[0022] Specifically, in this embodiment, the tin brushing mechanism 200, the testing mechanism 300, the glue dispensing mechanism 400 and the buffer mechanism 500 are sequentially arranged, and the conveyor line 100 passes through the tin brushing mechanism 200, the testing mechanism 300 and the glue dispensing mechanism 400 in sequence, and the buffer mechanism 500 is arranged at the conveying tail end of the conveyor line 100, and the conveyor line 100 conveys the PCBAF to the tin brushing mechanism 200, and the tin brushing mechanism 200 brushes the tin slag on the surface of the conveyed PCBA. After the PCBA is tinned, the conveyor line 100 conveys the PCBA to the testing mechanism 300, and the testing mechanism 300 tests the performance of the PCBA. After the test, the conveyor line 100 then conveys the PCBA to the glue dispensing mechanism 400, which dispenses glue on the PCBA. After dispensing glue, the glue dispensing mechanism 400 pushes the PCBA to the cache mechanism 500, which caches the PCBA after dispensing glue, thereby making the manufacturing process of the PCBA smooth and making the layout of each mechanism more coherent, without the need for manual transportation of the PCBA. At the same time, the cache mechanism 500 will continue to heat the cached PCBA so that the silicone dispensed on the PCBA can solidify quickly, thereby improving the manufacturing efficiency of the PCBA, making its production capacity reach more than 2000pcs / H, and improving the company's production capacity.

[0023] See also Figure 2 and Figure 3In order to improve the manufacturing efficiency of PCBA, the tin brushing mechanism 200 in this embodiment includes a tin brushing pressing unit 210, a tin brushing bracket 220 and a tin brushing motor 230.

The tin brush pressing cylinder 214 drives the tin brush pressing plate 213 to move up and down.

[0024] When the conveyor line 100 conveys the PCBA to the tin brushing mechanism 200, the tin brushing moving module 211 drives the tin brushing pressing plate 213 to move and move to the top of the PCBA, and then the tin brushing pressing cylinder 214 drives the tin brushing pressing plate 213 to move downward, and the PCBA is pressed and fixed by the tin brushing pressing plate 213. After pressing and fixing, the tin brushing moving module 211 moves with the conveyor line 100 and carries the PCBA. When the PCBA moves, it passes through the tin brushing bracket 220. The roller brush 240 on the PCBA is driven by the tin brushing motor 230 to transfer, and the rotating roller brush 240 is used to sweep the tin slag from the moving PCBA, and the swept tin slag will fall into the slag receiving tray 250 below the roller brush 240, so as to realize the automatic tin brushing of the PCBA and improve the manufacturing efficiency of the PCBA. At the same time, the slag receiving tray 250 can prevent the tin slag from falling on the all-in-one machine, so that the whole machine is clean and the tin slag can be recycled conveniently.

[0025] See also Figures 4 to 6After the PCBA is tinned, the conveyor line 100 will convey the PCBA to the testing mechanism 300, and the testing mechanism 300 will automatically detect the performance of the PCBA.

[0026] After the conveyor line 100 conveys the tinned PCBA to the testing mechanism 300, the test positioning unit 310 will rise upward to position the PCBA. After positioning, the clamping cylinders 321 in the test clamping units 320 on both sides will drive the clamping plates 322 to move toward the sides of the PCBA, and clamp and fix the PCBA through the clamping plates 322 on both sides to prevent the PCBA from shaking during testing, thereby ensuring the quality of the PCBA during testing. After the PCBA is clamped and positioned by the test clamping units 320 on both sides, the detection cylinder 332 in the detection unit 330 will drive the detection pressure plate 333 to move downward. During the downward movement, the detection pressure plate 333 will move downward with the probe 334, and contact the PCBA through the probe 334, thereby realizing the detection of various performances of the PCBA, thereby ensuring the production quality of the PCBA.

[0033] When the PCBA dispensing is completed, the pushing module 431 of the pushing unit 430 will drive the pushing cylinder 432 to move, so that the pushing plate 433 connected to the pushing cylinder 432 moves to the rear end of the PCBA, and the pushing cylinder 432 will drive the pushing plate 433 to move forward.

When the glue of the PCBA is solidified, the discharge cylinder 542 of the discharge unit 540 will drive the discharge push plate 543 to move, and when the discharge push plate 543 moves, it will push the PCBA out of the cache rotating lifting unit 520 and push it to the next process, so as to complete the caching of the PCBA, and accelerate the solidification of the PCBA glue through the hot air blower 530, improve the manufacturing efficiency of the PCBA, and make the PCBA manufacturing capacity reach more than 2000pcs / H, and finally improve the enterprise's production capacity.

[0038] See also Fig.14 In order to achieve caching of multiple PCBAs, the cache rotation and lifting unit 520 in this embodiment includes a cache lifting motor 521, a cache lifting screw 522, a cache mounting plate 523, a cache rotating disk 524 and a cache rotating motor 525. The cache lifting screw 522 is connected to the cache lifting motor 521, and the cache lifting motor 521 drives the cache lifting screw 522 to rotate. The cache mounting plate 523 is connected to the cache lifting screw 522. When the cache lifting screw 522 rotates, the cache mounting plate 523 is lifted and lowered. The cache rotating disk 524 and the cache rotating motor 525 are respectively arranged on the cache mounting plate 523, and the cache rotating motor 525 is connected to the cache rotating disk 524 and drives the cache rotating disk 524 to rotate. There are a number of cache cavities 526 in a ring array on the cache rotating disk 524.

[0039] The cache cavity 526 in this embodiment has a plurality of cache slots 526a arranged up and down, and each cache slot 526a has a gap, and the gap can ensure that the PCBAs cached up and down will not contact each other, so as to increase the speed of glue solidification, thereby improving the PCBA manufacturing efficiency.

[0040] When the PCBA dispensing is completed, the pushing unit 430 will directly push the PCBA into the cache slot 526a of the cache cavity 526 for caching. After the PCBA is cached in the previous cache slot 526a, the cache lifting motor 521 will drive the cache lifting screw rod 522 to rotate. When the cache lifting screw rod 522 rotates, it will drive the cache mounting plate 523 to rise. The cache mounting plate 523 drives the cache rotating disk 524 and the cache cavity 526 to move upward, and the pushing unit 430 will push the rear PCBA into the next cache slot 526a of the cache cavity 526, and so on, until this group of cache cavities 526 are filled. At this time, the cache lifting motor 521 will drive the cache rotating disk 524 and the cache cavity 526 to move downward and reset. At the same time, the cache rotating motor 521 will drive the cache rotating disk 524 to rotate to fill another group of empty cache cavities 526. 26 rotates to cooperate with the pushing unit 430, and the pushing unit 430 pushes the PCBA to the cache slot 526a of this group of cache cavities 526, and so on. Under the action of the hot air blower 530, the PCBA in the previous group of cache cavities 526 can quickly solidify the glue on the PCBA, and when the cache rotating motor 521 drives the cache cavities 526 to rotate in turn, the cache cavity 526 with the glue solidified PCBA in front will rotate to the discharge position and cooperate with the discharge unit 540, and the discharge unit 540 will directly push out the PCBA in this group of cache cavities 526 in turn, and the pushing and pushing are synchronized. When a PCBA is pushed in, a solidified PCBA will be pushed out, and this cycle will eventually make the PCBA manufacturing process smooth, and the solidification speed of the PCBA dispensing glue is increased, the PCBA manufacturing efficiency is improved, and the enterprise's production capacity is ensured.
