The product to be cleaned is automatically loaded onto the product detection and wiping device for positioning and cleaning through the product feeding device, and the product unloading device realizes automatic unloading of the cleaned product. The automatic positioning of the pad of the product to be cleaned is realized through the cooperation of the product carrying mechanism and the visual component of the product detection and wiping device.

The transfer component accurately places the product from the detection carrier onto the wiping carrier, which facilitates the multi-axis moving mechanism to accurately drive the wiping mechanism to clean and wipe the product's pad. 5. The wiping platform is equipped with a flip plate to facilitate the downward flipping of the glass cover of the product when the product is placed on the wiping platform, so that the pads of the FPC part of the product can be exposed, making it easier for the wiping mechanism to move to the pad position to wipe and clean the pads. 6. The second product pressure rod is set on the wiping platform, and the first product pressure rod is set on the inspection platform.

The mating hole 5423 is rectangular, with the long side of the rectangle perpendicular to the direction of movement of the swing plate 5422, the short side of the rectangle parallel to the direction of movement of the swing plate 5422, and half the value of the long side of the rectangle greater than the maximum distance from the rotation axis of the eccentric wheel 5432 to the edge of the eccentric wheel 5432; or the mating hole 5423 is elliptical, with the long axis of the ellipse perpendicular to the direction of movement of the swing plate 5422, the short axis of the ellipse parallel to the direction of movement of the swing plate 5422, and the long axis of the ellipse greater than the maximum distance from the rotation axis of the eccentric wheel 5432 to the edge of the eccentric wheel 5432. This facilitates the cooperation between the eccentric wheel 5432 and the mating hole 5423 to realize the reciprocating motion of the swing plate 5422 along the first guide rail 433, thereby driving the wiping head 541 to wipe the pad back and forth.

[0053] See also Figure 1 、 Figure 2 、 Figures 12 to 15 Preferably, the lifting mechanism 55 includes a first telescopic cylinder 551, which is fixed to the mounting plate 51. A second longitudinal guide rail 552 is provided on the back of the mounting plate 51. The second guide rail 552 is connected to a connecting plate 553 via a second slider. The lower end of the connecting plate 553 is fixedly connected to the lifting plate 5421. The first telescopic cylinder 551 drives the connecting plate to move vertically along the second guide rail 552, thereby driving the lifting plate 5421 to move vertically, thereby driving the wiping head 541 to approach or move away from the product's pad.

[0054] See also Figure 1 、 Figure 2 、 Figures 12 to 15Preferably, the pressure regulating assembly 56 includes a pressure sensor (not marked) and a pressure regulating cylinder 561. The pressure regulating cylinder 561 is fixed on the extended end of the first telescopic cylinder 551. The pressure sensor is arranged between the pressure regulating cylinder 561 and the lifting plate 5421. The pressure regulating cylinder 561 is connected to a pressure regulating valve (not shown). The first telescopic cylinder 551 is gradually extended to gradually press the wiping head 541 against the product's pad. When the pressure sensor detects excessive pressure, the pressure regulating valve reduces the pressure value of the pressure regulating cylinder 561. The pressure regulating cylinder 561 is retracted to a certain length due to the pressure transmitted back from the wiping head 541, thereby reducing the pressure between the wiping head 541 and the pad. Conversely, the pressure regulating valve is increased, and the pressure regulating cylinder 561 is further extended to a certain length so that the pressure detected by the pressure sensor vertically reaches a specified value range. Different products may have slight differences in size, resulting in inconsistent pressure between the wiping head 541 and the product when the lifting mechanism 55 moves the same distance each time. Therefore, the pressure regulating assembly 56 is provided to keep the pressure value between the wiping head 541 and the product pad within a reasonable range, which can not only ensure the cleaning effect of the product, but also protect the product. It should be noted that the detection circuit of the pressure sensor and the adjustment of the corresponding components based on the detection value of the pressure sensor are prior art and do not require specific protection, so they will not be described in detail.

[0055] See also Figure 1 、 Figure 2 、 Figures 7 to 9 、 Figures 12 to 15 Preferably, a material strip positioning mechanism 57 is provided on each side of the wiping mechanism 54 on the mounting plate 51. The material strip positioning mechanism 57 includes a positioning cylinder 571 and a positioning roller 572. The positioning roller 572 is rotatably mounted on the mounting plate 51. The positioning cylinder 571 is mounted on the mounting plate 51 and is located above the positioning roller 572. The push plate of the positioning cylinder 571 approaches or moves away from the positioning roller 572. When the wiping head 541 swings back and forth for wiping, the positioning cylinders 571 of the material strip positioning devices 7 on both sides press against the positioning roller 572, thereby pressing against the wiping material strip between the two. This prevents the wiping material strip from loosening or shifting relative to the wiping head during the wiping process, thereby ensuring a good wiping and cleaning effect.

[0056] See also Figure 1 、 Figure 2 、 Figures 7 to 9 、 Figures 12 to 15Preferably, a set of guide rollers 573 are provided on both sides of the wiping mechanism 54 on the mounting plate 51. The wiping material strip is guided by the guide rollers 573 to pass between the positioning rollers 572 and the positioning cylinder 571. This guides the transfer of the wiping material strip, allowing the strip to pass through the strip positioning mechanism 57 to the wiping head 541 and be wound onto the driving wheel 53.

[0057] See also Figure 1 、 Figure 2 、 Figures 12 to 15 Preferably, each guide roller assembly 573 includes two guide rollers 5731, which are mounted on the mounting plate 51 via roller shafts 5732. The guide rollers 5731 can move relative to the roller shafts 5732 in the same direction as the movement of the swing assembly 542. One guide roller 5731 is located outside the positioning device; the other guide roller 5731 is located between the wiping mechanism 54 and the positioning roller 572. In conjunction with the wiping action of the wiping head 541, the guide rollers 5731 move in coordination, ensuring smoother transfer of the wiping material with less resistance.

[0058] See also Figure 1 、 Figure 2 、 Figures 12 to 15 The swing assembly 542 is located next to the wiping head 541 and is provided with a cleaning agent supply head 58. The cleaning agent supply head 58 is connected to a solvent tank (not shown) via a pipeline (not shown), and the cleaning agent is sprayed from the cleaning agent supply head 58. Alternatively, the wiping head 541 is hollow and connected to the solvent tank via a pipeline, and the cleaning agent is sprayed from the wiping head 541. The cleaning agent can be soaked into the wiping material belt, achieving a better wiping and cleaning effect on the pad.

[0059] See also Figure 1 、 Figure 2 、 Figures 12 to 15 Preferably, the driven wheel 52 and the driving wheel 53 are respectively driven by a first motor 59. One first motor drives the driving wheel 53 to rotate, thereby realizing the automatic winding of the wiping material tape, and the other first motor 59 drives the driven wheel to unwind the material. An auxiliary traction wheel group 510 is provided next to the driving wheel for auxiliary traction of the wiping material tape. The auxiliary traction wheel group 510 includes a power wheel and a clamping wheel. The power wheel is driven by a motor, and the clamping wheel is pressed against the power wheel. The wiping material tape passes between the clamping wheel and the power wheel and is wound around the driving wheel 53. Since the wiping material tape is clamped between the power wheel and the clamping wheel, the rotation of the power wheel can drive the wiping material tape to move forward.

[0063] The present invention has the following working principle:

[0064] The products are fed from the upstream production line onto the feeding conveyor 11, which then drives the products to the end of the conveyor.

[0065] The alignment components are aligned. During alignment, the side push plates 1322 on both sides are driven by the side alignment cylinders 1321 to move in opposite directions. The alignment push plates 1312 are driven by the first alignment cylinder 1311 to move toward the incoming direction of the feed conveyor 11. The mechanical alignment of the product can be completed by squeezing the product. A visual inspection camera 14 is provided above the end of the feed conveyor 11. The visual inspection camera 14 is used to detect the position of the product on the feed product conveyor, so that the feed robot 12 can accurately grab the product from the feed conveyor.

[0066] The feeding robot 12 grabs the product from the end of the feeding conveyor belt 11 and places it on the idle testing platform 33 of one group of product carrying mechanisms 3 of the product inspection wiping device. The first vacuum adsorption hole of the first vacuum adsorption plate 332 on the testing platform 33 and the first FPC vacuum adsorption hole on the first FPC adsorption block 333 use negative pressure to suck the product. The first product pressing rod 334 moves downward to press the product. After that, the first moving component 31 drives the testing platform 33 to move to the bottom of the visual inspection component 6 on the gantry 7 for inspection and positioning.

[0067] After the inspection is completed, the first moving component 31 drives the inspection platform 33 to move to the bottom of the transfer component 32 of the gantry 7 according to the inspection positioning data of the visual inspection component 6, and the lifting component 321 (telescopic cylinder) of the transfer component 32 drives the lifting connection component 322 to descend, driving the vacuum suction cup to absorb the product on the inspection platform 33 (at this time, the first FPC vacuum adsorption hole and the first vacuum adsorption hole release the negative pressure), and then the lifting component 321 rises, and the first moving component 31 drives the wiping platform 34 to move to the bottom of the transfer component 32, and the lifting component 321 extends to place the product on the wiping platform 34, and the second FPC adsorption block 344 and the second vacuum adsorption plate 345 on the fixed plate 342 of the wiping platform 34 respectively negatively absorb the FPC and the glass cover, and the second product pressure rod 346 moves down to press the FPC; the first moving component drives the wiping platform 34 to move to the wiping station;

[0068] Afterwards, the multi-axis moving mechanism 4 drives the pad wiping module 5 to move to the top of the wiping carrier 34, so that it moves down close to the FPC pad of the product. The lifting mechanism 55 of the wiping module drives the wiping mechanism 54 to move down close to the pad of the product. When the wiping head 541 contacts the pad (during this process, if the pressure sensor detects that the pressure value is too high or too low, the pressure regulating valve adjusts the air pressure value of the pressure regulating cylinder 561, and the pressure regulating cylinder 561 is retracted to a certain length by the pressure transmitted back by the wiping head 541, and the pressure between the wiping head 541 and the pad is reduced; otherwise, it is increased.), the wiping mechanism 5 The positioning cylinders 571 of the strip positioning mechanism 57 on both sides push out the pressing rollers to clamp the wiping strip, so that the wiping strip and the wiping head 541 are relatively fixed; then the driving motor 5431 drives the eccentric wheel 5432 to rotate, and the swing plate 5422 is provided with a matching hole 5423 that matches the eccentric wheel 5432. The rotation of the eccentric wheel 5432 can drive the swing plate 5422 to move back and forth, thereby driving the wiping head 541 to wipe the pad back and forth. At this time, the cleaning agent is passed through the cleaning agent supply head 58 or the wiping head 541 to soak the wiping strip, and the product can be cleaned and wiped; see for details. Figures 12 to 14 .

[0069] After the wiping and cleaning is completed, the driving motor 5431 stops, the lifting mechanism 55 drives the wiping mechanism 54 to rise, the material tape positioning cylinder 571 retracts, and the active wheel 53 rotates and rewinds to remove the wiping material tape that has contacted the pad, so that the wiping material tape under the wiping head 541 is a clean material tape, the second vacuum adsorption plate 345 and the second FPC adsorption block 344 release the negative pressure, the second product pressure rod 346 rises, and the unloading robot 23 takes away the cleaned product, and places it on the first unloading conveyor belt 21 or the second unloading conveyor belt 22 according to the inspection result of the visual inspection module, and sends it to the next process station for processing.
