the PCBA boards 48 on the suction cup assembly 47 and transfer them to the material box, thus completing the PCBA board packing operation. After flipping by the flipping drive unit 46, the back of the PCBA boards 48 in the material box can be pressed against the inner bottom surface of the material box. This PCBA board packing mechanism 41 helps to save manpower and reduce labor intensity.

[0034] It should be noted that in actual use, since the incoming material tray 49 has multiple rows of spaced PCBA board receiving slots, the PCBA depaneling machine uses the belt conveyor 32 to control the displacement of the incoming material tray 49 to cooperate with the packing mechanism of this application to pick up the PCBA board 48. The PCBA depaneling machine and the belt conveyor 32 are prior art and are not part of the invention of this application; they are only used as an explanation of the scenario in which this application operates.

The sixth guide rod cylinder 441 is used to drive the thin pneumatic finger 442 to move up and down. The two clamping claws 443 cooperate to grip the PCBA board 48. The bottom of the inner side of the clamping claw 443 is provided with a groove 410 for engaging with the side edge of the PCBA board 48.

[0036] In this embodiment, there are two gripping plate assemblies 44, which are symmetrically arranged. The side edges of the PCBA board 48 are the same as the side edges of the PCB board. The grooves 410 of the two clamping claws 443 engage with the two side edges of the PCBA board 48 to prevent the PCBA board 48 from loosening and slipping during the clamping process.

[0037] Furthermore, the lifting drive unit 45 includes a second base 451 fixedly connected to the frame 1, a seventh guide rod cylinder 452 fixedly connected to the second base 451, a lifting slide rail 453 fixedly connected to the side of the second base 451, and a fourth slider 454 slidably connected to the lifting slide rail 453. The output end of the seventh guide rod cylinder 452 and the fourth slider 454 are both fixedly connected to the tilting drive unit 46. The seventh guide rod cylinder 452 is used to drive the tilting drive unit 46 to move up and down. The tilting drive unit 46 includes a third base 461 fixedly connected to the output end of the lifting drive unit 1, a second stepper motor 462 fixedly connected to the third base 461, a tilting shaft 463 rotatably mounted on the third base 461 via bearings, and a connecting to the second... The stepper motor 462 and the third synchronous belt drive 464 of the flip shaft 463 are fixedly connected to one side of the suction cup assembly 47.

The suction cup assembly 47 includes a flip suction cup base 471 fixedly connected to the output end of the flip drive unit 46, a plurality of vacuum connectors 472 fixedly connected to the flip suction cup base 471, and a plurality of suction cup bodies 473 fixedly connected to the bottom of the flip suction cup base 471. The suction cup bodies 473 are used to pick up the PCBA board 48 of the incoming material tray 49. Taking advantage of the fact that the back of the PCBA board 48 has a planar area, the suction cup bodies 473 can pick up the PCBA board 48 of the incoming material tray 49.

[0038] The above technical solution, with the sliding cooperation between the lifting slide rail 453 and the fourth slider 454, improves the connection stability of the flip drive unit 46 and prevents easy shaking during the lifting and lowering process of the flip drive unit 46 driven by the seventh guide cylinder 452. In use, the second stepper motor 462 drives the third synchronous belt drive 464 to rotate the flip shaft 463 180°, causing the flip shaft 463 to rotate the suction cup assembly 47 along with the PCBA board 48 180°, completing the flipping operation of the PCBA board 48. In this embodiment, the third synchronous belt drive 464 includes a main synchronous pulley fixedly connected to the output end of the second stepper motor 462, a secondary synchronous pulley fixedly connected to one end of the flip shaft 463, and a synchronous belt connecting the main synchronous pulley and the secondary synchronous pulley. This is prior art and is only used as an application example.

[0039] Furthermore, the suction cup assembly 47 also includes two symmetrically distributed and fixedly connected to the bottom of the flip suction cup base 471, the two alignment claws 474 cooperate to align and abut against the two side edges of the PCBA board 48, so that the position of the PCBA board 48 can be aligned during the process of the suction cup assembly 47 pressing down to pick up the PCBA board 48, and avoid the PCBA board 48 being misplaced and causing adverse effects on the picking operation.

[0040] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
